Top 20 1985 Jeep Cherokee Questions & Answers

for a vehicle to feel different and empty , it begs the question --did you get into the right vehicle would not be the first time that the key fits the switch of the same make of vehicle but belongs to some one else next have the service center check for loose starter and other bits falling off run the fault codes

Relay does not sound right to me. Use a voltmeter or test light to probe the fuse box. Is there power at the headlight fuse? Problem may be in the power box itself. I don't believe there is any relay that runs all the lights.

auto or stick trans, we find out its an AUTOmatic.this trans is most likely a pure hydramatic.and no TCM tranny brains then.check levels next. (by the book dont guess)check the shift cable, for proper movement. in all gears."selections, they are no gears" the automatic shifts via clutch packs not gears. like stick does.move the shift lever and be sure the transmission end of the cable moves 1 for 1 same; that is moves to all transmission shift positions. (at trans itself)if not the cable is bad or came loose.inspections are first never transmission swaps, blind (on a whim);the FSM book covers all this."chapter, on car service" all cars made have this chapter.. an amazing fact.next, is get a new filter in the trans.if clogged, the pump can not suck AFT. (shunted input)so line pressure drops, and it cant shift.no need to do the stall tests as it fails 100%next is line pressure, tests. if that fails,it needs a rebuilt trans.but dont take my word , read the book.or ask your tech to do the tests, he knows, how...

no need to adjust the timing you need to turn the rotor to the left a it will start and it's not a v6 jeep only make inline6

could well be 180 deg out and check dissy rotation that tyou have set plug leeds in right order and going the right way and starting at the right place no 1 tdc firing not exhaust

several things to check for this one....since its happening under a load.- timing- ignition (spark plugs, distributor, cap/rotor)- Idle controller- exhaust system

sounds a little bit like a timing issue

Sounds like a vacuum leak.

Could be a bad ignition module or could point to faulty wiring. The longer your vehicle runs the hotter some electrical components get and that's the 5 - 15 minutes it wants to cool down.

No torque specs about this CKP sensor...

1. The CKP sensor is located on the transmission bellhousing. Disengage the sensor wiring connector and remove the sensor wiring hold-down clip from the fuel rail.
   
2. Remove the sensor mounting bolt and carefully pull the sensor out of the bellhousing.
   
3. Installation is the reverse of removal.

Hope helps.

Check for spark at any of the sparkplugs.If there is no spark at the plug then replace the distributor ignition pickup coil.

check all the water lines, coolant hoses and make sure radiator is not runing out of water, after check this, check oil level, otherwise or last thing might be temperature sensor. hope this helps good luck!

Check your comrpession. If you have 1 or more cylinders with bad compression, you could have bad valve(s) or if the suspect cylinders are adjacent, a bad head gasket.

so you tryed to check the timing how about the destibiter cap an the ponts !

You need a slim jim to open the gate can you open it from the inside they have plastic linkage and they tend to seperate and break off

Is it a an 85 or a95? I know of two switches on these vehicles, one is a four port vacuum switch on the top of the transfer case, you must unplug the vacuum line, and unscrew it from the transfer case. The other is on the front axle. The one on the transfer case is rather difficult to reach, it is hex shaped for a wrench. Unsure of size, it is large though. The one on the front axle is part of the axle shift motor, is unplugged and removed for replacement. I believe the one on the axle only serves to turn on the 4x4 indicator light.

It's probably a collapsed lifter. Oil sometimes helps but after time they wear out. And don't pump up to max specs especially when running.

1985 Jeep Cherokee came with either a 4 cylinder 2.5L with a 1 barrel carb or a 6 cylinder 2.8L with a 2 barrel carb. The 4WD only had the option of a 4 cylinder 2.1L turbo Diesel.

Could be faulty Thermostat/ Leaky head gasket or bad water pump.. Check the oil pan for any antifreeze,if its OK the do a compression test on the cylinders to check the head gasket, and replace the Thermostat if its defective. and check for any antifreeze leaks on the ground. Good luck bro
