DEcosse's advice - To help isolate the problem, turn your headlights to high beam, hit the starter button while monitoring the blue high beam indicator. If the light goes out and the starter does not engage then your problem is probably in the starter solenoid (or solenoid wiring). If the light stays on, then the problem probably lies within the starter circuit (starter button to the starter relay). I have problems with no start or starter engaging then dropping out after a couple of engine revolutions. The high beam light goes out and stays out while button pressed so I think my problem lies in the starter solenoid spring. For sh!ts and giggles I cleaned all contacts, connections, replaced starter relay and yet my problem persists. Someone on this site shortened his solenoid spring by 1/2 inch and it cured his no start problem. I may shorten my spring (after I measure the solenoid plunger travel). I'm just too lazy to pull the starter again as it always starts after a couple of attempts.
