Hey guys. Last week I was driving my 92 4 cylinder 5 speed and it stalled at highway speed. I noticied that the EFI fuse was blown. I replaced it and the truck started and drove about 500 ft and blew again. I had problems with rough idle at start-up in cold weather. So I took a stab at the throttle position sensor. Now with the sensor plug in or not I blow fuses when the iginition is turned on. Any ideas would be helpful.

 

sensor aint got nothin to do with EFI fuse.that'll be tough to find.i'll get back to you.

 

Two things to check...

First, I have a 3.0, so I'm not sure where your O2 sensor is, but find it & trace the wires & make sure they didn't fall on the hot exhaust & get chewed up. If so, get some butt-splices & heat shrink & resplice all the wires (3 on mine, one of which was coaxial). If that's not it, it's probably a bad fuel pump. Not sure where yours is, mine's in the fuel tank... I just fixed that problem, & it was the O2 wires.
