Hello, first post here. I bought this car, and need help to make it run.
2002 grand prix 3.1, ran great, parked for 10 minutes, and wont start since, so my friend sold it to me for a good deal.
the fuel pump is not turning on, so no fuel pressure, and their is no spark ( I used my timing light to check, numerous times to be sure). and now the gas guage reads full to the max.
It ran great and then wont start since. Starter is turning it over great, spins freely.
I assume not a crank or cam sensor issue due to no fuel pump too,
I assume that it is not really fuel pump/ relay related due to no spark.
I assume not a IGN issue due to it turns over great, key works great.
Fuses are good, Hoping this is a common problem. Searched, but did not see anything to help.
I build other kinds of hot rods, and the last GM car I had was my GN that i recently sold after 12 great years. Now I do VH45's in 300ZX's, and SHO's in RX7's. I appreciate the help.
I do not know much about this GP's ECU system, but I assume that it is an ECU problem or a sensor situation through it, that would cause it to not turn on FP, and Ign Sys.
Thanx for any help, Craig
