Ok , I have the same problem, I was told to replace the ignition module i just ordered it. also a friend of mine works at a dealership and he said this is very common on 97 sports, The computer goes out, cost 214.97 to replace i had the same problem and the a mechanic said it was the computer, but i still thought it was a crank sensor. i replaced the crank sensor first and the Jeep runs great. My 98 with the straight 6 did the same thing, and the mechanic at the dealership told me I needed a new computer without looking at it. A friend of mine with an computer reader plugged it in and found both a bad crank sensor and a bad O2 sensor (not in that order, however), replaced both (one at a time) and it runs like new now, even if it has 120k on it.
I was browsing for the same info and came across this article. http://www.asashop.org/autoinc/feb99/techtotech.htm I think is worth reading because I spent a lot of money/effort/hours on the problem that I had with my '95 Cherokee (which was almost the same you have). Good luck solving it
it could be the coil pick up in your distributor
Yes. The Crank sensor monitors the position and rotational speed of the engine to determine timing for ignition. if it is not functioning you will get no spark.
An ignition coil is an coil that is used to change the volts in a battery to ignite the spark in the spark plug. This is necessary to get the engine to start up and the car to run.
Check to see if you are getting spark (coil) and fuel
It could be in need of a new set of ignition wires (spark plug wires).
plenty of things could be a starter, alternator, ignition switch, bad spark...
there are several problems that could cause this on a jeep one is the ignition switch, the starter, the gear changer on the transmission.
A bad ignition coil will cause your engine not to have any spark. Without any spark the engine cannot start or run.
If it is getting fuel, try a new spark plug. The old plug could be fouled.You start by determining the reason why it won't start. Ignition, compression, and fuel... you need all of them in order to get the vehicle running.
neutral lock out switch It really could be several things. It could be spark plugs it could be no gas it could be no oil, and more. it could be your battery, starter, coil.etc
Depends on the motor, 4cyl or V6, but it could be the ignition module, or the crank sensor
It could be the coil - it could be the spark plug. If it has electronic ignition it could be weak
The most common failure associated with those symptoms is the Crankshaft Position Sensor.
There could be a few reasons why a 1990 Chrysler Lebaron will crank but not start. The fuel pump could be out or the car could be out of gas. There may be a malfunction in the ignition system causing no spark.
If the vehicle turns over but does not start, check for fuel pressure, and ignition spark. If the vehicle does not turn over, then the starter system could be the problem.
You could be out of gas or not getting fuel to the engine, or you could have an ignition problem. To check for spark to the spark plugs - remove one of the wires from one of the spark plugs, then put a large paperclip in the wire and hold it just above the engine where you can see the spark jump (I would hold the plug wire with a pair of rubber coated pliers), crank over the engine - if you do not get ny spark then you have an ignition problem. Check the ignition points under the distributor cap, they may need to be set to the proper gap.
Maybe the starter. Does it click when you turn on the ignition? Yes and also check to see if you are getting spark and there could also be a fuel delivery problem.
Does it turn over? Check for fuel and spark--could be bad fuel pump or bad ignition coil
You bet. A bad coil and you have no spark to the plugs. No spark and the fuel cannot be ignited.
my car no start I check the spark ignition on the wires an they don't have how can fix the problem....
Several problems can cause a 1999 Blazer not to start. There could be a fuel problem or a firing problem. Check for fuel pressure and ignition spark first.
Does it turn over? Does it have fuel, spark and compression?
Check for loss of ignition spark. Weak or no spark will cause the vehicle to not start. Check fuel pressure if the spark is good.
It should be on the drivers side underdash. here is a large group of wires under the hood that bolts up to it. Culprit could be an ignition pickup or PCM. Do you have spark and does it stay sparking or does it start to spark and then stop?
check the spark plug ... do not start it by bushing the fuel pedal . just start it by doing nothing els ...
