I HAD THE EXACT SAME PROBLEM, AFTER REPLACING EVERYTHING I COULD THINK OF I ENDED UP BEING THE CRANKSHAFT SENSOR. IT COST ME $60 AT MY LOCAL AUTOPARTS STORE! BJAM95

Hello blohrd3, I am not sure of the name of part(if honey could be reached by phone I would know). But is right behind your overflow canister on passenger side.Is a black flat rectangler shape box. Is pricey if you get at auto parts store or a Jeep dealership, but go to the junk yard with yours in hand(this takes a few hours to unassemble and reassemble) to make sure that your part number matches the junk yard part. I called Jeep to get my part number and it was entered wrong from manufacture, but junk yard was telling me my number that came with my Jeep and they were right. Jeep dealership was amazed, but they weren't happy because they said noone had this part not even the junk yards. I checked for my self only to be told by a knowledge junk yard employee that the Jeep dealership is giving me wrong part #. So I went to dealership and checked out their info. and it said the part # they were saying it called for, but I was a smart paying customer (regularly with my Jeep) and asked if I could look at the part. Dah, there own mechanic and the day management didn't check to see if the part# on their computer to the part from my Jeep matched. If they would have they would have looked like a brillant crew to me. NOPE, they just wanted me to pay over $600.00 and wait 2 days for the part. So I taught them a thing or two. Also I had them install this part I picked up for $97.00 at junk yard(which they said after I showed them the mess-up they are not liable for any damage this part can do if not the right one.) Well as you might guess after years of going to this dealership and lots of $$$ spent. I have not returned because of the idiot response of installing a much cheaper part and the part numbers matching, they will not be liable for any damage because part number does not match what the manufacturer said is the part #. STUPID, STUPID! So good luck and find a few jeep owners when you are out and about and see who they recommend to take your jeep to. My mechanic is a off the beaten path and he will match anyone in town price to fix my jeep. I have saved over $1500.00 already. And jeep is tight, stiff and runs like a dream. "It's a Jeep thing, you wouldn't understand." I have this saying on my back window below the wiper blade (its path of movement) Need any help or need a Jeep shipped to you? U can find me gnctransport at yah... Best of luck. Christina

I have a 1996 Jeep Grand cherokee with the 5.2l v-8 engine. Last week I started it, and it ran for about 1 minute before shutting off. The engine cranks, but no ignition. I replaced the Crankshaft position...


Time to meter voltage. Start with the 12V circuit. Are you getting voltage at the coil. Does the voltage fluctuate when the engine cranks? If yes to both check the high voltage circuit. Start with the coil then the distributor then each plug. You should be able to find where the spark is failing.

Why wont it start


Yes, it could be. The crank sensor is responsible for a lot of jeeps not getting spark. First check if the green/black wire to the coil has voltage with key on. That is the primary current to coil. If voltage there, it could be the crank sensor. If no voltage to coil with key on, then problem is that computer is not sending power to the coil. That will have to be checked-there is a relay involved-the Automatic Shut Down relay in the under hood fuse-relay box.

Engine won't start


If you turn the key to ON position and its not cranking at all,then its battery fault.If its cranking but not starting at all.That means the starter is also getting power.So if its cranks but not start then there are few possibilities to be checked.But if its not craning and no noise then battery and starter are to be checked.In other case :----

A jeep that cranks over but doesn't start, in many cases will be due to a bad fuel pump, a broken timing belt, an inoperative cam sensor or crank sensor. Also these problems are related to faulty spark plug. Check the spark at spark plugs when you start the jeep. Do you notice any spark. Actually you should see. If in case there is no spark then it's a spark plug problem. Also the coil pack gives power to spark plug. So check the voltage at coil pack. It will show 12 volt. If there is no voltage noticed at coil pack then its faulty coil pack that has to be replaced. If all the possible options checked out ok then check the jeep starter. The starter gets power from battery to start the jeep. If the starter is faulty then it will not let the jeep to start. Also check and confirm that there is fuel in the jeep. If its very low fuel then in some cases this causes the problem. Also check and confirm that fuel pump is functioning properly and the fuel filter is not clogged. One of the easiest ways to check for a fuel pump related problem is to spray a little starting fluid into the air intake while trying to start the jeep. If the jeep starts momentarily, then there's a good chance the fuel pump is not working or the jeep is out of gas. You can also listen for the fuel pump's humming sound when the key is first turned on. Also if a inoperative fuel pump is suspected, a good technician will always check to verify there is power and ground being supplied to the pump, to eliminate the possibility of a bad relay or electrical issue. Fuel pressure can be checked with a pressure gauge and if there is pressure, pulse can be checked at the fuel injectors in several ways including the most common, with the use of noid lights. If the injectors don't have pulse the engine won't start. ---------- This troubleshooting tips will help you to solve the problem. Thanks. Helpmech.

Crank, won't start problem. I checked the spark plugs on Jeep 98. Looks good. Could it be the crank sensor or starter coil?


Yes it is very much possible.But there are many other possibilities too,including starter and spark plugs issue.

If your engine cranks normally but will not start because it has no spark, or it stalls and won't restart because it has no spark.

You can also do a test to confirm the problem .The procedure to do the test is as follows:---

If your engine has spark plug wires, disconnect one of the plug wires from a spark plug and place the end of the wire near a metal surface on the engine. Then insert a small Phillips screwdriver into the end of the wire (the plug boot), or a small bolt or nail to provide a conductive path. Then crank the engine and look for a spark to jump from the screwdriver, bolt or nail in the end of the plug wire to the engine. If you do not see a spark, there is an ignition problem.

OR-----------

If your engine has a coil-on-plug ignition system with no plug wires, In that case remove one of the coils from the spark plug and insert an old spark plug, a spark plug tester or a screwdriver into the end of the coil. Ground the spark plug or plug tester to the engine, then crank the engine and look for a spark. No spark indicates an ignition problem.If the engine has no spark, check for voltage at the coil positive terminal when the ignition key is on. If NO voltage, then problem is on the trigger side of the coil (pickup, crank sensor, ignition module or primary wiring circuit).

But If there is NO voltage at the coil itself, then in that case the problem is on the supply side (the ignition switch or ignition wiring circuit).-----------------

Cranks but wont start


You need to check and see if the plugs are getting voltage/spark. If they are not then check and see that the coil is getting voltage. It sounds like you possibly have a bad coil. Something is causing your plugs to not fire.

1999 jeep cherokee does not start, tried cp sensor still no spark , batt. voltage at coil on one pin during cranking, coil checks ok with ohm meter.pulled up fault codes and there were none.


should have voltage on both posts of the coil. when the computer momentarly grounds the coil (in response to the crank position sensor sending it a square wave single). it will force a good coil to produce a spark. i would look at the coil again
good luck chris
