    So I recently did a motor swap on my SMR511. New engine went in fine and I got most my plugs plugged up right, although since I have a PCV on there's with auto tune it had a few more plugs than I remembered.

    Anyway went to fire it up and it fired and ran fine then died and now won't run. Seems like air in the injection system or something. How can I purge the air out or? Just need to keep cranking?

    hmmm. how about disconnect the fuel line from the injector and putting it in a small container- then flash the starter button for the 2-second fuel system prime. keep doing that until you get a solid stream maybe? or jump the relay so the fuel pump is on full time until primed.

    are you sure the fuel petcocks to your header tank are on (both of 'em)?

    Good idea, although I just looked and there isn't really any pipes going to the injector. It's all integrated to the efi intake. I did remove the fuel hose from the tank at the efi and there is fuel there, although it doesn't shoot out when the key is cycled or starter pushed. Is there normally a lot of fuel flow there when engine is off?

    Got it figured out. Turns out the petcock on my secondary tank lost its e-clip so it wasn't opening and the main tank had no fuel, or just enough to fool me into thinking it was working. SO, I have ignition!
