Hi. My name is ***** ***** I would appreciate the opportunity to help with your question.

Expert:  Steve replied 11 months ago.

your engine only requires 3 things to start and run:

- spark (as in timed ignition)

- fuel ( as in a correct air/fuel mixture)

- compression.

due to the nature of your problem, I suspect an electrical problem.

measure the battery voltage under the following conditions:

- ignition OFF.

- ignition ON

- with the start button depressed.

- with the engine at fast idle, if it starts.

let me know what you find.
