Archived truck dead 04.5

[Fitchconstruction]

Truck is dead in driveway. Does anyone know of a fuse for the lift pump. I have no fuel pressure @ gauage (manual) and no sound when key is turned. Any help would be appreciated. I've looked at all the fuses and they all look ok.

On my 05 it is fuse 11 and relay 61. 11 is the FCM which I believe is the fuel control module. It's next to the Fuel Heater fuse.



You could try swapping two relays if the fuse isn't blown.

thanks Al. I'll try the relay. Fuse wasn't blown. What scares me is if I rock the key three times nothing is showing up on the dispaly. Over head isn't showing fuel milage either.

Sounds like the Power Control Module or ECM is not getting power.

I looked in my 01 Service Manual. The overhead console has it's own fuse and it is tied to the central timer module. Check the overhead cluster fuse. I believe it also runs the visor vanity lights.



Then you will need to check the ECM connector on the drivers side of the engine. If the ECM does not receive the required inputs, it will not generate the signal to enable the lift pump. Make sure it is seated properly.

I checked all fuses. Truck was picked up and delivered to dealer. This isn't good. Noreastern on the way and plow is sitting in driveway with nothing to attach it to. :{ Spoke to TST and they say module wouldn't mess with ecm I hope.
