1994 2wd Xj 4.0L engine 2wd with auto trans 157,xxx miles.
I'm trying to figure out what happened.
Previous owner replaced crank position sensor and ignition coil about 10k miles ago.
Has ran great until I hit a big bump.
I'm thinking there is a short somewhere but have exhausted myself searching for it.
Hopefully someone will know what parts to look at.
Here's what I do know.
-20 amp engine control fuse was blown.
-Fuel pump works, have pressure.
-No spark.
Information that I'm getting from scanner:
- tps above maximum allowable
-charge temp too high
-short in radiator relay circuit
-short in a/c clutch circuit
Where/what is the radiator relay?
Anyone have a clue as to what I may have going on here?
Any help is appreciated.
