2002 Pontiac Grand Prix fuel system problems

Filed Nov 5, 2026 · Electrical, Engine · CA

I took my 2002 Pontiac to Thompson Chevrolet, located in Patterson, CA., for a recall that was not needed since the engine was rebuilt. My car had no issues and was operating just as it was when first bought. It was running excellent. On March 20, 2025, after I got my car back I noticed my gas gauge going up rapidly and not reading accurately. My car was also not accelerating as it was before but hesitates and jumps as it changes gears. It also has a small oil leak since I got it back. I complained to them and have reported this to the Better Business Bureau and have gotten no positive results. My car can pass a smog test, but, it has an oil leak, the gas gauge is not working since they worked on it and it hesitates upon acceleration. All since March 20th, 2025. Can you help me with this problem regarding the authorized dealership.

On May 27th 2023 just three days ago I went to start my car but it would not start, I tried two times then I smelled gas so I let it sit over night then the next day my friend went out to start it for me and it made a loud bang and the intake manifold exploded causing a fire and debris went everywhere, my is lucky he got away from the when he did or he would have been injured maybe even killed from the flames. I did not take any photos or report to anyone, a neighbor heard the load bang and came out to see if anyone was ok. There were no warning signals that appeared to my knowledge. There were 200,000 miles on the vehicle at time of the incident.

My car wouldn't start so I called aaa. The man tried to start the car before he attempted to jump it. When he turned the key, the car exploded and caught fire. Thank goodness he hadn't opened the hood because I was standing next to the car and could have been killed from the flying debris. When we opened the hood to put out the fire, the intake manifold was completely destroyed and in pieces. I ended up having the car towed and they replaced the intake manifold and the fuel rails costing me $900. Yesterday I went to start the car and it acted like it didn't want to start again but finally it did but I did hear a pop. When I researched the problem online, I found an article about chevy impalas exploding but from reading the comments, it appears this is a problem with all gm cars from that time period. I'm linkng the article so you can read the reviews and can see that this is still an ongoing problem. The opening comment explains that there was a previous recall about this very same problem in the late 1990's. The problem is with defective fuel pressure regulators. Everything described is exactly what happened with my car on february 6 of this year. I now know I need to have the regulator replaced or it might happen again. I'm a senior on limited income and I can't afford this expense, especially when it's a problem that should have been fixed with a recall. Unfortunately, I didn't take any photos of the incident but I have the repair bill and I'm sure I could get a statement from the aaa person who was also present when it happened. Here is the link for further testimony showing someone wrote as recently as february 12 with the same issue.

My 2002 pontiac grand prix with a 3.8 liter engine caught fire while I was out of state in detroit doing training for work. I parked at the hotel I was staying at after a short trip to dinner and back I park my car and 15 min. Later I heard two load pops (noise was front tires blew out because the fire got to hot) and looked outside my hotel room and my car was on fire and a co-workers car parked next to my car caught on fire there was hotel damage. Plus two cars totaled and no way home. It sucks! There was a recall on the car involving engine fires. I took the car to a gm dealer and had the recall work done a year ago. Nice work gm!

This is for the gtp supercharged model. Replaced the fuel pump and now all of a sudden leaking out of shrader valve above the injectors which is was not doing before. Online says there was a delphi fuel pressure regulator recall but after entering my VIN says no recalls. Although I also took it in last year due to the recall concerning oil dripping on the manifold and causing possible fire so unsure why it said no recalls.. I will attach photo of website claims. Any help in this matter would be greatly appreciated. Thank you
