Injectors were not cheap but i replaced them along with a new filter, rail, and fuel lines. Got the sled back together (would like to have the engineer that designed the air box castrated) and started it up. Fired and ran for a second and died. Did this a bunch of times but never stayed running for more than a second or two. It sounded better when it started so I think the injectors were part of the problem but I am trying to figure the rest out now. So far I have dumped the gas for fresh gas, put in new plugs, and tested the capacitor. The capacitor tested good and the plugs are getting good spark on pull start. Getting back fires now but I think that may be from a little bit of gas that got into the air box when I pulled the fuel lines to dump the gas tank. The voltage regulator was replaced recently and has maybe 100 miles on it so I don't believe its that. I'm at a loss here. Next step is to light it on fire and walk away from the damn thing.
