1994 jeep grand cherokee doesnt like to start when warm


Car not starting or turning over indicates towards multiple possibilities. It can be issue with battery or weak battery. But if battery checks out ok, then it can be starter issue or faulty alternator or problem with low fuel pressure or no spark at spark plugs due to dirty spark plugs or faulty ignition coil or injectors getting cracked or dirty and needs to be cleaned.


To confirm the problem, the basic troubleshooting is required.

1993 Jeep Cherokee 4.0 turns over no spark.


Most common cause of this is a bad crank position sensor. However, do not change it before testing. Test between the b and c terminals of the connector with a digital volt ohm meter (set to ohms) You should read an open circuit there (same reading as if both leads were not touching each other and the meter was turned on) Anything different means it has failed. If it checks out as good, then get yourself a chiltons or haynes manual and follow the test procedures outlined in them. Worst thing you can do is start buying parts and hoping it will solve the problem. If you do that, likely, you will have an engine with lots of new parts that still does not start.

No spark 1990 jeep cheroke


take your ignition module to a car shop, the shops i know all have these testers.
i do think its faulty but get it tested.
i test them by using an oscilliscope, very expensive.
if not sure i then tset the phase sensor, i dont think you can as im sure a multimeter wont go low enough
on module, you have a 12 volt supply, earth, then phase signal, then a 5 volt amplified comes out.
get a meter and stick on to low tension on coil.
12 volt when on
5 up and down when cranking.
if very low it is the module or power to module
more likely module.
if in doubt get back to me.

Engine turns over but won't start 2001 Jeep Gr. Cherokee 6cyl


Start with the control module,I think it is located under coil on this model,You have checked the rotor to see if it is turning haven`t you?If it is not you may need a timing chain.

No spark from ignition module on hot start


95 JEEP WRANGLER 4 CYL

No spark. I have changed out the distributor cap, rotor, wiring from coil to cap, and coil was replaced. I checked the distibutor by turning ignition key and observing the rotor turn. What else can I check. I did not observe a module.

94 Jeep Cherokee won't start


I believe the green wire is a pulse from the distributor and its a ground signal. I could be wrong since is been a while since i left the jeep dealer...I would take the coil out (2 bolts on most) and take it to autozone. They can test it in minutes for free. Either that or the ignition module but more common is coil.
