Help me H-T, I just got a 90 HF yesterday and was told it had starting issues. But it started and ran fine all day. Now it just rolls and rolls but no start. I also noticed I didn't hear the pump turn on or prime. So I started checking the most common ef issues. I tried pulling a plug to check for fire and there was no spark. So I checked the dizzy and wires, everything was good. So I tested the main relay and it tested good and tried another relay just in case and still no start. I tested the main relay harness to see if it was the problem and that was fine. I ran a jumper to the fuel pump and it worked fine, so its just not getting power. So since Ive just about checked everything else, might it be the ignition switch? Would that stop the jump from running and kill the spark? Help me H-T.

 

Ok I think its the ignition switch. I checked the ignition signal wire on the dizzy and as soon as I hooked the positive lead from my multimeter to it and the negitive lead to the - battery terminal the fuel pump primed and she started. So broken ignition switch?

 

im having the same problem. but if its turning over you ignition switch should be fine.

 

Its got to be the ignition switch. When I ground the ignition wire on the dizzy (which is what rolling the key into the 4th position does) the fuel pump comes on and it finially gets spark. Someone correct me if Im wrong but if it takes me grounding the ignition wire on the dizzy wouldn't that mean its not getting signal from the ignition?
