2003 Pontiac Grand Prix 3800 V6
Dear JK: The car will turn over, run for a couple of seconds
and then shuts off. After about the 10th try it ran fine. My son
says it has been difficult to start for a week or two.
JK:
Hello and welcome,. This could be 1 of several problems. You could have a fuel pressure
problem(bad fuel pump, plugged filter), Leaking fuel pressure regulator
causing a rich condition- which would stumble and chug before it dies, or you could have a
theft system problem. If after it starts and stall, leave key on and see if the security/theft
light stays on or flashes-that would indicate a theft problem. While it is acting up, will need
to check these things in order to find out what is the next step. Let me know what you
find.....
