Thread: UPDATE:::cylinder 3 will not fire :(

this has to be a small stupid problem. lets see, to go over things i have replaced and checked....

multible sets of plugs and wires, 3 dizzys, new caps and rotor buttons, checked continuity and voltage in wiring harness, changed ecu's, same daughterboard with basic tune, checked injector to make sure it was squirting fuel and it is....hmm...

i hope you guys understand that i am super frustrated with this situation and i know you guys are trying to help out and i really appreciate it tremendously. I have never been so confused on this stupid car lol.

This set up ran perfect in my b13. the only thing different is its in a b14 now with a conversion harness lol

You forgot to mention the CAS sensor inside the ignition housing? Right?

yes i forgot to mention that, but i did take one of my dizzys and used it on a friends se-r and it runs his car perfect so wouldnt that rule that out because it would not make sense to run on his and not mine lol

lol

FML! lol

going to change that injector again...

now if that injector is bad, would it cause no spark as well? I have never heard of that before but i guess anything is possible.

I searched google and found a thread that was just about the same as mine and he ended up having a bad injector and his was cylinder 3 as well and he was not getting spark either. Im going to try this.

did a voltage test on the dizzy plug....are all of the connections on the dizzy plug suppose to have voltage? also tested the ohms on the injectors and got 12 on all 4 injectors. I also pulled off the rail again and turned the key to the acc position where the fuel pump primes and no fuel leaked out, and i also cranked on the engine to see if all 4 injectors were squirting fuel and indeed they are all 4 working.

this dizzy plug, can someone confirm to me on weather all 6 connections are suppose to have power or what?

blah...so on the dizzy plug, the white with red stripe wire has 11.2 volts, the black with white stripe has 5 volts and the solid dark blue wire has 5 volts....these 3 are the only ones that have power on the plug and also i was tugging on the plug to see if maybe one of the pins wasnt in all the way and the fuel pump started to prime again and if you keep tugging on the harness right there, the pump will keep kicking on.

i plugged the dizzy plug back into the dizzy and started the car and of course its still only running on 3 cylinders and totaly missing number 3, and tugged on the harness and the fuel pump kicked off.


do you guys think there is something going on inside the harness and i need to split it open and look at all the wires?

5 Volts? Could there be TTL logic inside there then?

im about to cut the loom off the entire harness and see what is going on in there.
