So last night i replaced the TPS. The good news is that the engine now starts right up all the time now. It even fires faster then my DD xj. the bad news is that there is now an engine knock under load. When the truck is put in drive/reverse, the engine has a nasty knock every 4 or 5 seconds...

I'm gonna check the ecu now. The TPS is definitely the 91+, and its an automatic transmission.

Oh well thats good to know, at least I unhooked it. I just picked up the part and I'm about to go change it, wish me luck. Thanks for the other advice about the testing method, I just haven't got around to buying a voltmeter yet.

As far as i know, the engine was running great after the swap, however I don't know how much to trust from the A****LE that sold me the rig. Thanks for the tip about the ground at the back of the valve cover, hopefully its that simple (though I doubt it!) When you say the bellhousing, do...

So I had what (hopefully not) appears to be a lack in judgement buying an 89 xj. The truck is badass- its got a lift, sway bar and 33 inch tires so you can understand what compelled me. It has a new motor however, apparently out of an 94. The truck had obviously been driven hard, I managed to...
