I looked at 4.2l engine early production wiring. My wiring doesn't say pcm fuse, it just gives a number and amp rating. If it is the fuse I'm thinking about, like hunting a needle in a haystack. That fuse supplies many different circuits.

Just a thought, try pulling the fuel pump relay and see if still blows the fuse. That may not be conclusive?

I just rechecked the wiring, I don't believe pulling the relay will help.
