(problem fix i got a different ecu)

i just drop my jdm h22 in to my 93 civic hb cx. I'm running a jdm obd1 p13 ecu and its not throwing any CEL. the problem is that #1 is not doing any thing, even though i have spark, fuel, and my compression is the same as 2,3,and 4.

what i did

spark.(using the jdm internal coil)
check the spark at the end of of the spark plug wires, and the plug(check all the gap and switching the plug from a working #(2,3,and 4).also checking the firing order. I also changed my cap,rotor,wires, and plugs with new ones and tried using the old one too.meaning cylinder 1 is sparking but its still not firing

fuel.
check my wiring in the resistor box and all connection is soldered. the injector is working as well(also tried switching the injector from the other ones. also checking the injector plug and it is working.

compression.
using the compression tester in each of 4,3,2,and 1 and all came out with 240 all the way across.

i found out #1 cylinder wasn't working because i pulled the spark plug wire while the motor was running and didn't do any difference compared to #2,3,n 4.

so what could it be?

so you have no spark at all coming from the #1 plug? And also you changed the wires right. Did you ground the spark plug when you tested it for spark? If you did all those things then all I can think of is that the timing on the distributor is off or you need a new distributor.

 

yeah distributor is probably shot...you said no spark in cylinder #1 correct???

there is spark but its not firing.

 

how you know its not firing?? If its not igntiing then you have no fuel. check the injector.

 

yeah you cant really have spark, fuel, and compression and have it not start, your missing something bro.

"fuel.

tired using a different dizzy and ecu(ecu is for AT soo I'm still going to test out a MT ecu tomorrow) today but no difference, still running on 3 cylinder.

 

check the actual injector...maybe its shot....could happen.

same thing i said on top( i tried switching the injector with a running cylinder)

 

got me stumped...bump

 

got my hands on a nother ecu, every thign good to go now. all 4 cylinder running. only thing that i'm not sure baot is i got a 4 plug p13, must of been from the all wheel steering prelude in japan.

 

so it was the ecu?
