#4562 of 5143 1997 Jeep Grand Cherokee Stall Problem
Oct 02, 2009 (11:46 am)
I can't believe how many people have written in about the stalling problem with their Jeeps. Wish I had thought to find this site about a year ago - before we replaced several parts - due to the mechanic "not seeing the problem" while it was happening. I told my husband what I had found out about people replacing the crank shaft sensor - and he called the place who had done all the work last year that didn't fix the problem. One guy tells him "oh, that's a common problem with Jeeps." Well, we put the Jeep in the shop (an almost one hour ordeal to get the Jeep TO the shop that was less than 15 minutes away - because it KEPT STALLING and I missed Grey's Anatomy, too - and the mechanic calls him this afternoon to tell him that the computer is saying the CRANKSHAFT itself needs to be replaced and that in the 8 years he has worked at this location, he's not heard of replacing the crank shaft sensor ever!!!!????? Personally, I think it's bull - we're getting the same old thing - "it's running just fine"...but I'd much rather try to replace a quoted $75 part (includes labor) than a probably $500 part. Sure hope this works!!

what weight-(5w20?-1w30/40? )..whenever i start hearing scary noises-especially in the lower crankshaft area,i think the oil is too light..
-once had a ford aerostar,with a 3.0,started "knocking",while using "multi-weight"oil(10-w-30),..started using "racing oil,a -sae 50-,no longer heard the noise,and that engine lasted me another two years/with a total 160.000 miles. sold it to someone who needed it that bad,and i DID tell them about the noise,and what i did,so maybe it'd last them for a while..
--today's oils,are thinner there wasn't even a 5w-oil available back in the -70's..don't use that-nearly diesel oil in your crankcase !..the auto makers -in their effort to sell you to sell you a new car,recomend you use that garbage,so you'll need a new engine-and probably just go ahead and get a new car-well,before the economy went "around the bowl,and down the hole",it kinda worked..
--sorry about going off on a tangent,but- try the heavier oil-change the filter,see if the oil pressure gauge drops when you hear the noise,also,maybe check and make shure your not just low on oil??..
--put some "friction proffing" stuff in it(slick 50-z-max-etc..)
--take care of your engine-and it will take care of you-maybe..
--good luck !

-sounds electrical..check and make shure battery terminals are clean..after that,i'd look for a loose engine ground wire-maybe even on the power control module-the main computer for the car..,but probably something vibrated loose.. try taking it to a auto parts place-and see if any "trouble codes" show up with their tester..
--my-98 gcl just started showing a empty tank-when i knew i had at least 1/4-even th "low fuel" lite came on..
was still running,so drove home-while smelling for "burning wires"(none-thank god !)..mext day,my 1/4 tank was back-and no lo fuel lite..put some in anyway-just to see if needle moved-it did..
guess this is one of those "bugs" that make owning a complicated piece of--..--gear sutch fun..especially now-when all that stuff is getting old..
-----don't ever want to find out-but wonder if the airbags would deploy?after twenty years??..makes you think..makes me drive better -where i shouldn't need them..nice and easy..

i would try the crank sencor as the magnets that control the crank sencor are perminat and the only whay that they can getoff is to have the crank brake or bolts to fly wheel come loose (if thwat happened you would hear a hole bunch of noise ubder your jeep)

The crankshaft position sensor is a fail item. It's a challenge to get at, but can be done as long as you have an extended tool set. When that gadget isn't working right, the engine barely runs.
#4568 of 5143 over 2 rpms when it starts
Oct 05, 2009 (12:00 pm)
I have a 2000 Jeep Grand Cherokee limited edition that has about 173000 miles on it when I start it it revs up to or over 2 rpms and then it takes almost a minute for it to rev back down. Also it has a ticking in the engine at all times I was told once that it could be a collasped lifter? Can you help me figure out what I need to do to fix this

#4570 of 5143 93 Jeep Grand Cherokee Laredo mechanical issue
Oct 05, 2009 (3:01 pm)
My son drives a 93 Jeep Grand Cherokee Laredo. When he is driving under 50 mph and hits a pothole or blemish in the road, his right front wheel will violently shake, the vehicle jerks to the right and looks like the wheel is about to fall off. If he reduces speed, the wheel will correct itself. We've replaced the gear box and stabilizing kit. The ball joints are slightly loose but our mechanic says not enough to cause the wheel malfunction. Mechanic is out of ideas. Please help.
#4571 of 5143 1994 Grand Cherokee no spark-no fuel
Oct 10, 2009 (4:45 pm)
I have a 1994 Grand Cherkoee,4.0 straight 6 Auto 4WD.
I have no spark, No fuel.
when i turn key over ,the check engine light doesnt even come on as normal when you usually turn key over and "dummy" lights test i guess ...where all console lights come on for a second.
Ive changed crank sensor,cam sensor,relays related to this stuff ...The reason i changed relays was ..i would hear a clicking noise in the box containing all the relays it starts as a slow clicking noise then the check engine light would eventually come on and the clicking would stop ..
If the Check engine light comes on ... the truck would start. and the code for crank sensor would come on .. i changed the crank sensor and still nothing ...
At 1st the truck wouldnt start at temperatures below 50 degrees but now wont start at all ...
PLEASE HELP ..I DO NOT KNOW WHAT TO WORK ON OR CHECK NEXT!
