Hi, I have a no-start issue on a 2017 LT1 swapped into an older vehicle.
I have done this before with L83's and LT1's with no problems. I have turned off all the usual stuff and done the Write entire (twice).
ECM reads rpm while cranking but no spark on coils. 12v verified in purple wire on coils while cranking.
Hopefully someone have some bright ideas as to why I have no start. Anything I have missed changing in the calibration?
For those interested I found the problem. The ECM was not reading the cam sensor.
The weird thing is that this engine is supposed to be a new crate angine and seems untouched but the cam trigger wheel was too far from the sensor to read. Don't really see how this could happen.
I solved this for the time being by grinding the flange on the sensor a bit to move it closer to the trigger wheel. Had to move the sensor inwards as much as 2mm.
Started right up, but now have new issues with the throttle...
