After reading the posts on hear we changed the FPDM but the vehicle still won't start. Don't know what else it could be. Help???

 

What is a FPDM?
I should know but don't.

 

FPDM is the Fuel Pressure Driver Module used on returnless fuel systems.

 

Did you spray starter fluid into the intake to see if it would start?
That usually will let you know if you are having fuel delivery problems (before buying parts).

Did you pull COP to see if it is making a spark when you try to start it?

Watch the CEL. When you turn the ignition key to the on position it should light up. This is the “bulb check”. If it lights, go ahead and crank the engine. If the CEL stays on while cranking, the PCM doesn’t see a signal from the CKP sensor, and won’t turn the fuel pump on.
