Engine cranked and turn freely, no start, only code p1000, suspect fuel pump or fuel pump driver module.How to check them?

 

Check the fuel pump relay. When you are looking at the fuse box in the engine compartment you will see 2 large realays at the front of the box. Facing it the small relay on the right is the fuel pump relay. Switch it with the one next to it.
Have you checked fuel pressure at the fuel rack. When you turn the key to the ON position the pump runs for 3 to 5 seconds to charge the fuel manifold and then shuts off. The fuel is then controlled by the ECU once the engine starts.

 

Somehow you've caused the P1000, any idea how? May be a clue what's wrong.

 

Thanks Avern1, I'll check the relay, possible (and hope) it was the relay, be cause the way engine cranking and sound exactly like after engine over heated I don't have the tool to check the fuel pressure, and there is no place to test it, I have no idea what make the code p1000, I have to wait to move the car forward to make room to jack the rear end up to check the fuel at the fuel filter.

 

The P1000 DTC code is a manufacturer specific trouble code. In the case of Ford & Jaguar vehicles, it simply means that the OBD-II monitor testing is not complete. It is a similar meaning for Mazda, which is OBD-II drive cycle malfunction.

Potential Causes Potential causes of a P1000 include: The battery or PCM has been disconnected (Ford, Mazda, Jaguar) The diagnostic trouble codes have been cleared (Ford, Mazda, Jaguar)

 

Avern1, can you tell me which one is the fuel pump relay, with the picture? I try to paste the picture of fuse box but I don't know how!

 

Follow the link below so that you will have a complete picture of the fuse boxes and a numerical listing of each fuse. Just swap out the fuel pump relay with one that is the same size.

Thanks Avern1, but my late 04 fuses box doesn't look like one on the tread. Is there any tread that show how to test the relays?

 

Good day to you. I was traveling for a couple days. I didn't realize you had a 2004 model. Follow the link below and download the 2004.25 electrical guide. Aound page 11 is the fuse box layouts for the 2004 models. You should also find the innfo for testing relays and point testing for the wiring.
