Alright how do i adjust the timing without starting the car? I've tried adjusting the timing. It was running but now it is not. I've checked spark. It has spark and they are in the correct firing order. Car is getting fuel. Seems like i can give it gas and it'll die and when i let off it's like it gets the gas then. I think it's running a tad rich. I'm ka-t running JWT ecu with 50lb msd injectors and cobra maf. Had to swap engine harness's. One plug is off the car... not sure where it goes. I'll post up a pic

This one here it is one the main engine harness. Right after where it comes out of the firewall it splits off from the big bundle. There are like 4 plugs on this split off. Maybe more maybe less. Anyway this one is unplugged. Also it has no rear 02 sensor. so that plug is not hooked up. Not sure if that affects it or not.
