I have a ram van 5.2 1997 that keeps blowing the fuse. You will be driving down the road and pop you are dead. gone through many fuses but then will run for a few days with no problem. Is it possible bad ecm? Need a starting point. Thx.

 

Pretty difficult without a inductive amp probe. Could be any injector/solenoid/relay or fuel pump. I guess you could ohm out each item and hope you catch one out of spec...Suggest a shop on this unless you have deep pockets to toss money at the problem.
