Well then I think that takes the fuel pump out of the equation.the engine seems like it has to get a running start the fire rock even on the ether a few times on the ether it would pop right off I couldn't let go the key fast enough.which is a sent them and a problem that I read about on a 05. That 05 pick up coil needed to be adjusted and oncethat was done he posted that tge machine fired up better then from the showroom.

Haha sry that was a bad voice to text........ maybe what u r saying about the timed fuel pump would take a bad fuel pump or regulator out of the picture.... when mine starts on ether it kinda sounds it's picking up and building on top of rpm and then will turn into the engine running. Not ur normal turn the key and fires up.... I read a post on a 05 500 having pretty much the same issue as I but he was able to adjust the pick up coil and once that was done his machine then started better then it ever did. I'm not sure on my 07 800 that their is an adjustment. Twice on ether my machine shot to life with just a slight turn of the key..

I would still want to check fuel pressure readings...at idle, while cranking, at part throttle running, and see if it holds pressure while off, etc.

Pressure should be higher after only one key on cycle.

Are plugs dry after cranking?(w/no start fluid)
