with the ecmb fuse blown, I dont have fuel or spark. I replaced 20 amp fuse with a 25 and truck started and ran for awhile. I shut it off and waited alittle while and restarted, blow the fuse. I put in a 30 amp fuse and it blew while cranking. Also i dont here the feul pump prime the system when you first turn the key on. Thanks Jerry

Hi fordtractormanjerry, Welcome to 2carpros and TY for the donation

You have a short on the fuel pump circuit -Disconnect the fuel pump connector and tell me what happened to the fuse, we start here

I raised bed up and unhocked feul pump, it tryed to run off of feul in system. I sprayed carb cleaner in air intake tube and it would run. Im going to replace the feul pump. It has to be the problem, Ive never seen a pump act this way, usually they work or dont work. Thanks Jerry I put new feul pump in and it runs!!!
