Problem with starting the engine after rebuilding heads
I came across a weird issue:
just had heads redone, now trying to fire the car up, it shows up like this:

and it doesn't want to start although I can hear the starter working
When I connect a diagnosis tool, the gages show like this:

and the car start up normally.
No codes are thrown.
Any ideas?
All three grounds were connected in a way they were before (2 to one bolt, 1 to another).
We'll recheck them.
Is there somewhere a diagram of pins on the ECM connector?
Somebody told me to check the voltage on the ECM as it may be causing the problem too.
