My 4.2 has just had a nice MC2100 carb upgrade and worked great, for about a week
Then started cutting out, stalled/died altogether, replaced coil... worked for 500 yards... towed home
Now I gather it's likely to be the Ignition Control Module. I can't find this. Can someone post any pics... is it supposed to look like this?
The manual states it's on the passenger side firewall.... nope!
Some other guys here have said it's against the drivers side, beneath the battery on the firewall....
I can't find anything that looks like the above. I suppose it's conceivable that 20 years of PO's someone may have swapped something (else!) around
