Hoping you guys can help me out. I have a Nissan with a K25 engine and a E35 (F/inj disconnect) code. I searched the code here and went through what info I have and haven't found the cause. I checked the injector connector and fuse. fuse is good and I have.9 ohm across the injector. Spec I found was 1 ohm. I checked all the relays and connections to the relay panel. I still need to check the harness back to the ECM ( didn't have the pinout for the ECM connector at the time). I tried to clear the code and couldn't with the pedal procedure. Either I did it wrong or it is a hard code. I assume the latter. if the harness tests ok, is there anything else I can try without having laptop access? Could it still be a bad injector? I do have fuel pressure on start up. With the key on, I can disconnect the fuel line and I gives a good blast of fuel, then shuts off in a couple of seconds. I couldn't pressure test it though. I found a 4 psi spec for LPG running. Does that sound like the correct spec? It may have been more than that before start up. Unit starts and runs just fine for a bit, then stalls, but it can be restarted.

I read your problem l would replace the main fuel injecter as for the fuel pressure it is about 4 to 5 psi when running could be a bit higher with key on not running main injected is closed until moter is cranking than it is pulsed from ECm.
Hey was this problem ever figured out? I am having the exact same problem. On a cat P3500 which I believe are the same.
I tested those wires for continuity and shorts to ground, all good. I didn't check voltage at the injector though. I didn't have a spec and figured it would be variable. Do you know what it should be at the injector, key on not running?
LPG fuel injector circuit open. You need to test wires from computer to injector
I confirmed that there is no resistance in the wires between the lpg injector or lpg assist injector and the ecm plug. Managed to clear the code by disconnecting the battery but it returned as soon as I started the machine. Any ideas, please?
