assuming i figured out how to back probe, i'm getting so power to my crank sensor, cam sensor, coilpack or my fuel pump. other then the ecu is there anything else that controls fuel and spark together? i need any long shot here.

any suggestions? and how do i check my ignition? or is my coil and plugs my ignition? i really don't know what i'm askin lol, just what should i tey next. i've read my book about ten times and tried searching as much info as i can. what i really would like to know is that if my car (2g 420a) has a main relay, because i'm pretty sure a main relay controls everything i don't have, except all i can find is that my car has a fuel pump relay (automatic shutdown relay) but from what i've found is that it shouldn't cause me to loose spark.
