my son and I swapped a b18c into a 1996 civic ek. everything is hooked up but I"m not getting spark or fuel. I have checked all the grounds and replaced the main relay. we are using the stock wiring harness as the original motor was a y8 vtec. any suggestions are greatly appreciated.

 

the thermostat ground?

 

Yeah checked that already. Someone said I might need a third ground from the valve cover to the body.

 

What ecu code? jdm or usdm?

 

Usdm

 

is it obd2a or obd2b?

 

Obd2a

 

Your civic is an obd2a, you need an obd2a ecu. Another thing to check is that thermostat ground because it provides a ground for the main relay and the ecu to prime fuel and let the ecu fire the injectors.

If you're not getting spark you need to find out why your harness isn't powering the distributor.

 

Ecu is obd1

 

Were using a jumper

 

Try another ecu.

 

Have tried three different ecu's lol

 

You didn't state that lol

 

I apologize for that. I also wrote ek in the original thread it's a ex sorry

 

so what else is missing LOL.

 

 

We sorta figured it out. It was the main relay. But the jumper harness we got was obd2b to obd1. We hooked up the original ecu directly to the car and started, but like crap lol. My son is getting a p73 Obd2a spoon ecu for $100 bucks. So that should solve everything.
