last time my car ran it would stall if I did not keep the accelerator in a little, now it will not start. it sounds like it wants to fire but does not. I have changed the fuel filter but that didn't change how it is acting.
My car has 118000 miles.
My car has a manual transmission.

Hello there, the stalling and no start issues with your 1995 Mitsubishi 3000GT are likely related. Common faults that can cause both of these symptoms is the mass air flow sensor, vacuum leaks, fuel pump, throttle body issues, or throttle cable. In most of these cases a check engine light will be stored in the cars computer that may help narrow down the diagnosis. A qualified Technician such as one from YourMechanic will be able to diagnose your no start issues and make any repairs required.

The most common reasons a Mitsubishi 3000GT won`t start are a dead battery, an alternator problem, or failed starter.
There could be several reasons a Mitsubishi vehicle isn`t starting, including a dead battery, faulty alternator, clogged fuel filter, or a malfunctioning starter. To troubleshoot the issue, it`s important to diagnose the root cause and address it accordingly.
Fusible Links (Fuses) 3000GT & Stealth
These are all located under the hood in the main fuse box by the passenger headlight.
This usually means the battery is bad and incapable of handling a huge request for power to crank the engine over. Headlights begin white and bright, when you try to start the engine, they dim to nothing or almost nothing then as soon as you let go of the key, the headlights QUICKLY bounce back to white and bright.
If your vehicle won`t start, it`s usually caused by a dying or dead battery, loose or corroded connection cables, a bad alternator or an issue with the starter. It can be hard to determine if you`re dealing with a battery or an alternator problem.
Turn off the system, switch the isolator to off, wait 30 seconds, switch the isolator back on, wait a couple of minutes, and turn the whole system back on.
A failing fuel pump is a common factor in hard starting vehicles. Over time, a pump can wear out and not deliver the correct amount of fuel that an engine needs to run as it should. Clogged or dirty fuel filters, injectors, and lines can also restrict fuel delivery.
One of the best ways to determine if a car fuse has blown is by using a test light. It should illuminate both ends of the fuse, and, if it doesn`t, it needs to be replaced. Sometimes, a blown fuse is caused by a damaged wire, motor, or other part.
Turning your key turns your battery on, so if you`ve turned your key all the way and the lights come on, but the engine doesn`t turn over, your starter motor could be the culprit. Any signs of electrical failure could also indicate the starter motor needs help.
Your engine won`t start. While the cause could be a range of issues related to fuel, compression, or spark, the fuel pump is often a likely culprit.
BAD STARTER MOTOR
Another possible reason why your car won`t start even though your battery is in good condition is due to an issue with your starter motor. The starter motor is connected to the battery and has the vital role of actually getting the engine to fire.
The problem could be a weak fuel pump, leaking fuel injectors, worn starter, weak battery, or faulty temperature sensor. Good technicians will be able to test and determine the issue more accurately if they can experience the issue themselves.

Fuel pump engages. Batery good, alternator good volts, jump start helps when wont start. Temp does not matter. Intermittent?
Hello. Thank you for writing in. There are several reasons your vehicle may only start when jump starting. The first and most common is a build up of resistance that is causing you to need a boost of voltage to get the engine started. This may be due to poor battery cables, a bad ground connection, a poor starter solenoid, and a couple of other issues. The first thing you want to do is perform a visual inspection of the starting system. Make sure there is no corrosion build up in the battery cables. You can also check the resistance across these wires and make sure you have a solid connection between components. You then want to make sure the starter solenoid is doing its job. It is responsible for taking the small amount of electricity sent by the ignition and turning it into a huge electrical charge that is strong enough to push over the engine with the help of some gear ratios in its favor. Do some more testing, and stick to the basics before assuming its something seriously complicated.
Vehicle won’t start, once it’s jump started it only stays running until you turn it off, then it work start again without jumping.
Hi there. There could be two problems here. It is possible that your battery is bad and will not take a charge from your alternator while driving. In that case every time you shut your car off you will not have enough juice to start it again. Inspect your battery – it should have at least 12.5 to 13 volts to start your car, if it doesn’t you will need to replace the battery. The second problem could be that your alternator is bad and not charging your battery, in this case you will need to replace your alternator. Both the battery and the alternator can be tested in your car. If you would like to have the car checked for you, a certified professional from YourMechanic can come to your car’s location to diagnose the starting problem and proceed with repairs.
Cranks over start than dies
The idle air control valve is a small valve on the engine’s intake system that reads the air intake as it comes into the motor. This is controlled by the car’s ECM which uses this information to make adjustments to the air/fuel ratio depending on various inputs such as outside air temperature, intake air temperature, load and various other things. As you accelerate, your car’s engine is receiving a much higher dose of fuel than when at idle and conversely, when you let off the gas pedal, there is a sudden change in this fuel supply as a result of your foot letting off the pedal. When this happens, the job of the idle air control valve is to bring this deceleration down to a slow and smooth idle rather than suddenly cutting off the fuel supply causing the motor to die. When the idle air control valve is not working properly, this cause a disruption in this process resulting in the engine not being able to idle properly. I would recommend having a professional come to your location to diagnose and inspect your vehicle.
The car is having trouble starting up ,70 percent of the time it starts right up. the other 30 percent, it randomly won’t start its
Hey there thanks for writing in about your 1998 Honda Accord. This could be a few things. A faulty ignition switch, a failing crank sensor, or possibly other faulty sensors could be the cause. To have this taken care of, consider having a certified technician, such as one from YourMechanic, come to your car’s location to diagnose and repair the hard start issue.

Hi and thanks for contacting YourMechanic. Check the battery cables for more corrosion and clean them up again. You may need to put backing soda and water mixture on the terminals to clean the corrosion completely off. Make sure that the cables are tight and also tight on the starter solenoid. By rocking the vehicle back and forth and using the clutch to start the vehicle, this is an indication that the cable on the starter is either corroded or loose. If you need further assistance troubleshooting your starting system, then seek out a technician, such as one from YourMechanic, to diagnose and resolve the issue.
Wont start (Click), shift gear from P to R then back to P Starts it, after runs for a while it starts up fine.
Your vehicle has something called a neutral safety switch that will prevent the vehicle from starting when it is in any gear position other than park or neutral. Occasionally, this switch can malfunction causing the car to stall as soon as you put it into any gear. This switch usually also monitors gear selection data as well to transmit back to the computer. This switch is connected to the starter solenoid which allows it to complete the starter circuit only when the transmission is in park or neutral. I would suggest having a professional from YourMechanic come to your location to diagnose and inspect your vehicle.
Why does my car struggle to start every 4th to 5th time?
It sounds like your starting issues may be linked to a problem with air metering or fuel delivery. A clogged or malfunctioning idle air control valve may show some of the same symptoms you are describing. The idle air control valve can be stuck in a cold start position which may work well if the car has been sitting a few hours, but as the engine warms up there must be a regulation in airflow. Consider hiring an experienced technician like one from YourMechanic who can come out for a closer look at your hard start situation and offer a more personal diagnosis.
Why does my car start one day and the next day it wont start? The car will crank but wont turn over
Hello, thank you for writing in. With intermittent symptoms, diagnosis can take longer but is typically the same as diagnosing any other starting problem. The main issue is that you can only perform the testing needed when the issue is occurring. If the vehicle starts and works normally, all of the components are likely going to pass their tests. There are several components that will work intermittently. They include the fuel pump, charging system, a number of sensors, and any electrical connection that is loose. When the vehicle is not starting, test for fuel pressure, spark, and the electrical connection on any of the sensors that effects starting (air intake, camshaft/crankshaft position sensors).
