Hi my name is Curtis. I am new to this forum. I recently purchased an 03 Grand Prix V6 3.1L. The vehicle has over 200,000 miles but runs very good, well it did. My vehicle has been dying on me while I am driving. The firs time this happened I was making a right turn at a street light when my car died, I coasted into a parking spot and could not get the car to start. The battery had a full charge and car cranked but no start. I towed my car home that night. The next day I tried again and the darn thing started. Don't know how but it started, so I drove to the corner store and back and had no problems starting.
A few days ago my wife was running errands and was on her way home when the car died again. She stalled and had some good Samaritans help push vehicle into a gas station parking lot. She called and I was less that 5 minutes away. By the time I got there she said the car started so I followed her back home.
So I get the car back home and I am thinking the fuel filter is clogged or the fuel pump is going out. So I check for fuel pressure under the hood at the fuel line. Now I don't have the tools to check the system properly. Long story short I have replaced the fuel filter and fuel pump and have the same results. My car still stalls when it heats up it seams. I don't want to guess at what is wrong or replace anymore parts that may not need to be replaced so if anyone has any suggestions or advise I would appreciate your input. Thank you.
