Ok hit the fuel tank wile some body keep the engine starting, hit it hard 2 or 3 times, if the car runs ok, the problem is your fuel pump.
replace it.
that happens when you run out of gas, because the fuel pump cools down when gasoline pass thru, if you run out of gas the pump get overheat and goes out, most of the time.

SOURCE: starts and runs 3-5 seconds and shuts down

Sounds like your security system is shutting the car down. You should be able to leave the key on for 15 minutes and it will reset itself. Make sure you are using factory keys, and they are in good condition.

Sounds like air in fuel line. Purge fuel line. By "crank", do you mean engine spins but won't catch? Try starter fluid in intake.

SOURCE: my car starts but after a while dies waht can be

Hello! You're symptoms sound very much like a common problem associated with the fuel pump resistor. The GTP engine has a two speed fuel pump. There are two relays that control the fuel pump via the PCM module. The fuel pump relay and fuel pump hi-speed relay. Tied into the hi-speed relay is a fuel pump resistor that may go bad.

Symptoms vary but primarily the engine will start but die in a matter of seconds due to insufficient fuel pressure.

Here is a picture of the relay - which is located in the fuse box in the engine compartment:

What you can do to both diagnose this and either narrow it down to this or disqualify it as the culprit is remove relay #15, and bend out the tab labeled "85", and then reinstall the relay. If this does solve your problem, then you need to replace the Fuel Pump Resistor. Doing this will bypass the resistor, and place the fuel pump in "high" speed mode at all times. Once you have replaced the resistor, you need to bend the tab back to its normal position and replace the relay.
NOTE: while this may be a helpful diagnosis tool, and provide a temporary fix - doing this procedure for a prolonged period of time can lead to fuel pump failure. Use this at your own risk.


Hope this helps and good luck!

Known GTP problem.

You most likely have a bad fuel pump resistor, which controls 2 speeds of the fuel pump.

To check to see if this is the problem, there is a trick you can do and its very easy to do. Go to the attached link, and bend the tab my finger is pointing at and then plug it back in. If your car starts and runs fine, well we just solved the problem.

I have a 1997 Pontiac grand prix supper charged GTP I believe i ran out of gas and I put gas in it and it didn't start so my mechanic said I flooded the fuel filter so he changed iit but now it starts but...


Its more than likely the fuel pump . Giving the year and the symptoms . You may have not ran out of gas in the first place it may have actually been the fuel pump . You are probably just getting enough gas in it to start and then cut out right away.

1998 Pontiac Grand Prix GTP Starts and turns off approx 5-10 seconds after starting.


I would replace the TPS sensor. If you have fuel pressure enough to start the car, then you probably have pressure always. Before turning the key to start, turn to ON. You should hear the fuel pump pressurizing the lines. Turn the car back off. Go under the hood and remove the cap to the Schrader Valve. Use a rag to catch any fuel when you depress the valve stem. If fuel comes out into your rag, you should have pressure. Try this a second time to be sure. I had this issue with my car shutting down. TPS sensor replacement fixed it. BUT...it could be vacuum lines, or another sensor fault. The TPS is a common issue. You may also want to clean your Mass Air Flow sensor with the proper solvent and technique.

2004 Pontiac grand prix gtp won't start- fully


You need a new starter solenoid. It is essentially a heavy duty remote switch that is activated by your ignition key switch. The solenoids get stuck or don't conduct well after 6 to10 years.
