1992 Chevy Lumina Euro


#1

This vehicle in the past year has developed an annoying habit. After being driven for awhile and then shut off, it will not start again for 3 hours. I have replaced the fuel pump and the ecm, still have the problem. Can anybody help?


#2

This is the 3.1L engine, right? Also, define “won’t start”. Do you mean it cranks but doesn’t fire or doesn’t turn over?


#3

Yeah, 3.1L v6, engine cranks but will not start for 3 hours. You can almost set your watch to it. I had the coil pack tested as well, 3 times. It acts like it is not getting fire to the plugs
