I have a 1996 Honda Civic with a GSR swap, the 2 center injectors are not working.

Histroy :

So, i have a 1996 Honda Civic that i GSR OBD2A.

Here is the history on car, Car came with a single cam d15, and a OBD2B dash harness and Engine Harness that was all chopped up so i decided to put in a 96-98 dash harness and vtec engine harness. I dropped the motor in this week and wired up the Idle Air Bypass, Idle Air Control Sensor, Purge Control Solenoid, and C KF sensor. Ran all wires to ECU pins on connectors.

finally got the car running thanks to RonJ@HT . But now Its running rough and 2 injectors are not working.

Also Had a P1298 cel for the ELD but went away after a few restarts

 

Do the two injector clips have battery voltage?

Does the two injector ground wires that run to the ECU have an open or short?

 

If you didn't properly soldered the wires, that is most likely your issue. CRIMP connectors are crap.

 

Yes the 2 injectors have battery voltage going to them and I checked for voltage drop and there is no drop, I will be checking grounds after work today.

 

Ive soldered all injector wiring, so i dont think that is a issue

 

Injectors are controlled by the ECM grouding them, battery voltage is constant. So you either have a faulty ECM, or faulty injectors if the wiring is ok.

 

YOU CAN ALSO USE A NOID LIGHT TO SEE IF THE GROUND IS CUTTING ON AND OFF FROM THE ECU

 

I will get a noid light and try it. i cant seem to find mine anywhere. thanks

 

Sorry been busy with the new born. But i used the noid light and injectors are good.

 

Are the injector clips attached in the correct firing order.

Will the engine start with starting fluid?

 

is there a certain firing order for the injector clips? i didnt know that

 

Injector clips have a proper firing order just like spark plug wires.

List the injector clip ground wire colors for cylinders 1-4.

Will the engine start with starting fluid?

 

i went to go look at it and its way off, its suppose to be brown red blue yellow right?

but its blue red yellow brown

 

and i haven't tried starter fluid, but car starts up and idles bad, sounds like a lawn mower

 

They're out of order:

 

i will re wire it tomorrow since its already 12am here, thanks a lot, i will report back tomorrow.

 

so the car runs a little better but still having issues, when i pull injectors 2 and 3 i still have no change while running.

I rechecked timing and it is dead on. so im back to square one.

 

Do those two injectors spray fuel? Do those two cylinders have spark?

 

they have spark, i will check if they spray, whats the easiest way to check that?

 

Remove the fuel injector and crank engine to watch whether they spray fuel. If so, make sure the injector ground wires properly pin to the ECU connector.

If all is fine, check the mechanical timing and compression test the cylinders.
