1983 toyota corolla 69,000 miles. Not sure if it’s a problem with fuel lines, fuel tank, or fuel filter.
Only has 69,000 miles on it. It takes it a few tries before it'll crank and when it does crank it smells like pure gasoline. When it finally does crank it'll go for a few seconds and then sometimes stall out. But when it gets going for a few miles it'll be fine and then it acts like it doesn't get any gas and it won't accelerate so I'll have to restart it going down the road. Could it be the fuel tank? Or the fuel lines? I have already put a new carburetor new fuel pump and new fuel filter on it.
Experienced mechanics share their insights in answering this question :
If the exhaust smells like gasoline, the fuel mixture is either way too rich or you have a weak ignition system that is not burning the fuel efficiently. You can pull spark plugs out to check them and if they are wet or black they may be fouled and this can cause very rough running, misfires and stalling. Consider hiring an experienced technician like one from YourMechanic who can come out for a closer inspection of the vehicle in order to run a few tests and offer a more personal diagnosis of your stalling and drivability concerns.
How to Identify and Fix Common car Problems ?

These vehicles are equipped with a Denso low-pressure fuel pump which could cause vehicles to run rough and ultimately lose engine power and stall. Toyota recalled more than 5.8 million vehicles worldwide throughout 2020 and 2021 due to the defect.
Depending on the model year and the terrain you`re driving on, the Toyota Corolla can go between 45 and 47 miles on empty. This is typically more miles than other similar compact models, and it should give you plenty of time to find a filling station.
If you`re considering a Toyota Corolla, you may be wondering, “How long do Toyota Corollas last?” With regular service and maintenance, the Toyota Corolla has a life expectancy of up to 10 years or 300,000 miles. Assuming you take good care of your new Corolla, you could have it for well over a decade.
Fuel pump failures can be caused by electrical faults, old age (wear) or fuel contaminants (dirt, moisture or bad gas). Fuel pump failures often occur without warning. Fuel pumps, injectors and pressure regulators are the three most commonly replaced fuel system components.
Common signs include a whining noise, hard starting, engine performance issues, and an inability to start the car.
The most common cause of fuel pump failure is frequently running the tank low on fuel, which causes the motor to overheat. The second most common cause is fuel contamination, usually dirt and rust particles that clog the fuel strainer and prevent the pump from drawing enough fuel under high engine load.
Noises, backfires, and sputtering engines indicate a fuel pump gone bad. Typically, electronic fuel pumps won`t make a noise unless they begin to fail. An inconsistent fuel flow may cause internal engine problems, leading to hesitation when starting the vehicle or upon acceleration. Engine light comes on.
Toyota Cars Fuel Tank Capacity and Mileage:
The fuel capacity of the Toyota Corolla is 50 Liters. The average mileage of Corolla is 11.3 to 13.4 km/L.
To confirm that your pump has failed, check the pressure in your fuel lines with a fuel pressure gauge; if it reads zero, then your pump is likely dead. You can also check your car`s fuse box; a blown fuel pump fuse is another reliable symptom of a failed pump.
Can a fuel pump go out without warning? Absolutely! A car fuel pump will fail without warning more often than you may think. All things related to a car fuel pumps like the injectors, the pressure regulator, and the car fuel pump itself are the part that are most replaced with the fuel system.
Because fuel pumps constantly run whenever the ignition is turned on, they can eventually wear out and weaken over time. A weak fuel pump may still pump fuel, but the vehicle may experience difficulty starting from the lack of pressure.

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.

I got a 2001 toyota camry. My mechanic was replacing my fuel filter and he broke it where the top hose meets the fuel filter. What
ANSWER : Hi there. Are the gaskets missing, or one of them missing? A missing line gasket for the fuel line at the top of the filter can allow fuel to leak past the fitting bolt and spray dangerously on hot components. Is the leak coming from the line itself or around the bolt that attaches the line to the filter? If the line is leaking it has to be replaced, if the filter is leaking it has to be replaced, and if the leak is coming from around where the line and bolt meet then the gasket is probably missing. If the gaskets are missing or deformed from overtightening they need to be replaced. You may need to contact the dealer to get these gaskets. I suggest having a qualified technician perform an inspection to safely and accurately determine what is needed and avoid replacing unnecessary parts. Your Mechanic has several available technicians that can assist you with a fuel leak inspection.
Car won’t start after sitting for 14 months
ANSWER : Hi there. Check the fuel pump to see if it is energizing, and check the fuel pump relay to see if it is clicking when you turn on the key. If the relay is not clicking, then remove the relay and check to see if there is any power with using a test light. If there is power, then swap the relay out with the horn relay and see if the relay clicks.
If the relay clicks, then the relay went out and needs to be replaced. If the relay still does not click, then check the ground circuit for continuity, which is the feed circuit to the fuel pump. If there is no continuity, then the fuel pump needs to be replaced.
If you need further assistance troubleshooting your vehicle, then seek out a certified technician, such as one from YourMechanic, who can come to your location to determine why the car is not starting and suggest the necessary repairs.
1996 F150 4.9 5 speed. Frt. Fuel pump quit working. Put fuel in rear tank and it sucked the fuel to the frt tank.
ANSWER : The two tanks are designed to work together and so BOTH pumps must be functioning and, as well, the related fuel system supply code, the Code P0232 that has set has to be resolved. P0232 means that the fuel pump relay is stuck on, keeping power supplied to the fuel pump even after the ignition has been turned off although another possibility is the fuel pump secondary power circuit has a short to battery voltage. The factory service manual (FSM) specifies a very lengthy diagnostic (because you have separate tanks). If you do not have the FSM, your best bet is to request a fuel pump diagnostic – dual tanks and let a certified mechanic get to the bottom of this. With regard to the other code, P0704, that code will set if the clutch switch is defective, there is worn clutch pedal lever or clutch lever bushing, shorted or open wiring and/or connectors in the clutch switch circuit, a blown fuse or burnt fusible link and/or, rarely, a faulty PCM or programming error. If you request the pump diagnostic the responding certified mechanic will get this taken care of for you.

To replace a fuel filter or not ? Vehicle had no fuel when bought; added fuel & it started, but should the filter be changed…
ANSWER : Hello, thank you for writing in. Your head is in the right place. While gas these days is held to some better standards, its very possible to collect debris in the tank over time. Considering the mileage on the vehicle, replacing the fuel filter is a great idea anyway, and you should definitely do so. They are quick and easy to do, but you need to be careful with the fuel lines. Also make sure you install the filter in the correct direction. If your fuel pump is original, then you may want to consider replacing it as well. Running a vehicle to empty can hurt the pump. It is also a great time to inspect the tank for debris. For more help replacing either fuel component, contact our service department to schedule an appointment.

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.
