KA24DE - No Spark, No fuel prime, No CEL, but have power to ECU

[ShayMK]

Hey guys I've been searching for days and have tried mutliple things and still can't figure this thing out..

I have a 89 chassis with a KA24DE I am dropping in. As title states I have no fuel pump prime, no spark, no CEL but seem to have 12v at the ECU. I also have a spare ECU I plugged in and does the exact same thing so I don't think it's the ECU. At this point I know it's going to be something stupid.

I have added grounds from the chassis to motor and battery to chassis so I don't think there is a grounding issue. I tested for power at the Coil and distributor as well and they are reading 12v. I also jumped the EGI pump relay and my fuel pump does prime with the key on constantly until I either shut the key off or take the jumper out. But still do not have spark.

I am at a loss, I have searched for multiple days and cant find anything that I haven't tried. Is there maybe a hidden plug somewhere? Any advice would be greatly appreciated.

Thanks!

Also I cannot get the ECU to do diagnostic mode when I turn the screw on the side of it, the LED doesnt flash at all.

Motor grounding and harness grounds are two separate things.
You may need to start chasing wires via the FSM, tracing all the grounds

I've had an issue like this before and the MAF wasn't getting signal/power from the ecu.

Is it s14 or s13?

Thanks for the response.

I have all the harness diagrams from the FSM and made sure they're all grounded but I will check them again.

And its an S13.
