    So a fuel pump can be the problem even if you can hear the low hum noise?
    Also curious that it can"fix itself" after cooling off.
    Just trying ti confirm your ideas.
    Thankyou

    If the car will start fine and run fine, until I shut it off, then it will not start. After waiting at least 2 hours it starts instantly and runs fine.
    How can the PCM be checked?

  • benchhook Jul 19, 2008

    The terms Electronic Control Module (ref 12-16) Haynes Manual: Power Train Control Manual ( ref. 6-6) Haynes Manual: seem to be interchangeable. Anyway I.m referring to the computer behind the glove box.
    I've had the car towed twice and when it arrived it started and ran fine so they can't fix it if it ain't broken.
    I just let it idle for over 2 hrs cause I'm afraid to drive it any where and it is still fine.
    No engine lights show on the dash.

Well ginko is on the right track but there is a way you can test the fuel pump your self,

1._ open the hood
2. Remove the hose connecting from the gac filter to the injecting system(remove it from the engine
3.) Put the end of the hose in a bottle
4.) TURN THE IGNITION ON
5.) gas should pump from the tank to the filter and then into the bottle.
6.) cut the ignition off and reconnect the hose
7.) double check the connection to ensure its in tight and secured propperly.

If you got the gas in the bottle then the pump is working fine
examine its contents for particles or discoloration
if its clogging it may be the filter you can try pulling the hose from the other end and pump that gas to a bottle and examine it..

IU hardly doubth its the fuel pump , but check it any way. as there might be drags in the tank and its plugging up the system. I personally believe its a senson malfunctioning in which case a garage with an auto diagnost tool will be needed. To find and repair the issue.

Chect the pump relay on the main eletrical fuse and relay panel under the hood for overheating.

    You need to have an autodiagnostic done,, this will find your problem if you believe its in the ECU or a sensor..

    It can be fuel pump, ECU, dirty injectors (or carb problem in carb cars).
    Even if the fuel pump is working , it can be faulty, particularly if it is noisy.
    To test the pump a Fuel pump pressure & volume testing is usually done.
    ECU is the computer that determine Electronic injection, it decides how much fuel and when. A faulty ECU (computer) can cause the same.
    Dirty injectors can also cause problems, but from description I don't think is injector problem.
    Go to a garage and have both computer and fuel pressure tested. The test only it is not very expensive, also replacing fuel pump is not too expensive. Replacing ECU will go over $300 for sure, depending on the model.

    One easy thing you can do is check and replace the fuel filter, even if it is not very likely an obstructed fuel filter can cause similar problems. In any case is very easy to replace and costs a couple of $$.

    PCM is the Power Train Control Module, what controls injection is the ECU. To test the Ecu at a garage they connect the car computer to a dedicated machine, this will return an error code.
    To check electronic injection they connect a flow control sensor to the fuel line, and at the same time they connect the ECU to an external machine.
    This kind of test cannot be done at home due to the special equipment required.

Starts well,runs wellfor five mins but then cuts


My first guess would be the fuel filter. It is probably almost completely plugged.

Suburban stalls while driving after running for 15-30 minutes. After letting it sit for 5-10 min it runs fine for another 5-10 minutes, then starts doing it all over again.


a bad crank sensor can cause this. shuts off while going down road, and will start about 10 min, later with no problems runs fine until it quits again. hope this helps,

Car shuts off while driving


if car shuts off while driving it could be a bad crank sensor. a bad crank sensor will shut car off while driving, then it will not start for about 10 minutes, when it starts it runs fine until it goofs up again. the popping could be the sensor for it controls timing along with the cam sensor.

You probably have some corrosion on your battery terminals. Make sure they are clean and connected good and tight.
