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.

 

how would i test them?

 

Unplug ECU connectors A and B. Use a multimeter set either to test for continuity or to measure Ohms on the lowest scale.

 

Ok, ill grab one at work tomorrow. If there is no continuity what would i have to do?

 

There's a broken wire that must be fixed.

 

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.

.

 

Also check whether the 4 injectors wires are properly pinned to the ECU:

 

Ok, ill check them now.

 

injector wires are good in the ecu. You said check for continuity to the body ground? Which ground? Anywhere on the body?

 

Yes

 

Continuity is good. The one for te icm was a little dim but everything had the tester light up

 

My mistake -- I should have written A24 not A22 (corrected). Test A24.

 

24 is good as well

 

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?

 

You said earlier that your injector clips have battery voltage, right?

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?

 

Do not unplug the injector from the connector. Just ground the injector ground wire.

 

I figured it out. The plug with the four Injector wires was all messed up. It's all good and running. Thanks a ton man

 

 

hey mate i'm having the same problem with my 98 ek civic, ive tried everything and was wondering where the plug with the four Injector wires is located pleaxe help thanks

 

Was wondering if you could help trouble shoot this I have 12 volts to my injectors but my ecu is not putting out any signals from a1,a2,a3 or at I've checked and got ground and power to ecu yet no signal for ground to injectors
