Welp finally finished this swap up, went to start it up and I don't get anything. It's doing several different things..

At first, on a full battery charge, fuel pump would prime, starter solenoid would click but no turnover.

Seat belt, brake, and door ajar lights in the cluster are BRIGHT, but cel, battery, and oil lights are dim as hell.

When I jump the two terminals on the starter it has an extremely low voltage and I hear a slight arcing sound coming from the fuel injectors.

I unplugged the fuel injectors and the cel, oil, and battery lights in the cluster go off.

I leave next week for six months and the cars either going in storage or I'm I'm just going to sell it as is if I can't figure this out.. all help and input is GREATLY appreciated!
