I just rebuilt a 90 laser turbo, and it won't start. Everything looks fine except injectors #2-4 are only getting 1.5v and #1 (closest to tbelt) is getting almost 6v from the injector harness.
If I fire each injector by hand with a 6v battery, then jump in and crank it, all four cylinders fire once and then it just dies.
Other stuff checked: -starter runs strong -compression is 80psi across -have spark on all, gap .029 -good fuel pressure in rail -injector harness and plug wires all making good contact -plug wires are connected to coil pack in correct? sequence-(4123 from left to right) -plug wires are within 2k ohm of spec -ecu looks brand new, no cap leakage, plugged in. -known good battery, charged overnight too -MPI and all fuses intact and test good
What do I need to replace? It ran before the rebuild, and I was really gentle on the electronics. Thanks guys

shouldn't it be 180? I would try swapping the coil pack with a known good one and see if that fixes it. I have a spare coil pack that I can get rid of if needed and also have a power tr unit.
