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?
