Engine is in...I think the fuel injectors are not firing. (Page 2/2) Filben APR 18, 09:09 PM Okay, so I was right, the injectors were NOT firing. It had NOTHING to do with the ECM or the coil or anything like that. I tested the coil, tested the pickup coil, both tested good. So I tried hotwiring the injectors directly through the 6 pin plug and nothing, they would NOT click at all. I pulled one plug off an injector and plugged in an injector cleaner hotwire lead and it clicked just fine on the battery. I checked the wire continuity and it was good. I pulled the intake off and found when I slightly pushed down on an injector lead it would power the injector when it was hotwired through the 6pin plug. The new Bosch injectors are just slightly too tall for the Fiero injector wiring harness to make contact with the terminals! So I dug up the firebird injector harness and it plugged in just fine and fired the injectors when hotwired. So I cut the 6pin off the fiero harness and rewired the old firebird harness and combined them, plugged and bolted everything back up, tried to start it and it got fuel, then backfired a bunch and would not start. Of course the distributor was 180 out, swapped it back around, set base timing and it fired up! It started and ran on the first crank. Theres no coolant in it yet and there a big puddle of oil under it now(I am thinking I messed up the rear mainseal install of course) but that is tomorrows problem. Today the engine finally runs! Thanks everyone!
