Carl Eagle Posted December 28, 2011 Author Report Share Posted December 28, 2011 Sorry for not gettin back to you guys, but I had the bcm replaced and programmed to the truck at the dealer. It now will start and shut off after a couple seconds so I put a test light on one of the injectors and it will pulsate and then stops and the truck shuts off. I have to have missed a wire connection somewhere and it is causing vats to kick in like chp said. Where would a good place to find it, around the steering column or elswhere?

chpspecial Posted December 28, 2011 Report Share Posted December 28, 2011 Get somebody with tuning software to turn off vats... if it works then you know that it is not electrical... Quote Link to comment Share on other sites More sharing options...
2001silverado364 Posted December 28, 2011 Report Share Posted December 28, 2011 (edited) http://www.fullsizec...ft-relearn.html A relearn is worth a shot as well, IMO. Do the passlock procedure on that page exactly as it says. Just disconnect the battery for a while to clear the codes on the first step.

Carl Eagle Posted January 7, 2012 Author Report Share Posted January 7, 2012 Ok, I tried the relearn, replaced the cab harness, and it still starts and shuts back off...I dont know anyone with tuning software so I wouldnt know how to get the vats turned off. Do you guys have any more suggestions? Quote Link to comment Share on other sites More sharing options...

Carl Eagle Posted February 10, 2012 Author Report Share Posted February 10, 2012 I finally figured it out. As it turns out the dealer programmed the wrong bcm to the truck. So after replacing all the injectors the cab wiring harness, checking the frame haness and engine harness several times, wearing out a starter, and hauling the dang thing back to the dealer for the second time. After I dropped it off they called me and told me the pcm was fried and would cost almost $500.00 to buy a new one and have it programmed to the truck. I had an extra one and took it to them, the tech said if this dont fix it I dont know what will. So he programmed it to the truck and still the same thing. I asked him about the bcm again and if the part #s would interchange and he told me he didnt know. Luckily I kept the original and found an extra with the same part #, took it to them and it finally started....Thanks guys for all the help.
