I blew fuse #19 under the dash when looking for a hot wire, now truck won't start. No WTS light,no crank or no fuel pump.

Also swapped ECM's no change.

What does the GEM module control? Would that cause a no WTS condition?

The GEM is the Body Control Computer.

The no WTS is a good indication your PCM isn't running at all.

Check fuses 30 & 22 but, if 19 blew and has been replaced (you're SURE it good now?) then your PCM should be powered-up and it sounds like it's not :(

If you've tried another then, somewhere, you've lost power the PCM needs to run. You gotta find out where the break is....

Ok weird stuff!!! Went out to get something from the truck, and for S&G's put the key in, turned it on and lo and behold there's the WTS light!!! Fired her up and she's running smoother than I've ever heard (maybe it's just cuz I missed her), I jump in and run down the street to get some fuel ($138:(). I take her out on 820 and open her up. Couple things I noticed were the trans is shifting much smoother, motor seems quieter and smoother, and shes quicker, no 6.0 or anything but definitely more than before. I did throw a PMT2 in her, but I didn't expect as much as I got. The thought/question/theory is this time she sat for a couple days, undisturbed, with the batteries hooked up, would the ECM learn or energize? I had put it in the end of last week with no success on starting and I disconnected the batteries. The last time I played with it I said the hell with it, pulled the key and just went in the house and let her sit.

Anywho, just thought I throw an update :headbang1::headbang1::headbang1:
