Ok, the engine is in, everything is hooked up, and all the wires are where they are supposed to be, but the car wont start, not only that, as soon as I plug in my battery terminal 3 red lights go off on the cluster, one for seat belt, one for battery and one for SRS(airbag) they stay on despite if the keys are in the ignition or not, I have no clue what is wrong, I've tried everything pretty much and same results.
Anyone who went through this, please help.
