Help Needed 6.0 sudden no start.

If I can get it towed to work tomorrow and figure out how to close the ipr I will do the air test. Thank you gentlemen.

Well I left the pos plugged in all night and it fired right up this am.
So I get to troubleshoot the GPs now....

 

[The Extractor]

found the prob. stupid PO put an accessory wire of some kind under the GP post (it was cut off) on the battery terminal and it had corroded so they werent getting power.

U have to be careful where u grab power from on these trucks, i've heard of people who were having problems with the tranny shifting and it was caused by some accessory was hooked up incorrectly

 

[The Extractor]

the wire was cut and only an inch long and I never gave it much thought...

 

[The Extractor]

well that wasnt it. It has continued with intermitent no starts. I would wiggle the GP harness and most the time it would start.
I ripped apart the GP harness and found a bunch chafing and all the wire were "almost" melted together,
kinda like 4 flat trailer wiring almost fused together.

Chaffing was a common problem in 2003/2004 so I am not surprised. Good going!
