SOURCE: Transmission problem

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

SOURCE: Jeep Cherokee won't start, turns off, etc.

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.

SOURCE: 1999 jeep grand cherokee losing oil pressure

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.

Xwhat deactivates asd system on 98 jeep grd. cherokee


my guess this post is , engine cranks ok, but wont start or only runs for 3 seconds. right>? why not post the symptoms first? huh?

many things, will cause the ASD to drop out.
what this relay does, is prevent fuel fires. and is part of secuity system if opted
so there are up to 8 reasons,
i guess you dont have a $9 scan tool>? and didnt scan the PCM cranking.
this page is and all year 93 to now,integrated page.
no need to worry that, only scan it, and see whats really going on.

Does a 1997 jeep grand cherokee lerado with distributor have a crank shaft sensor?


If you are losing power to the coil, the problem is not the CPS. The CPS only times the negative pulses to the coil. The positive is provided thru the ASD relay. The PCM may be shutting off the ASD relay for several reasons. It could just be a bad ground wire from the PCM to the relay box, a bad ground to the PCM, or perhaps the security system acting up. A way to bypass these problems is to cut the ground wire and ground it directly to the firewall.

98 jeep cherokee does not start straight away. No pattern just whenever it feels like it, nothing happens when the key gets turned. but other times it starts with no problem


Sounds like the fuel pump. Sometimes it'll start right up, others it'll crank for 30 seconds. Probably losing pressure. It's located in the fuel tank.

1998 Jeep Cherokee - hard to start


My 98 Cherokee was the exact same. I used to have to turn the key back and forth 3 times and then it would start. Otherwise it would just crank and crank for a while and then start. Pretty embarrassing! Took it to the dealer and they said that my fuel pump was losing pressure. I changed the fuel pump and I don't have to prime the pump anymore.
