Pretty sure the ECM B fuse ties in with the fuel pump. A bad fuel pump blowing the ECM B fuse is a common failure in the truck circles as well as it being pretty common to kill an in tank fuel pump with a bump in the road. IMO adding all that togeather means the fuel pump died after hitting the bump and its killing the ECM B fuse.

My .02 FWIW.

My guess was a short, which is what the fuel pump is doing, beat bottom of tank with a rubber mallet see if it runs, worked for numerous people,

actualy i found the problem. it was a short on the oil pressure sender. the wire was worn through and was tuching the sensor and blowing the fuse.

Havent had that one come through the shop yet so I'll be filing that away for future reference. Learn something every day :idea: .
