Question about 1998 Jeep Cherokee
Will only crank sometimes but when it does it must warm up to running temperature before driving or it will lose power completely. sometimes looses power when driving and doesn't always crank back up.
Your crankshaft position sensor located on the left side of the upper transmission and good luck.

Hi renjay, is your jeep trans an AW-4 or a 46RH? The simple things to check here without getting to the internals are as follows; check your oil level,filter etc. check the throttle linkage adjustment,check the trans shift adjustment also have the TCM tested, the TCM (transmission control module) used with the AW-4 has a self diagnostic program compatible with the DRB II scan tool.The tester will identify faults in the electrical control system it will help determine if the problem is electrical or mechanical, after this it tends to become internal and we can adress that issue if it arises,hope this helps,good luck and let me know how you make out or drop me a line if you have any questions,take care

Did you have the same cranking with no start problem with original engine or did the problem begin when you changed it? I would check codes if you have not already, and would also clean business end of idle air valve (next to tps) DO NOT turn the end plunger while cleaning or it may not seat properly. Do not loose the rubber "o" ring while working either!

keemo68 is right, I had the same prblm and it was one of the relays. There are 4 relays located under the hood, passenger side, just above the wheel. They're quite cheap so buy one, then replace the first one, if still not ok put it back in place and try to replace the second one, til you find the defective one. Think I've paid $5-$6 in a wholesale electronics parts, they're quite standard.

This is not necessarily an issue, but normal physics. I suggest remove your transducer and test with an external, known good, gauge.... Be sure the vehicle is at normal operating temprature....that will give the lowest pressure reading, as compared to cold engine.
