Pulled codes off OBT-1 by jumping pins on the connector and reading the ck eng light. Had on code that said something about voltage to fuel pump was low. Replaced water temperature sensor--no luck. :sick: Dropped tank, installed new sender and pump. Also installed new fuel lines and filter while I had everything apart. Same issue. Cleared codes, finally got engine started and rechecked codes..no codes. Oh yes...also checked timing.
Any ideas from anyone?
I am at a loss myself. I have searched on boards for months and still not been able to get a specific answer or find a specific problem. I am definitely at a loss myself, usually it is related to a direct issue but I cant figure it out. :confuse:
P.s. while checking the wiring I did get it to fault and the currents were good.

not able to find any thing unless the truck do that in shop?
I'm currently having the same issue, started behaving that way 1 year after purchasing it. I have the sierra 1500 4.8L model 4x4, the problem is currently live and I disconnected the battery 1 hour ago, I have yet to reconnect it and give it a try to see if it will start.
Verrrrry annoying, you never know when it will strike, no mechanic ANYWHERE ever found the problem!!
