Re: 1997 Grand Prix GTP starts but wont run for more than...
Is this a supper cahrged grand prix if so check fuel pump resistor located behind right front head light or on fire wall its made of white ceramic has to wires going to it jump the two wire on the connection going to it if it runs longer then 15 min then replace resiustor.

has to be corroded fuel pump resistor behind passenger head light under hood but Im sure by now you have done the research and found that out already 97 gtps had recalls because its in an easy spot to get corroded can buy a new kit for 40 bucks or so through gm or online
If you have a GTP these engines use a hi output fuel pump. they use a fuel pump resistor located under the battery tray (look up from under the car) This resistor lowers the voltage to the fuel fump when not in boost mode. because of its locatoin it is prone to corrosion. if you bypass the wires and the engine starts and stays running replace the resistor
yep i seen it in happen .i was at a gas station a guy drove car to the gas station on empty.he fill his tank up .could not get it to crank .some cars you have to restart fuel pump when run out of gas. like chrysler.you use a scanner. but chervrolet you run low over heat damage the pump.it has to stay submerge gas to keep it cool. check fuel pump pressure.it should be 41 - 47 psi.
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.
check all fuses for turn signal and brake lights.change fuel filter . first. do a little tune up change spark plugs and wires . if changing fuel filter dont help. have fuel pressure check first before buying a new fuel pump .they run after taxes 400.00 dollars. your fuel pressure should be 41 to 47 psi. replace fuel pump relay also.
Heres what you need to do to start with. If you are mechanically inclined, when it stalls, check for spark on the #1 cylinder. If you have no spark there, it is likely the CPS or Crankshaft Position Sensor has gone bad, a common issue, and will need to be replaced.
