95 civic wont start. No injector pulse
Ive got a 95 civic cx with a b18 swap. I am having a no start issue. It has good spark, and will start with starting fluid. I checked the timing and it is good. My ecu is good. Pump will prime and everything but the injectors wont spray fuel. I heard there were ground for the injectors. Where are they? Can they be cleaned. Thanks.

Test for continuity to body ground at A24, A23, A26, and B2 in the ECU connectors.
Do all 4 injector clips have battery voltage with the key in ON(II)?

Oh yeah, forgot to mention, all four injectors have solid 12v on the yellow/black wire. Just no grounding is occuring to make them open.

Where should I test the other side of these wires? I have a continuity tester, I just don't know where the other end of the wires are to test them.

Re: 95 civic wont start. No injector pulse
injector wires are good in the ecu. You said check for continuity to the body ground? Which ground? Anywhere on the body?

Re: 95 civic wont start. No injector pulse
I also see that the injectors get their power from c125 which is that plug with the yellow and black wires all coming out of it right? Could I have possible messed them up while re-pinning my harness? Would that cause this issue?

What makes you believe your ECU is fine?
Unplug ECU connector A and remove the 15A hood ECU fuse. With the key in ON(II), ground one of your injector ground wires. Does the injector make a click sound?

Is there continuity on the 4 injector ground wires between the injector clip and ECU connector A?

I put in a friends ecu, it was a chipped p14 but he said it should have at least started the car. Ill do the test on the injectors in a minute. Just ground the wire that goes into the connector right?
