Customer brought me a 2010 truck
No start
it has DOD and variable cam physicaly deleted via enging built.
5pin connector is loose at the back of the motor
no variable buisness to plug into at the timing cover
?do the conectors need to be plugged in?
?do certain DTCs beed to be left on or turned off?
Cranks but no start
-has fuel pressure
-has spark
-PCM commands PW at cranking
-PCM works great in another truck
-good voltage at the coil harness
-all fuses check good
2010 4x4 1500 6.2Liter 9.2:1CR large heads and cam Whipple charger
Note:
changing cranking AFR has no effect on cranking
changing the crancing advance makes it almost want to hit
