I have an 89 Turbo II and have a jspec s4 engine w/ the s4 fuel system intact still. I bought 4 brand new s4 resistors 750 secondaries stock primaries... I tried using 10w/10ohm resistors spliced into the injectors to make up for the difference in resistance between s4 and s5 injectors but nothing I try will make the injectors pulse...

Is there something else to look for? I am getting fuel all the way to the injectors as I can smell and see gas if I remove the fuel lines. I also have a walbro fuel pump installed if that matters...

Any help would be greatly appreciated. I need to get this beast running so I can sell it before I leave for Japan!

ok fuel has nothing to do with your problem it can be when u installed the motor you cut off the ground or the other is your PCM/ECU has gone bad and it dose not take much to do eather but because its all 4 u might want to find a ECU that u know is good and try that. PS did u check all your fuse??????

I'm still using the stock s5 TII ECU. I did notice that the previous owner had tapped into the wires on the ECU harness (was probably trying to piggyback).

As far as ground wires go.. which ground would stop fuel injectors from pulsing? I grounded the main engine ground to the bolt on the tranny. I did check and replace a couple fuses including the main fuse....

well check the fuse next to the bat first if all is good check if your geting power to the inj. Well i should tell u that how a MOST inj work is that the ECU gives power at all time to the inj and when it wants it to firer the ECU will give it a ground. With that said if you have power to the inj you need a ground and if the wire is cut or the ecu is failty your sol so check the wire first and with the ECU when ever you handle it you need to be grounded because only 10V shock can **** it up and when u shock a person its around 1000-10000v so make sure if you are handling it gound your self out some way

Oh well, I went ahead and did a compression test for the hell of it and ended up getting like 45psi on the front and 25 on the rear lol... I think my motor's shot.
