Experienced mechanics share their insights in answering this question :
Hello. Without additional detail as to what you are referring to by saying the fuel disengaged, this may be difficult to diagnose without running a scanner on the vehicle. However, there are many things that can cause the fuel supply to be shut down, such as faulty wiring connections, bad fuel injectors, failing mass air flow sensor, low fuel pressure, a bad ECM, a bad O2 sensor, and many others.

Depending on the severity of this, your car’s ECM has a "fail safe" mode that will sometimes engage, shutting down most of the car’s major engine and drivetrain components as a means to prevent further damage and maintain safety of the driver. This may also explain the transmission shutting down as well. In either case, this is something that will need to be diagnosed by a professional. A certified technician from YourMechanic can come to your car’s location to inspect the transmission problem and advise you on a repair.

How to Identify and Fix Common car Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced mechanics :

The most common include leaking internal or external transmission seals; mechanical damage to the transmission and/or the transfer case`s vital internal hard parts such as gears, drums, etc.; old, worn-out transmission fluid; improper fluid; electrical software and hardware glitches; worn drivetrain components; bad …
Low transmission fluid is one of the most common reasons for a slipping transmission. The most likely culprit is a problem in your system that`s causing the transmission fluid to leak.
Common reasons for this to happen: *Low Fluid in Transmission – Both manual and automatic transmissions require fluid (different types) in order to operate. If the fluid is low, there`s a chance that you won`t be able to change gears, particularly in an automatic transmission.
Transmission gears wear out and start slipping.

Over time gears can wear out – especially if they have been running hot and inefficiently due to lack of or worn out transmission fluid. Slipping gears are usually due to normal wear and tear, which causes them to not engage properly and to slip in and out of sync.

The Transmission Range Sensor tells the PCM the position of the transmission shifter. The PCM uses this information to control which gears of the transmission to enable or disable. When the TR sensor fails it can cause wrong gear starts, no upshifts, or what feels like a falling-out-of-gear condition.
What is the fix for a slipping transmission? It`s simple. Just pop the hood of your vehicle, locate the transmission switch, and change the setting from “SLIP” to “STABLE” . . . If only it were that easy.
When the transmission fluid isn`t clean or is blocked by a clogged filter, the internal components won`t have the lubrication they require to function properly. This could lead to shifting issues, grinding gears, slipping transmission or other common symptoms of transmission problems.
Some of the Mitsubishi Outlander cvt transmission problems are hard shifts and jerks. The transmission fluid needs to be replaced every 30,000 to 60,000 miles. Along with fluid changes, terrible sounds will come from the transmission…. Hard shifts could arise and that is not good.
To put it briefly, no you should never drive your vehicle if you believe there to be an issue with your transmission in any case. Once a transmission starts slipping it needs to immediately be repaired. Every time you drive it after you feel your transmission slip, it is a risk.
Improper Or Harsh Shifting

When there`s no speed signal coming from the sensors, shifting of gears will be a problem because the powertrain control module won`t control them correctly. This will make the transmission not work properly. It will either shift more quickly or roughly than expected.

For example, in some situations an oxygen sensor can cause poor shifting in your transmission – if the engine isn`t running correctly, the transmission control module may misinterpret when and where it`s supposed to be shifting, causing erratic behavior at the transmission.
Slipping, rough shifting, and delayed engagement troubles are often due to poor condition or lack of transmission fluid; that`s why it is so important to have the condition of your fluid checked and flushed every 30,000 – 50,000 miles.
When your manual transmission slips, 99 percent of the time, it is due to a worn-out clutch. Over extensive use, the clutch will wear thin and won`t be able to run as required. Ideally, your clutch needs to run anywhere from 20,000 to 200,000 miles before replacement.
If you go and replace the fluid after they are already worn out. this can cause slipping. The old fluid had contained particles that actually helped shifting, making it grittier to allow better gripping. New fluid doesn`t contain this material and may not grip as well, causing slippage.
A damaged fin or bearing in the torque converter can cause hesitation in the transmission shifting, or the transmission to slip out of gear entirely. This is because the engine torque is not being efficiently converted into the hydraulic pressure needed to shift gears within the transmission.
To test the torque converter, you must step on the pedal to the floor and accelerate your engine for up to five seconds. The reading for the revolutions per minute (RPM) will max out at the stall speed.
The torque converter is an essential component of automatic vehicles, and if it is damaged, it can lead to further transmission damage.
Mitsubishi Motors North America, Inc. (MMNA) is recalling certain model year 2015-2016 Outlander Sport vehicles and 2016 Outlander and Lancer vehicles. The affected vehicles are equipped with a constant velocity transmission (CVT) that, in certain driving conditions, may cause a delay in the vehicle accelerating.
2007 Mitsubishi Outlander transmission problems could include shifting delays, grinding when accelerating, a feeling of shakiness, or whistling noises and a burning smell coming from under the hood.
All Mitsubishi systems from the Mitsubishi 6000 BTU mini split to the 42,000 BTU mini split have at least one wireless remote control. These remote controls have a reset button at the bottom under the panel. Pressing the reset button ensures the remote is working correctly.
One of the most common issues is gear slippage. This occurs because the TCM is not giving the correct commands to shift, which can cause sudden shifting or not shifting at all. Another common symptom is failure to accelerate as usual. If your vehicle cannot change gears correctly, your car`s acceleration will suffer.
If your car is slipping between gears without any input, it`s dangerous for you and damaging for your engine. Low fluids and worn transmission bands can cause gear slipping.
But a blown fuse No. 38 becomes a likely candidate causing a loss of power to the transmission solenoids.

Was on highway fuel disengaged but still had transmission but a few minutes and transmission disengaged
ANSWER : Hello. Without additional detail as to what you are referring to by saying the fuel disengaged, this may be difficult to diagnose without running a scanner on the vehicle. However, there are many things that can cause the fuel supply to be shut down, such as faulty wiring connections, bad fuel injectors, failing mass air flow sensor, low fuel pressure, a bad ECM, a bad O2 sensor, and many others.

Depending on the severity of this, your car’s ECM has a "fail safe" mode that will sometimes engage, shutting down most of the car’s major engine and drivetrain components as a means to prevent further damage and maintain safety of the driver. This may also explain the transmission shutting down as well. In either case, this is something that will need to be diagnosed by a professional.

I have a 1981 e-350 with dual fuel tanks the p.o. added a third tank and 3 electric fuel pumps along with sepparate gauges and swi
ANSWER : The switch you are referring to is vended with the required electrical and fuel schematic (I just looked in the box) that answers your installation question. If you want an advance view, here is a link as well. Yes, you need a return line and just refer to the aforementioned link. If you are retrofitting back to OEM, I strongly encourage you to buy the original Factory Service Manual (FSM). There are lots of details attending this system and obviously it is difficult to recount it all here. The FSM will make your life much easier and you can then make sure your installation is perfect. Alternatively, YourMechanic can dispatch a certified mechanic and perform the whole retrofit and check out if you desire. Just request and schedule a generic service such as fuel pump service and the mechanic will come to your location and estimate the parts and labor required. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

Installed new delphi fuel pump and fram fuel filter. still no pressure on fuel rail valve and wont start. 2003 Chevrolet Tahoe
ANSWER : Hi there – I suspect you have weak power getting to the fuel pump. I would first check the voltage coming out of the fuel pump relay. If the contacts in the relay are burned, you will not get reliable current flow to the pump. Check the fuel pump ground as well (voltage drop across the ground, not just continuity). I recommend a fuel system inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.

Just replaced my fuel pump but its not getting any power tested fuel pump relay and fuel fuse both good tested the wires all good.
ANSWER : You need to look at the theft light on dash to make sure it comes on and goes off when you turn the key to the on position. If light comes on and stays on then your theft system is causing the fuel pump to not be engaged. I recommend you check the theft system and then scan the computer for theft system codes. You may need to reprogram the keys to work or you have an bad sensor for the ignition key in the steering column.

Put new fuel pump, still won’t start
ANSWER : Hi, it sounds like you have taken all the proper steps. The concern with the fuel gauge is a common issue when replacing the fuel pump. The fuel level sensor is a separate component attached to the fuel pump. This part does not always come with the fuel pump and sometimes is not interchangeable with aftermarket fuel pumps. Chevrolets have a common issue with fuel filters getting clogged. You always want to replace the fuel filter when replacing the fuel pump. This could cause the concern you are having. It may seem as you are getting enough fuel from the pressure regulator but if the pressure from the fuel tank is not correct, it will still not start. Another problem you could be having is spark. Have you recently changed the spark plugs? Make sure that they are gapped correctly. You need three things to make an engine run: fuel, spark, and air. If you need help, YourMechanic offers a repair and diagnosis service preformed by a certified mechanic that will commute to your location to look into why your car isn’t starting.

Transmission fluid leak, power loss, extremely high fuel usage.
ANSWER : Hello – I would focus on the transmission issue first. If you have the transmission fluid back to its proper level, check for problem codes, whether the Check Engine light is lit or not. An auto parts store will read these codes for you for free. Low fluid level can easily result in poor performance and burned clutches, and can cause foaming out of the filler dipstick and onto the engine. If after refilling transmission fluid, there are no problem codes, I would recommend having a Transmission Fluid Service completed by a mobile, professional mechanic, such as one from YourMechanic, to diagnose this problem, get an accurate assessment of damage and cost estimate for repairs. If there are transmission codes, and/or the "Wrench" symbol is still illuminated, I would recommend taking your vehicle to a reputable transmission repair facility for a thorough diagnostic analysis. The "high fuel consumption" indicated in the instrument cluster is likely a secondary indicator of the transmission issue. Resolve the transmission performance problem first, then check fuel mileage.

Fuel pressure
ANSWER : Hello,
You may want to try checking the fuel pump relay. The relay wires should have ground on two wires, power on one wire and switched power on another wire. To activate the fuel pump your ECU actually connects one of the ground wires to complete the circuit and send power to the fuel pump. If the wires all have power running through them, then it is likely you have a faulty relay. The wire coming from the fuel pump is the other ground wire. I would recommend having an expert from YourMechanic come to your location to diagnose your wiring as this can be very difficult and time consuming without the proper wiring diagram.

I have a truck that won’t run and is not getting gas to the engine. Fuel pump is running, have a new filter and new fuel pressure
ANSWER : Hi There,
It sounds like you may have a clogged fuel injector or potentially a faulty injector that is fried internally. I would suggest testing them if you have access to a multi meter. Disconnect the injector from the electrical connector and set your multi meter to Ohms mode and measure the resistance of the injector. After testing all injectors, compare the resistance. They should be the same or very close. If they are not, they will likely need to be replaced.
