Question about 1994 Acura Integra

1 Answer

94 Integra Won't Start

Had failed fuel pump. Installed new pump and car ran fine. After short while stopped starting. Checked newly installed fuel pump outside of car with battery voltage...pump runs strong. Re-installed pump and reconnected electrical plug to pump and both ignition fuses blow. Checked the continuity of the fuel pump relay. checks out ok. Checked for short to ground on positive going to pump - no short to ground. What is going on?

If the pump blew the fuses then the pump or the wiring to it inside the gas tank is shorted.

SOURCE: 91 integra not starting

Hi,welcome to fix ya. this could be caused by the main (PGMFI) relay under the dash it controlls the fuelpump . There is a circuit board inside it that cracks and causes the fuel pump to shut off,

SOURCE: My 91 acura integra with a 95 gsr motor in it

did you check the fuel pressur on the fuel rail with a gauge or did you just unplug the pressure reg..

also you should try replacing the fuel filter first... this is cheap 6-12 dollars autozone. just becuase the fuel pump is pumping doesnt mean it its enough. There mightbe a strainer on the fuel pump that might be plugged.

SOURCE: my car starts and runs then it wont go anymore and

I think it's possible that the fuel regulator is stuck open and allowing the fuel to return to the gas tank. If your car is like mine (1991 Acura 1.8 engine), you can try this experiment: Pull the vacuum line off the fuel regulator (it's on the end of the fuel injector manifold and a hose connects to it to return gas back to the gas tank) and temporary plug the hose with a small bolt or golf tee. If the regulator is not stuck open it will make the fuel injector manifold at the highest pressure. Start the car and see if it dies or keeps running ok. If it runs ok then the vacuum control is not working right. If this doesn't help, try changing the fuel regulator valve or pull it out and test it with a vacuum off and on. When the vacuum pressure is present to the valve the valve is suppose to open slightly, this allows fuel to bypass the fuel rail and return to the tank.

seems fuel related--pump and pressure regulator may be failing--a pressure test for residual fuel is needed. Go to an honest, independent or specialist. Injector driver could be going bad. It\'s in the computer. Get a obd 1 scan tool on it to read data as well as any codes

Fuel pump

You would need to check the wiring at the tank to see if the pump has power and ground. Its possible you cooked the pump by running the tank empty. The pump uses liquid gasoline to keep it cool and lubed.

Can you jumper the fuel pump and make it start and continue to run ?
Have you checked to see if you are getting spark when it won't start ?
Could be a relay or coil, ignition module, or other component.

Feul pump malfuntion after stereo installation 94 ford f150 It ran fine when it was parked installed a new stereo and it won't start both fuel pumps seemed to have stopped working..

Check you Inertia switch, known as the crash switch. This can be set off by vibration or impact and all you do is press the reset button on the switch for 3 seconds.
If this does not work check the fuse. If it is not blown check the fuse socket with the ignition on to see if the power is dead to the fuse. If you have power to the fuse then you need to check for power at the fuel pump.

I have a 1990 Chevy Astro van that stopped running on me while I was driving it. I towed it home. I replaced the fuel pump and it ran for a little while and started running very rough. So I bought another...

You say you replaced the fuel pump, what about the filter? If the filter is clogged it can cause this as can ignition. Since the car started for you after the fuel pump was changed the original problem was the fuel pump. But you should never change the pump without installing a new filter.

Check your lift pump. It is on the framerail. If that is not working check your oil pressure sensor it is behind the fuel filter. The lift pump does not get voltage if the oil pressure switch fails.
