    Scan for codes it can be anything electrical if you have correct fuel pressure. I wish I. I had the light codes read put the EGR valve and O2 sensor on it reset the light and it came back on after a short drive or 2. Just replaced that. Going to need more info, Is it a crank no start when failing, if so you are going to have to see what is missing, spark, fuel, injector pulsethat will give you a direction to start diagnosing.

    If the car "cranks" it is probably not your battery and more likely a fuel related problem. When you put the key in the "on" position before.Then maybe a week ago, it wouldn't start at all.

    Remove the harmonic balancer and check if the crank sensor is loose and hitting on the balancer. Check the balancer vanes for being bent or.Please refer to CarGurus Terms of Use.

    Basically you are just bypassing the input to the starter relay from the pcm. The security system is still disabling fuel, that is why the.I have a Grand Prix GT that is getting fire everywhere and turning over but it wont run.

    I have a GRAND PRIX the problem with it is that it has trouble starting. At first I thought it was the fuel pump and crank sensor but a.I think you should ohm out each of the injectors to see if one stands out, then disconnect that one and try to start it.

    It always starts with no problem and the car is well maintained. There are a few things that could cause this issue. A bad fuel pump, ignition.It needs enough compression to run well.

    Regardless of whether you tackle it yourself or have a mechanic help, though, the more diagnostics you can do on your own, the better off you'll be.

    Then an hour later it may do this again or it may start right up like nothing is wrong with it.

    I have 50 psi at the fuel port gauge attached so fuel pressure is not a problem and it does not leak down.
