Customer tow in, 2000 6.5 TD with dual tanks. No comm with scanner so proceeded to check out fuses. Found 20 amp fuse to ecm/fp blown. Checked Mitchell for wiring diagrams but they have no information for these models. Replaced the fuse and all is well...for the moment.


Anyone know where the problem might lie or where to get a schematic for this system? Thanks

 

Does the fuel pump work? If I remember right the OBD2 power is supposed to come off the cigarette lighter circuit.

 

The fuse is designated as fuel pump/ecm on the legend in the fuse box cover. As I posted previously, once I replaced the fuse it ran fine. Pumps seem to be internal in tank.

 

The The fuel lift pump is not inside the tank. Normally the fuse blows when your fuel pump burns up. It will still start when the lift pump goes bad. Do you have fuel pressure? Are all the ECM ground wires connected to the proper locations? where are you located at?

 

Hmmm, I will get under it this morning (too wide for floor post lifts) and look for lift pump. I'm assuming it's forward of the tank selector valve.


I'm in Taos NM.

 

Just call me. I can help you out over the phone

 

Lift pump is in front of the driver by the firewall.

 

Thanks all, got a pump put in it and sent him down the road.

 

From our conversation it sounded like your doctor customer needs some hummer love. I hope you sent him UP the road to my brother @ Big Dog Offroad(bigdogoffroad.com) in Golden,CO
They only work on hummers (H1 & HMMWV only)and seem to get there sahre of the east coast trucks that have rust issues like that one.

 

Gave him your info as well, thx
