Old engine was running normally until it threw a rod.
3.8L reman engine. Compression on all cyl 140-160 psi so no issue with long block.
New plugs and wires.
I would suspect coil pack but 1-2 are not on the same coil (2 on top coil. 1 on middle).
Obviously runs rough. What would cause 1-2 with good compression to not fire? Do the 1-2 injectors work off of the same driver?
Checking injector currents this afternoon.
