I've been checking things all day. Main EGI relay is working, have fuel and fire, tried the CAS trick to see if the injector are clicking and I don't hear them. I hear the coils but no the injectors. I also have power to the injectors on both side of the plug. Not sure why the aren't firing. Will start with ether until it runs out.

S5 harness. Its in a samurai so yeah... I have the main computer hooked up but there was a small computer in the pass side kick panel that didn't think was needed does anyone know that that one is and if its needed? I hope not because I don't have it.

 

so if the injectors have power, that means the ECU needs to trigger them. last time i saw this the CAS wasn't working. no RPM signal no injector...

i guess its possible that the ecu grounds are not good enough, but i kind of doubt that.

hmm i think if the ecu is powered and it sees RPM it should be enough to flood the engine, lol.

 

I doubt the cas seeing that I the one on the car nor the other I tried made the injectors click. I thought about the ecu grounds too and checked and found a ground wire loose, but didn't fix it.

 

I'm assuming since it's in a samurai this would be the first time you're starting the engine in it? Are you using stock injectors? Are they high or low imp? Are you using the correct ecu? Is it turbo or n/a?

 

everything came from a stock s5 car haven't changed anything.

 

Each injector has two wires, one power one ground. You're getting power so cross that out. The other wire is the ground wire which goes directly to the ECU. Check the injector pins at the ECU for ground, pins 3F, 3C , 3H, 3E. You can also check for resistance from one of the injector harnesses to connector EM-03, it plugs into the back of the ECU. You can also try a noid light. Or easiest way, swap in another ECU and see what happens.

 

its not going to ground like it should, so what do you think the problem is?

 

What do you mean its not going to ground like it should? Are you talking about the ground wire from the injector harness to ECU

 

i assume if you give the injectors power and ground they do click, ive seen stuck injectors but to have more than 1 would be really weird.

the only other thing off the top is that maybe the engine coolant temp sensor is bad, if the ECU thinks its really hot, you will get almost no fuel

 

nevermind! I'm a retard! when I put the harnesses in the truck I didn't connect the two together. Put it together and it started right up! GREAT SUCESS!!!

 

Congrats. What exactly didn't you connect together? lol

 

lmao! good, cause otherwise we had no idea what was wrong

 

no idea how the coils were firing then.
