Help.... 2007 Expy wiring much needed - no comms, pats, no crank no start etc...

[Mike Expy Poland]

Thank you for the link. Much appreciated! I would buy them instantly, if it would be e-book.. Otherwise it will take me a few weeks till they get to Poland where I am. But I might not have other solution than that. Not a chance you know which wire is this and what is responsible for (a thick, brown red one..)

Solved.

It was a corroded power wire to PCM on pin 8, connector c175B - it was supplying 0,4 Volts less than it should had.. I found it during voltage drop tests. Replaced, and the truck fired right up. Saved myself some serious costs....

Good looking rig, glad to see/hear it's back to a mobile state of being.

Looks really good without running boards, too. What size tires are on?

And a winch?! Ballin'!

Winch comes useful where I live, no need to get a tractor to get out of troubles..., at least most of times. Tires are 33, I raised the car by 3 inches.

Running boards-have no need for them.

Hi - and many thanks. The interior fuse box looks good - checked all fuses, are good. I found this - in the harness that goes between PCM and engine bay fuse box. The location is near the radiator, by the battery. Had to remove battery compartment with washer reservoir to get to that harness.

So the cable fully corroded Anyone knows which cable this is? It is quite difficult to track it through the main harness.

So I had cut out the damaged section, fitted a new one - and no progress.. Unbelievable. I guess I am on the right cable(s)..., I haven't had multimeter today to test it, will test tomorrow..

Is there a good soul that could help me with a wiring diagram of that harness from connector between PCM and engine bay fuse box??? I can read wiring diagrams - it's just that I don't have them..
