    OK,

    Checked the wiring, replaced the fuel pump relay and the fuel pump and still the fuse pops when inserting it. What the hell?

    Any ideas?

    I'm just taking a stab at it, but the only mechanical thing I can think of is a clogged fuel filter. I know the ECM B topic has been covered on here before, so please school us on the subject.

    I had that problem awhile back, found out the pick-up coil inside the distributor was fired, burnt out, whatever, replaced it and have been fine since, don't know what caused it, :dunno: but it works now.

    I didn't think the pickup coil had anything to do with the ECM-B fuse.

    I didn't either, but i went out one day to start the truck,,,and no go, checked for fuel, had it, spark, had it, somehow it started running for a few seconds, then died,,,then i had no spark, checked everything out and found that fuse was blown.

    Replaced it and it blew out again.

    Replaced alot of electrical doohickies before i got to the pick up coil, saw it was kinda melted or somewhat. Replaced it, it ran for a day, then burnt out again,,,"El Cheapo" at Autozone.

    Bought a better unit, and have been running it ever since, been about 2 years now..


    I dunno,,,this is just what happened :dunno:
