Dear fellow Zilvian's,

Okay so i just finished my S13 SR20det Blacktop with J4 ecu and wiring harness. I finished and turned the key and nothing. my fuel pump turns on and it cracks but not starting at all. I know that the j4 blacktop wiring harness as some different colored wires at the 2 plugs next to the battery and i'm not sure if i wired it correctly. Anybody that wired this up before with the OEM j4 harness and ecu can to please tell/show me how you did this please?

what do u mean it cracks? turns over? i would check the grounds, then move to starter signal wire. sounds like u have ignition power but its not reaching to ur starter (if its not turning over) but if it is make sure u have power to ur ecu first.

Verify the CAS / timing is 100% perfect.

Okay so I figured out why it wouldn't start. I didn't have my ignition coil wire wired in correctly (blue w/red stripe) so I wired it in with the main ignition wire (black w/red stripe) and it tried to start but no dice. So I replaced the old spark plugs with new ones and it started and runs great.
