Expert:  Jason replied 20 days ago.

When did this problem start? When did the engine last run correctly? How old is the fuel? Have you checked compression, spark output, and fuel pressure?

Customer: replied 20 days ago.
started about 1 week ago. haven't run it for almost 2 weeks before and it was just less than 1/2 tank with fuel additive. plugs r 4 years old (150 hrs) and look clean. don't know compression or fuel pressure

It doesn't sound like your are going to have the tools or ability to diagnose and fix the problem even with my help. Is there some way I could help you? Did you have any general or specific questions for me?

Customer: replied 20 days ago.
