okay so i just got done putting an s13 redtop SR in a s13 i hooked everything up fine, tiger racing did the wiring harness so there should be no wiring problems, well i went to go start the car but it wouldn't start it turns over but won't start, so i started thinking it has to be no fuel or no spark, well i smell fuel so first think i checked for was spark, well i wasnt getting any spark, so i replaced the ignitor with a Q45 ignitor, well just to be curious i was going to check and see if the injectors were pulsating while the motor was turning over, well the injectors weren't pulsating, so i was just standing there looking at the cam angle sensor while the ignition was on, so i reached down and unplugged the CAS and when i plugged it back up the injectors were clicking. WHATS GOING ON??? Is i the CAS that is no good, because the wiring should be fine!!
HELPP!!!:wtf:

yeah i'm thinking CAS also or CAS wiring. as i know for a fact if you unplug your CAS your injectors don't pulse. i know this because that's how i primed my motor the first time i started it up. the CAS obviuosly would cause the coilpacks not to fire either.

look up the CAS testing procedure in the FSM.

well when i unplugged it i didnt hear anything but when i plugged it up the injectors started clicking for few seconds and stopped, but when im trying to start the car there are no power to the injecors and they aren't fireing.
thanks!
