Thank you for using our site, My name is XXXXX XXX I will be helping you with your problem.
If you have a tachometer, Disconnect the wire on the "S" terminal on the tach and check for spark again.
Make sure that you have your safety lanyard properly installed.
On the back of the key switch you will find a black and a black wire with a white or yellow tracer. Turn the key to run, and with the wires still connected to the key switch, check for continuity between these two wires. If you have continuity when the key is in the run position, replace the key switch.
There is no safety lanyard installed. from the shifter box there is a harness with a purple , black, gray, brown with white stripe, tan, pink with blue stripe wires and none of them are hooked up to anything I believe these are suppose to go to the dash and operate the tach etc, are some of these wires suppose to go to a safety lanyard?
Ok tried that and there is no continuity between the two wires.
