    I have a 1994 JGC and I was driving in commute traffic and it just turned off after that it never started again. I took off the cap and rotor which i replaced about 6 months ago along with the wires but everything looked fine so then i pulled the coil wire and i have no current going to the coil at all. I checked all fuses and relays but can't seem to locate the problem.

    Thanks

    I am having the exact same prob. my jeep won't start there is no power going in to the coil. I ran a jumper wire from the auto shut down relay to the coil to see if i had a broken wire but still wont start.

    When I would drive down the road it would shut down and after a few min. it would start. Then I was getting gas filled it up and it wouldnt even start. So I changed the coil, crank senser, and it still wont start. I havent checked the pickup in the dis.

I had a problem similar to this. It was the crank sensor. It bolts into the bell housing of the transmission. If it is bad the jeep won't start.

Check your starter wire as mine was loose and did the same thing every time you interupt power to the alarm system it will flash the lights unlock the drivers door with the key and this will rearm the alarm and the jeep should start up if this is the problem rember to have good battery conections and a good batt first or else this will keep hapening also after 20 starts you may have to do the key thing again

You sure code is 32? I never heard of a 32?? First, start with simple...Is there spark from plug wires when cranking? is there spark from coil when cranking? If not, is there power at the small (+) terminal on the coil? Is there an ignition control module mounted next to the coil? Has anyone checked the crank sensor or the pickup inside the distributor? Is there fuel? after cranking is there wet fuel residue on spark plugs? If not, will engine start briefly if you spray carb cleaner or starting fluid into air intake while cranking? Does battery have sufficient charge to spin engine over well? After numerous no-start crankings, it may loose some charge (sufficient voltage is necessary for systems to function properly.)
These things must be checked before you can determine the correct path to follow...Flailing around will cost $ and unless by accident, will get you nowhere. I'll try to help but you need to first check these items and post results!
good luck

    The poor rating you gave my response made me sad...I gave the same advice that I actually would follow if I were checking your vehicle.The fact that you are a woman is irrelevant to me as the vehicle does not know this, nor would it care. The two code books I have don't show a code 32...codes are guides, not definite answers. For example, if air flow is restricted or too much fuel is entering the engine, the code for an O2 sensor may appear.There is nothing wrong with that sensor! It is getting info that is beyond normal, and cannot "read" it properly. But as a GUIDE, the code would be useful to point you in the right direction. A novice would change the sensor and still have the original problem.
    I hope that someone has repaired your vehicle and you are back on the road!!!
    That's the point of this in the first place!!!
    Good luck

    I really care about the solutions I offer here...If you decided that my outline of what to test was inappropriate, so be it. BUT, in not posting what actually cured your problem, no one learns anything...What was the actual solution to your problem??? (your answer can help lots of other people!!!)

Jeep cranks but does not start


Hi, First replace your plugs. Second check ignition coil(s) one maybe bad. replace with new. If all else is good, have your mechanic check the computer codes. (code scanner) Many of todays cars and trucks have computers to run and control the engine. (management system). Good luck

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).-----------------

Ok I have 2002 Jeep Grand Cherokee, I have replaced the spark plugs and the coil rail but still getting the code P0351 and I was wondering if this could be caused by some kind of sensor?


The code indicates the coil pack or spark plug is malfunctioning. You can test this using an additional person. by removing the coil pack and spark plug, place the spark plug into the coil pack and ground the tang on the spark plug to the engine. Have someone start the engine and watch for a blue spark. if there is no spark, then the coil pack is malfunctioning. There is also ways to check the coil packs using a multimeter.

also, bee sure you didnt crack the ceramic part of the plug during initial installation.

94 Jeep Grand Cherokee heater coil has been replaced wont start


If you have a security system, close all the doors and then lock the drivers door with the key, then unlock it. That should re-set the system. I've had the computer completely disconnected from mine several times (used it to check another vehicle) and I don't have security...it started and ran fine...only difference between the two is the security so I'd try that.

I have a 94 cherokee coutry w/inline 6. When I


First place to look is in the wires from the battery to the starter and the battery to the ground... got corrosion? this can really choke off the flow of electricity to the vehicle... check both ends of the starter cable and the ground from battery to frame (or block or trans) any kind of green or white deposits indicate it's time for new ones... this can be tricky because the corrosion can be inside the insulation on the wires... if corrosion is bad enough even a jump won't start the vehicle as not enough voltage will reach the coil... if the wires are good then it's time to check the coil and it's wiring... if you aren't real savvy at testing components with a meter then replace the coil (assuming good wiring) and test for spark by holding coil wire about 1/4inch from the block or any good ground while turning engine... you should see a nice blue spark... hope this helps...;-)
