so i have an s14 with a s13 blacktop sr with a power fc ecu.

i havent driven it a whole lot in the past couple weeks, so last week i started it, let it warm up and run for a while, then turned it off. no problem.

a couple days ago, i went to take it out, and no power what-so-ever. batterys dead, no big deal. well when i went to jump it, i hooked it up correctly, but the ground slipped off and sparked on the battery post. no good. it blew a couple fuses, so i replaced all of those and everything turns on fine and lights up.

well after i fixed all that and went to jump it again, it cranks over fine, has fuel, has compression, but ABSOLUTELY NO SPARK WHAT SO EVER. i found a dead relay replaced it, checked EVERY FUSE and they all checked out.

plugs keep fouling, plenty of fuel, but checked for spark and....nothing. absolutely no spark..

please help, ive checked pretty much everything. is there anything else that could have blown causing no spark? ignitor? CAS? ECU?! (oh god i hope not...) anything that would cause no spark? please, i need to figure this out.

check ALL the main fuses, esp in the engine bay, esp the main big fuses, then check the harness for power, i would suggest pulling the power fc out first and check their, the power fc is a bit delicate sometimes... they burn out ALOT! maybe plug in a stock sr ecu,

goddamnit, i really hope its not the power fc. the commander comes on and shows all my readings and settings though? does that mean anything as far as it not being blown?

did you pull any codes from your ecu? Also, have you checked your ignitor?

driftSTL · 11-25-2009, 11:54 AM

did not pull any codes. and no thats what i need to check next. every fuse has been checked, but just for shits and grins, what fuses would matter most to the ignition? i know theres one in the kick panel, but is that it?

Check your fuse and relay in the relay box(driver side, right beside the battery)...
