I have a 2002, Firebird, 3.8, auto trans., convertible with 180,000 miles. Over the years, I have performed regular maitenance and replaced the alternator, battery, tires, plugs/wires, battery and altenator, belt, gas cap, etc.. Recently, I replaced the water pump and intake manifold gaskets. I have a small oil pan leak somewhere. Need to replace original shocks as ride is very rough on rough roads lately. Recently, allowed fuel tank level to get very low before refilling. Overdue for fuel filter change.
Yesterday evening (about 50 degrees outside), the car died while driving down the road. It would not restart. No trouble lights. Wait 3 to 6 hours and car will restart and run for up to 3 or 4 minutes and then die. I am trying to determine what to fix and or replace. I have checked fuel pump and ignition relay switches under the hood and I have checked all the fuses under the hood and on the drivers side panel.
My research shows that it could be the crankshaft position sensor or the ignition module, or the fuel filter or the fuel pump. When I turn the key, I can not hear the pump but the tank is full and it will start if it has sat long enough. What is odd, is that it will start and run and then die after a few minutes, and then restart and run AFTER setting for at least 3 to 6 hours. It will not restart after a few minutes or a few hours, it must be at least 3 hours or more. Some say it could be the fuel pump getting too hot, others say it is a crankshaft postion sensor that is heating up causing a curve in the sensor that straightens out after it cools, allowing the car to start. Yet, others say I could have a huge piece of trash blocking the fuel filter opening when the pump is activated.
This is a daily work vehicle. I would appreciate any assistance figuring out what I need to fix and or replace. Thanks.
