Well I've searched and I wanted to be sure how I could be sure that my ignitor is working because I am not getting spark and I checked continuity from the plugs and the ignitor and they all have continuity. Than I checked that polarity test according to the FSM and that checked out, there was continuity. Now my question is, is there something else to check if the ignitor is working of if the wires are sending a signal? Lets just say I'm not mr electrical. Would I be able to check if voltage is coming from the wire or on the ECU?? Thanks BTW, its a Q45 ignitor on the SR, I wired it up according to Heavy Throttles guide.

Nope, my resistance is like 25ish OHM's on 2 ignitors that I have. Does that seem normal? Where can I check for voltage on the connections coming out also, shouldn't there be a 12v coming out?? Apparently there was no FSM ever made in PDF for the Q45 under 94.

im sorry man i dont have too much experience in testing the ingnitor. but i know tenkawa_akito knows alot about the sr hopefully you can get some input from him if he checks out your thread. i was just wondering whats going on with your ignitor.

are you sure its the ignitor? it could be a wiring problem. check the wire near the battery. make sure you hook up the black/red(main ignition), blue/red, brown (o2 sensor) to the the black/red wire on the ka harness.

Well my nieghbor checked it out and found out that the plug actually gets voltage from one side of the CAS plug but not the other, the other being the one that goes to the CAS itself. So I'll replace it and see what happens. thanks for the help though guys
