I have an 89 Cherokee Laredo inline 6 and i was driving down the road and my stereo turns off, then, my truck dies, ive had this problem before because of a p.o.s. battery, and i will mess with post and cable connections and it will start back up, but this time it doesn't, i take a battery out of v-8 air conditioned plymouth fury and put that in and still nothing ,i have tried all the obvious, jump start, nuetral start,checked my ground and power wire, but my lights will come on, but my power windows will not move, also i have an alarm with a mind of its own, i don't have the clicker for it so i usually just unplug the harness from the module then turn my ignition forward then proceed to re-engage the alarm and it will start up, but when i put the new battery in the alarm decided it wasn't going to go off anymore, so im thinking its the alarm because it does have an starter kill on it, but my question is, is it the alarm? the battery just doesn't have enough amp power, or something else???

I know that in a 1995 jeep cherokee there is a fuel filer in the area above the rear axle. It is the tube or canister type with an inlet and outlet. This might not apply to a 1989 though.

Sounds like possibly a more serious problem, lack of fuel delivery almost always shows itself at higher engine rpm when fuel demand is high. Best case scenario your electric choke is not working but those symptoms are typical of low cylinder compression, probably a high milage motor around 200k? If you have not already check your plugs and run a compression test,below 125 psi becomes a starting problem. Let me know at dft@deantalkington.com best of luck

i had a similiar problem with my jeep. i tried everything thinkable, until i discovered it was the coolant temperature sending unit. it's about a $20 part and is easy to change.

This is to Richard. Try checking the crankshaft position sensor. It is located on the bell-housing top left. I had the same problem and 4 sensors later, I am finding out it might be the computer that is causing the problem. Not enough amperage to the sensor which requires 5 volts and it is putting out 3.

Richard, I have the same problem with my '88 Laredo. Solution was the Intake & Exhaust gaskets had to be changed out. My Jeep would crank over forever, starter fluid was a good help. On Hot days it was worse. Cold days it seemed to be ok... now that both gaskets were changed out ($29.99 Canadian for Felpro). it starts with no problem... Hell of a long job to switch them out though.

I've been having similar problems with my 88, but in my case spark was there and no fuel. Turned out the wire going to the fuel relay was broken off way down in the wiring harness. If you guys ever see less than the required voltage (like 3 when you should see 5 or 12), this could easily explain your problem. Try wiggling all the wire harnesses and see if that changes the voltage. If it does, safe bet a wires come loose.

I am having the same problem with my 88' jeep Cherokee. Bad when it's cold, better in warm weather. Takes forever to start but runs like a champ once you get it started.

Well get that guy that said to get a chevy out of here ive pulled out many STUCK chevy trucks that cant handle offroading. Anyways you can try to replace the Crankshaft Position Sensor and the Fuel filters Ive got a 90 cherokee and i had to replace that. You might also want to try to get new dist. cap and wires. And maybe a new ignition coil. On that year cherokee the most prevalent problem with hard starting is the cps.

check to make sure that you gas line isn't frozen because it would make it hard to get gas to run it. or maybe you have a sensor that is going and doesn't like the cold

I own a 89 jeep cherokee with a 4.0L in-line 6. I've been through allot with it. If it only runs well at high RPM and then is slugish at low RPM's runs at full throttle then check the fuel pump pressure and regulator. Chances are it's sucking fuel in when it's wide open - yes believe it or not! If it's not getting spark at all or runs and then cuts out for no apparent reason when warm without spark and then starts when it's cold again- crank shaft sensor.

Try checking you battery cold cracking amps. The jeep battery is a 750cca I believe. I had the same problem in my 99 grand Cherokee and that was the cure.

QUESTION: My 1989 Jeep Cherokee with a straight 6 runs fine. But its very hard to start. It cranks and cranks and cranks until it starts. Sometimes the battery wears out before it starts. I put in new plugs, filter, coolant sensor, and o-rings on the injectors. Yet, the problem persists. Any ideas???

Same problem with a 01 Cherokee. It's the fuel regulator. It doesn't pump enough gas to start the engine. Key the ignition twice before cranking, it then starts right up. Chrysler makes an after market kit to fix this, but you need to drop the tank to install.

I have a jeep cherokee laredo 1989, changed the computer, new cat. . It has progressively gotten harder and harder to start, and now after a long drive to cali. it decided it doesn't want to start at all. When I turn the key to start it, all goes well ignition works fine, but when the engine starts, the rpm's go up to about 1500 then drop off immediately and the jeep stalls. It does not start, I thought it was the computer, but I was wrong. Any Ideas? I smell fumes from the engine, and a lot of moisture comming from the tail pipe..........

I just recently had hard start problems, which became a no-start problem last week. Went to check the crankshaft position sensor, and found that someone had routed it over the engine to body ground strap, where it had rubbed through, and was grounding out. Taped it up, re-routed it to prevent this from happening again, and it fired right up.

Try checking the ignition control module, I had an 89 and stalled it in a river, after everything dried it still wouldn't start so I replaced the ignition coil, and wham, it ran great and the rpm'sdidn't even stall during idle...which usually killed the engine.
