    So i just top swapped my gt, when i try to turn the car on it sounds like im full of misfires and the engine bay fills with white smoke (hopefully from an exhaust leak which i have (i hate you obx headers))

    My thoughts are i ****ed up the ignition wires somehow or the injectors are clogged since i got them from the jy
    And i dont know the signs and dont want to even look it up but maybe head gasket issue

    Front 3 from left to right: 1 3 5
    Rear 3 from left to right: 2 4 6

    Match them up to the cylinders numbered on the coil packs.

    You did write the 36# injector table into the pcm, right?

    Ok we'll assume your injector table is g2g then. How about those plug wires?

    check the compression on the motor. did you have the heads planed so they were flat? type of headgaskets? white smoke is usually coolant...

    Let's get it idling before anything if we can. Does your tach move while you're cranking it?

    If not, double check your ICM and make sure your crank sensor is plugged in. ICM ground, too, sometimes that gets overlooked. And double check plug wires, make sure those are good. If you can toss a couple engine bay pics in we might see something out of place by chance, couldn't hurt.

    your a ways off from me.

    turn the key to run and check for gas leaks and then check for fuel pressure too.
