i have had grate luck and very happy with my raptor pump, but this morning it would not make a sound and its a no go for the old cummins it poped and farted and that was it. i havent checked to see if its electrical or not yet, had to get to work just know i got trouble. i drove it about 30 some odd miles yesterday and last night with no issues.
thanks in advance i got to have my truck

 

My guess would be a fuse, or a ground or a relay box
