2000 Pontiac Grand Prix Repair and Maintenance

A guide to problems, costs, maintenance and repair for your 2000 Pontiac Grand Prix

The intake manifold gasket may develop and external engine oil or coolant leak. In some cases, an internal coolant leak may occur causing coolant to mix with the engine oil. Our technicians tell us that operating the engine  with a coolant/oil mix can result in internal engine damage. Replacing the intake manifold gasket should correct these leaks.

The high pressure power steering hose will commonly leak fluid; it should be replaced.

The transmission pressure control solenoid may fail causing erratic shifting. Our technicians tell us that partial dis-assembly of the transmission is necessary to replace a failed pressure control solenoid.

My 2000 Pontiac Grand Prix GT (3.8)cranks but will not run. I believe it is not getting fuel. I checked all the fuses but I did not check the fuel pump relay. How can I check to see if the relay has failed or if the pump or fuel filter is bad ?

It will start right up sometimes and drive for another 5-10 miles or it wont start for atleast 20 min or so.Sometimes it wont start for an hour or so.I checked the fuel the pressure on the fuel rail and im getting a steady 40 psi. Is this too low and the reason its dying?

My ignition key doesn't completely shut off. I have purchased a new lock cylinder but I am not sure how to change it. Is it an easy process or will it take a while to change?

I thought the car was a guy's car because they have referred to it as a "muscle car". I actually love the way it handles smooth cornering, nice sturdy road car. Maintenance keeps it looking brand new. The only thing is I wish the side mirrors could fold inward.

I bought my GP-GT new in 2000. I now have 107,000+ miles on it. My only complaint has been with the A/C (had to disconnect and use an ideler pully to replace compressor) and the de-fogging function which has always been overpowered in winter w/ very humid/snowey weather.
