I've got a 91 Chevy Lumina Van with a 3.1 Liter Engine. The Van starts sometimes and will be ok for a few days and then won't fire. It will crank but not fire. You can hear the fuel pum come on for a few seconds and then turnm off when you turn on the power to it without cranking it. My daughter ran over a large rock in a driveway this past summer and tore a wiring harness in two which caused me to replace the computer, the alternator, and the a/c unit. Just lately I replace the computer once more, the fuel pum solenoid, and the fuel pump itself. It ran for 3 days and won't start again. My brains is tired. And my aaarepair fellow is clueless also. HELP!
