Boost problems

I'm pissed and dont know what to do .My car wont start here is the situation my boomslang harness has some loose pin connectors in the harness which would cause my to car run rough and misfire but if I wiggle the harness the misfire goes away and the car runs fine so we decided to hard wire the fic into the ecu harness but now the car just cranks but won"t start. I even used the fic reverse harness and it still nothing happened .I"ve even swapped ecu"s due to the fact that I would get the same low voltage reading from the factory ecu and I"m not getting any spark from my coils either.Could it be the igniter, or the ground ,or the crank sensor? HELP S.O.S I WANT TO GET MY CAR TUNED SO I CAN STOP DRIVING MY TRUCK!!!!! Boost is a big headache!

what year is your car? I've got a pre-fabbed boomslang fic harness for 98-00 pinout that's practically brand new. If you're using the patch harness with the FIC wires already in, and there are loose pins, it will certainly FUBAR it all. If your igniter is not grounded, that could cause a problem too. The crank sensor should be fine, those don't go bad normally. If it is a problem dealing with the crank sensor i'd be more inclined to think it's in the wiring of your harness than with the sensor itself. Let me know if you want that harness, i'll give you a deal on it (since i'm no longer going NA-T and my car's an 01, i have no use for it)

I would say since your car ran before you decided to hard wire everything make sure that every wire is connected to the right thing. maybe you crossed a wire while messing with them. I'm sure you've already done this many times but sometimes an angry mind misses very obvious errors. So just check all your connects for anything possibly wrong.

I've removed the fic and the harness and plugged in the factory ecu and I'm not getting anything it just cranks but wont start and no spark from the coils .
