    2012 4.8 swap into 71 c10 no start ( no spark ) help!

    2012 4.8 swap into 71 c10 no start ( no spark no injectors)
    Painless wiring harness

    it cranks fine
    scans fine
    has RPM
    fuel is fine
    check my .hpt please see if i missed something (its been a while)


    i turned off all the security that i normally would, but this is the newest ecm I have tried to work with so I don't know if i am missing anything.

    I was reading through the forum i don't know if i read it properly is there an OS patch for turning off security on the newer trucks? and if so how do i do this?

    The VATS is still enabled ... click on the HP OS tab, then set VATS1, VATS2, and Starter Checks to "Disabled". Follow up with a Write Entire flash.
