Question about 1998 Pontiac Grand Prix

1 Answer

1998 gtp grand prix, engine light came on and the car started to

As soon as my engine came on the car started to spudder while driving and is realy under powered. When I give it gas the engine starts to flash but still hesitates. The car has 128,000 km and I just drove it to northern British Columbia where there is quite the difference in altitude about 2200 ft, I dont think that has anything to do with it

    i have a 98 grand prix and this happened to me...i had to take it to a mechanic and it was an gnition switch that wasnt sending enough voltage to the fuel pump. However it could simply still just be your fuel pump.

Try new spark plugs. You can run autolite 605's, inexpensive fix.

    I assume you mean that your check engine light is flashing? That indicates the engine is misfiring. You need new spark plugs.

1998 Pontiac Grand Prix GTP 3.8 supercharge, Automatic Transaxle - 4T65-E rebuilt 2 years ago. Drove to work (26 miles) and all was fine, got in to leave and put gear selector in drive or 1st and nothing...


Your transmission for the GTP should be the 4T65-HD. If in fact it is not then that could very well be the problem. The 4T65-E is for the other 3.8L naturally aspirated models.

New transmission


The best place you'll ever find parts and service for the GTP is www.zzperformance.com

They have their headquarters garage and then several authorized satellite locations in a few states. They make their living on working only with the GTP exclusively.

My 1998 grand prix gtp cut off today while driving it. car still has power battery is not dead. alternator still good and the car will not start. it will turn over but wont quite fire up


my 1998 grand prix does the exact same thing. It just shuts off while driving. I still have battery power. I have called pontiac dealers in my area and they dont seem to have any idea to fixing without changing everything in hopes the hit the problem
Can you narrow it down.

97 grand prix gtp starts then immediatly dies


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
