Here is a checklist you need a volt ohm meter.
#1 does the starter work from the ignition switch.
#2 check the dizzy black is ground orange and purple are the reluctor check them for continuity and that neither is shorted to ground.
#3 check for power to the coil and red on module with the key on and in the start position. (disconnect the little wire to the starter solenoid so it dont crank)
#4 check for power to the white wire on the module in the start position
#5 make sure everything is connected start wire at solenoid, green from module to neg on the coil and dizzy to module.
#6 check for spark at the coil put a spark plug in the coil wire to the center of the dizzy and set it on a good ground,crank on it if you get a steady spark then your ready to time it.
#7 if not check the coil for spark turn the key on and with the plug in the coil wire take a jumper wire and quickly jump the neg terminal on the coil to ground you should get spark if not the coil is bad. If you get spark at the coil with the jumper your module is probably bad. Gl let us know either way
