Your fuel pump relay may be bad. Testing your fuel pressure wouldn't be a bad idea either.

    Check relay, fuel pressure regulator and power coming from computer to relay and fuel pump.

You may have a bad pump or fuel pressure regulator. You will need to pressure test the fuel system.

    If you have the correct fuel pressure to the injectors but the injectors are not releasing the fuel then your problem lies within the injection system. Do you own a scan-tool?

IF BATTERY IS GOOD FOR SPARK THEN COULD BE A FUEL ISSUE, BAD FUEL PUMP WOULD NOT LET CAR START= NO FUEL. WHEN YOU TURN KEY HALF WAY YOU WILL HEAR PUMP GO ON RIGHT BEFORE YOU COMPLETE THE START CYCLE WITH KEY, NO NOISE BAD PUMP. THERE IS ALSO A RELAY THAT CONTROLS THE PUMP . MAKE SURE THAT IS GOOD ALSO

It wont start after putting in new fuel pump was that the actual problem to begin with. how about a fuse can you hear the new pump when you turn key to on (not start) if not then check electrical connections fuse, relay, cam sensor, crank sensor. do that in order i listed it as the last part of that is probally not the problem also is there a fuel shut off valve in this car if so try resetting it.

What's your problem?Hi I have a 90 convertible mustang 5.0. My problem is the fuel pump wont shut off when you turn key on. It runs and runs and car wont start. Ive checked all injectors, changed


Dear Charlie,
May I suggest you take the car to a good (old?) mechanic and have it "changed?".
Right now the fuel pump is hooked to the battery directly, which is why the pump will not turn off.
Please have him hook the pump up so it only runs when the ignition is on.
God bless your efforts.

My 96 yukon wil not start. Sounds like it will crank over but won't. It is not the fuel. I changed the ignition coil still won't start.


try spraying some carb cleaner into a vaccum hose and see if it will run. If so then you have ignition but no fuel delivery. If not then you have an ignition problem. make sure you hear the fuel pump hum when you turn the key to the run position. It should run for +/- 5 seconds then shut off. remove gas cap and listen for fuel pump operation through the fill hole. If you can hear the pump then you have a fuel injection issue. If the engine starts and runs for a few seconds then shuts off then you can suspect the crank or cam position sensor. The fuel pump runs through the oil pressure switch which could also be an issue.

Are you able to start the truck with application of the gas pedal?

Changed fuel pump i put a new battery in changed fuel relay switch and still wont start spryed startin fluid in air hose it will crank and imediatley die? what do i do i have tried everything people...


is the security light flashing when the key is turned on? if so you have a security issue and not a fuel pump problem. the ECM shuts off the fuel injectors so the car won't start. the ignition fire is still good so the car runs on starting fluid. check the light and then email me with more info.
