check the emergency shut down valve on top of the Injector Pump... it is run by the T handle top dead center on your dash.. You have to manually reset it under the hood, or thru the fender opening because they usually do not push in well and just kink the wire...ask me how I know, right John Tennis????

Multi or Cummins?

thanks for the replys---took fittings apart and put tape on all threads and made sure all tubes are pushed into the fittings before tightening any nut---hopefull that wii work ---easier to find the problem with a in tank pump

sure sounds like a leak in the fuel line,, check the valve that is under the floor under the drivers side seat. there is 6 lines there that might give you a leak. i looked for over a month to find my leak and i had to pressure up the system in order to find it

I would recommend by-passing the plunger that sits just before the fuel metering pump. The plunger is used to boost fuel pressure in the line (much like pumping the "bulb" on the fuel line to a boat motor). That plunger, although great when it's working, more often than not sucks air and causes problems.

I just replaced all the lines under the cab in my 818 on the spider valve or the tank selector valve and what a difference. now this thing moves like it should
