My 96 has just 110,000 miles on it and for some strange reason it blew the#22 fuse (the main computer fuse) and of coarse the truck came to a sudden stop. Replaced it and then again while pulling my 5th wheel home after about 250 miles and slowing down for construction, it happened again???? What in the world would causes this 30 amp fuse to start to blowing????? Any solid ideas? I'm really concerned that this might happen in the middle of the freeway some day
Fuel filter heater in the filter canister is shorting out, common problem.
Unplug it, it's center connector on drivers side of canister until you can get a replacement.
Or just leave it unplugged like many do.
You know I really love this forum sight. I haven't participated very much over the years, but you guys have saved my butt more than once. Keep up the great work, and thanks once again. Dennis
Or, you can do as the PO of my truck did and leave the fuel heater hooked up and bypass the fuse: thereby melting wires together and blowing all the other fuses down the line...
I'd suggest disconnecting the heater. I live in upstate NY, and mine starts and runs fine without the heater.
If you don't like the unplugged wire dangling, you can unplug the heater element on the inside of the fuel canister the next time you swap your filter.
The bottom longer wire is no longer on there as well. Was unecessary, so I removed it also. So only the water sensor is hooked up and the IPR.
I just used a screw driver to pop the connectors out so they are replaceable, not sure what I was doing, but knew they were not used.
Most guys have no fuel bowl, they just cut the wires and leave the IPR wires on there. I took mine out and put RTV in the hole to keep the connector clean inside.
Sucked too, cause the connector that is on there to the far left was bare wire for like 3-4 inches, so I fixed it with shrink wrap and RTV and figured out I did not need it.
Yes, i shrink wraped all the IPR wires together. I removed them from the connector noting their places, used the shink wrap to bundle them up neatly and then re-assembled everything.
And yes, that is an IPR Connector repair you see there as well. The cleaner I used when I got the truck ate up the rubber inside of the connector. I used electrical tape before. This time I pushed heat shrink down in there and then filled it with grey RTV and then I heat shrinked the wires as you can see.
