Yep fuel pressure, fuel in the rail, spark to all but the 3rd cylinder now and everything else works in the car. I'm thinking either A: the ECU fried, B: ECU/Injector ground bad or C: cam sensor. I think one has to be the problem, maybe all IDK. No spark on 3rd cylinder also now, my cap and rotor are burnt a little. The reason I say cam position sensor is the motor needs either a crank or cam position and JDM motors have a cam not crank. It needs to know where everything is for the duty cycle to know which injector to open. The cam position sensor is located inside the distributor, maybe something fried hence the burnt cap and rotor and 3rd not sparking and maybe it burnt up the sensor? How should I check the ECU to make sure its grounded? Before I go buying a bunch of things I want to try and check everything to see exactly what needs to be replaced.
