My truck is cutting out under any acceleration over idle......Ive tried the fuel filter but it still is not working.....It started happening last night after i refueled....It has gradually gotten worse the more i try to drive it....It almost seems like the governor was moved to 1800 rpms....Im wondering if it my be the lift pump, but i can hear it come on before i start the truck...Im also wondering if it is bad fuel...anybody got any suggestions?????

Thanks!!!!

Brandon507, I would suspect bad fuel first, drain some out your fuel filter housing in a clear jar and look at it for signs of water or trash. I assume you changed the fuel filter allready.

 

brandon507 I agree with Mikey first assumption would be bad fuel or water in it, If thats not it. Its probably not your lift pump. The Truck can run just fine with a bad lift pump and you wouldnt even know it. If you can run the codes on it if its a po216 your gonna need a new injection pump.
