Started to winterize my 2007 300xs. Pulled off the fuel line and connected a separate tank with mix. Tried to start motor and all she did was crank not fire. Is the coincidental?

Kill switch? Probably not but I cant tell you how many times we've seen it.

That is what I was thinking. It’s like leaving the drain plug out, either you have done it you’re gonna do it or you’re lying

I am also thinking kill switch. I bet that's the beotch I'm looking for because this motor has done me no wrong.

New kill switch/neutral safety OK. No spark on #2 and #3 coils. I've heard coils go bad but all 6?

Fuel prime sequence. Squeeze primer bulb, hit key for 10 secs. Repeat several times to prime the whole system. It's in the installation manual...
