Hi everybody,
I replaced my solenoid (thanksTyler C), now then engine turns over without jumping. I pulled the plug and noticed that the only time I got spark was when I turned the key off. I don't have the V/R hooked up. Could that have something to do with the problem?
I'm encouraged that I at least I have spark. But I need advice as to what might be wrong. Thanks in advance
