LG/B is "light green w/Black stripe" as the letter L by itself means Blue.

Where did you get this emission harness from as both S4 and S5 have the same injector wire colors?

florotory

the harness is the one that came with the car from the factory. the car was my dads who never did and mods to it. he had it since new.

Just checking but how many wires does your smallest ECU plug have as it should be eight in number? Does pin 3H and pin 3F have battery voltage w/key to on or did you already state they don't?

florotory

ok i was just removing my UIM and noticed my vaccum line to the master cylinder wasnt hooked up and was not capped as well. Which if im thinking correctly would be a big *** vaccum leak thus causeing it not to start. is that correct?

Good catch.

could be but i would think the motor would still start just not idle while ur UMI is off check your injector plugs as per the FSM depending on the year of harness

florotory

yes they do have voltage

rx-7 obsessed

yes if you have voltage check the injector plugs im at work and dont have my FSM handy

So of the 4 injector ECU wires only pin 3E has none to very little voltage?

florotory

correct. and just went and looked at my wires for my injector plugs and they do not match the colors listed in the fsm. like i said i am 100% sure this is the factory harness

florotory

im pretty sure though i have the injectors pluged in to the correct injector

When you tested for voltage w/the ECU plug removed did any of the other three ECU injector pins have voltage w/key to on?

florotory

yes 3 of the 4 had voltage with key "on"

I don't think there is a relationship but how about disconnecting the CAS plug at the CAS and recheck pin 3E for voltage w/key to on one more time and check for voltage at the other injector pins as well to see if there is a difference.

florotory

ok ill do that now.

also according to the FSM one of the wires on each injector should be Black/yellow that is not the case on mine. dont know why

florotory

ok well i was using my test light on the injectors and noticed the front primary wasnt lighting up. so i pulled the plug on it and somehow the pins in the plug came out. so i took it apart and repinned it and new it wouldnt run but figured id see if it wanted to and sure enough it started for about 1-2 seconds and died (cause no maf,UIM hooked up ect). so now im at a crossroads. do i put the UIM back on and try to start or is there more troubleshooting i need to do under there first

The car won't run w/o the AFM hooked up unless the fuel check connector is jumpered but I am not completely certain about that.

florotory

well she runs. boggs a little but i gota adjust throttle cable, retime it again cause i moved my CAS a little. but im a dumbass (obviously) and didnt tighten down all the bolts on my fan and i bet you wont be able to guess what happened? but as of now it is running (fanless) but it seems the injector plug was the problem. thanks to everyone for theyre million replies helping me

rx-7 obsessed

glad to hear it runs hope you checked all your injector plugs for the same problem before re assembely

florotory

Oh I deff did. I greatly appreciate all the help. I would still be troubleshooting. Looking at some of my post the answer was there. I mentioned many times it has to be a fuel issue. Lol. But credit goes to you guys definitely. Still got to get it running perfect. Still stalls when not pushing gas peddle. But that's probably throttle cable not adjusted and intercooler piping leaking a bit cause I have crappy clamps

Sabora

This is happening to my fresh rebuild as well except we have to push start it I think to get it to start up for a few seconds...

florotory

Check MAF
Check Fuel
Check CPS
Check check injectors
of coarse vaccum leaks

florotory

yes i deff checked all injector plugs

Sabora

Well its seems I get good comp...no vacuum leaks to be known based on a Hell of a lot of ether...spark is great....and have good fuel weather its squirting in the right whole at the right time I don't know
