I have checked for voltage and signal on crank position sensor which is located next to the crankshaft. I removed the three wire connector and installed my voltmeter to check for voltage on each wire with key on. I cannot find any voltage on the connector side disconnected.

Hello KARKID19528,

I found some wiring diagrams for you to reference for this problem, there are a few PGM FI relays that could have gone bad, and a wiring junction block at the rear of the engine. You should be getting some kind of voltage. Also check all of the fuses.

Please let us know what you find so it will help others.

Best, Ken
