So 2 weekends ago I installed a raptor 100 lp and now my truck won't start first crank. It will normally take 2-3 tries and my foot on the throttle about 1/8 into it. I have checked for fuel/air leaks and came up short. I replaced my rubber fuel lines and that didn't help. As well as a new ofv50 from torktek. Once the truck runs I can shut it off and turn it right back on. I have researched a lot about it and now I'm just lost. I'm starting to think my fuel shutoff solenoid might have gone out but I'm not sure.

Anyone with helpfully information please chime in. I'm still a little new to diesels. All the work in my sig I have done myself other then the timing.

Thanks
Garrett

 

i have ran into the same issues before installing fass systems. my issue was i was using liquid thread sealant on the fittings instead of thread tape. and the suction side wasnt sealing properly, causing air to get in around the threads and the fuel was draining back to the tank. my fix was i used thread tape and then the liquid thread sealant. hope this is any help to you.
