Where is the fuel pump resistor on a 1999 gtp?

It may be the fuel pump relay.

No.
The only pump that will work in a GTP model is the pump for that model. And there are more than one tag number for the GTP.
Flow rates can be anything between 20 and 60 GPM.
You have to match the tag code for your car.

main fuse box in the engine compartment .. make sure battery is dq'd or it will short out the new one .

When you replaced the pump did you check the fuel pressure with a gauge ?

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!

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

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.

i HAD THE SAME PROBLEM WITH MY 2001 GTP. REPLACED THE PUMP AND FILTER STILL A PROBLEM. FINALLY REPLACED THE FUEL PUMP RESISTOR LOCATED UNDER THE RIGHT FRONT FENDER, NO MORE PROBLEM.

check the fuel pump and lines. look for the fuel filter and see how much junk is in it.
