It could be an air leak in the system. I had a hard start problem after i did some work on my system, it ended up being a loose fitting and it was loosing its prime sitting over night. so double check all the connections to see it you got a small leak.

thats what it acks like ill re check. is there a check valve in the stock lift pump? and can i run the fass through the stock LP?

Had the same problem after installing banjo fittings one time...took and gave a little more torque on each fitting and the problem went away...sounds like air...

Ok i checked and rechecked all fitting are tight. the thing that has me stumped is that half the time it starts perfect this evening i went out and started it 4 x and all 4 x it fired the 5th time i had to crank on it for 10 sec. seem to be no pattern it started fine almost all day but then it takes for ever?

Maybe the lift pump pressure needs adjusting. The FASS guys know for sure.
