Ok long storry short? Bought my 01 from a shady used car lot with a bad cylinder head,. The Problem was masked with a few over the counter remidies .The jeep ran graet for about three months until it stated overheating . Looking deeper I noticed that the car lot had removeed the thermoastatit and the radiator and motor was loaded with Stop leak . I got screwed but I am tryying to make some lemonade ot of some bad lemons.
Bought an 04 motor with 36k from a local Jeep dismantler. When I had the motor out to compare, we realized that the Grand Cheorokee block is totally different and would not except the accesoors from my 01 XJ . So we exchanged the 04 motor for a correct used 01 motor.
After spending all weekend installing the motor ,it will not start. The old motor started fine and ran . After about 5-10 miniutes it would sattrt puking water into the cylinder head . The new engine turns over about 5-6 times and than sputters without starting. If this were not computer controlled I would be looking at the timing . That said I think it may be the Crank Positioning Sensor . I should have removed it from the bell housing before the engine swap. Could bumping it during the install or removal have killed it?? I pulled it out to inspect and it does look to have made contact with the Flywheel ring.
I have one ordered from Autozone ,but if this does not cure the problem ,I am at a loss. Any Ideas???
BTW While the Jeep was motorless we went ahead and installed a 4.5" lift that I scorred from Pick-N-Pull ,Half price . It is not the most expensive kit out there but for $200 bucks I got everything including Shocks .

. It sounds to me like your culprit is your crankshaft position sensor or CPS. It doesn't take much abuse to damage those little guys and if you left it on while removing the engine and bumped it with anything heavy, it could have damaged it to the point of not working. I was reseating a CPS on my 1990 one time and knocked the magneto off of it, it would still start but shot a 4" long blue flame out the tailpipe. The later CPSs though will cause a no start if you disrupted it I'm almost positive. Replace that and let us know what happens. And on the 4.5" lift, sounds like you got a smoking deal, nice score.
