2000 pontiac grand prix will crank but not start, have replaced fuel pump, fuel filter, no codes
Would start stall out at various times, hard to start various times, replaced fuel
pump, filter, replaced throttle sensor mass air sensor, etc. i have no idea of
where to go next.
Your GTP (Supercharged) model has a fuel pump resistor behind the battery in the passenger's side fender. These frequently burn out. Does the fuel pump run for a few seconds when you turn on the key (but don't crank it)? If not or if you have poor fuel pressure that resistor may be the culprit. HTH. -Jim
Fuel pump runs and engine turns over, doesn't catch & start. I apologize, I hit wrong thing it is a GT, not a GTP, is the fuel pump resistor in same position in the GT model, & will that peticular issue show no code when scanner is hooked up? Thank you for answering, We are at a loss, & need our only transportation up & running, please
The GT doesn't have the resistor. Will it run a few seconds if you spray starting fluid down the throttle body? If so it's a fuel problem. Have you checked the crankshaft position sensor? They're troublesome. HTH. -Jim
Could be problem with your injectors. If one shorts out, it disables 3 injectors. Stock injectors have been found to be defective. I replaced mine with replacement, non-GM, injectors and solved the problem.
