obd0 - obd1 no spark issues
hello, so i've spent all day trying to figure out this electrical mess.
i have a 88 std, obd1 hardwired ( third time converting an 88-91 civic to obd1 ) with an obd1 motor.
so i'm getting fuel, main relay is fine but im not getting spark. i searched around and finally came across wiring your dizzy straight to your ecu. so i wired up :
TDC + B13
TDC - B14
CKP + B15
CKP - B16
CYP + B11
CYP - B12
ICM A21
after doing so, it fired up and held idle.
so then i continued wrapping the wires that i just finished doing (car off/battery disconnected). then when i reconnected the battery to give it a test run, it wouldnt start anymore.
i then spent another 2-3 hours testing the main relay, reconnecting the wires from ecu to dizzy and still no luck. also i've tried my dizzy on my friends gsr, it was fine. tried out different obd1 ecus ( p06 & pr4 ) still no luck!
help me out ! i'm running out of ideas..
also, the IGN output black/yellow wire from the dizzy, i can't seem to locate it.
sorry for the poor writing, really tired and overwhelmed.
