Question about 1993 Jeep Grand Cherokee

Open Question

1993 Jeep Grand Cherokee cranks but won't start. Changed the spark plugs, hooked up cps with multi meter and got a read of .78k ohms. I asked the guys at auto zone if this indicated the CPS was bad and they said no. The alarm would go off randomly before this problem. Any ideas how to fix?

What could be wrong with my 2001 Jeep grand cherokee 4.0? It cranks and cranks but won't start. Gauges don't move and key light on dash has line through it. Changed CPS and cleaned battery terminals a

Is it out of gas? Try spraying starting fluid into the throttle body and see if it starts then. If so, you have a fuel delivery problem. If not, you have an electrical problem (no spark).

Replaced cps,distributer(cap,rotor,cam position sensor)checked coil good still no spark,replaced coil wire and plugs is the computer next?ignition control module is in the pcm i think

If the check engine light does NOT come on when cranking at the times when it won't start, then your ECU is in need of repair. The engine will only start after the check engine light comes on and the ecu is what controls that. It's likely going bad, causing the delayed start problem typical of early 90's jeeps. Repair or replacement services for your jeep ECU are available on ebay.

1993 Jeep Grand Cherokee Laredo 4.0L 6L Auto Trans. Turns over but wont start No spark on plugs, good compression. Just put new ignition coil, rotor cap plugs plug wires. but, checked power supply to coil...

Check for a signal at the ignition coil with a node light or a 12 volt led test light while cranking. Check for a signal at a fuel injector connector jack while cranking. If both these signals are missing. Ignition and fuel signals, then the problem may be some common point. My 've will loose both these signals if there is no crank shaft signal or position sensor. CPS is on rear of engine, on transmission bell housing. Check for connections of PCS.

I have a 93 jeep grand cherokee larado have replaced alternator, starter, battery, coil, still has no spark got power to everything coil has power at it but nothing comes out of it repaced cap and rotor...

The only thing left to replace would be the electronic trigger module which is mounted inside the distributor. If this module is bad it won't switch the coil on and off to produce spark.

My 93 jeep cherokee just stopped running fuel pump kicks on, new plugs and wires.... will cranks and crank but actin as if its not getting any fire or fuel any ideas? I will broke replacing...

In reality, the best and only absolute method of doing a good diagnosis is to get a chilton or haynes manual and a multi-meter and going through the necessary component tests outlined in the manual.
If I were pressed to make an educated guess, I'd bet on the problem being either the crank position sensor or the cam sensor being bad. (most times cps). CPS is on the drivers side of the bellhousing at about the 11 o'clock position even with the flywheel and cam sensor is inside the distributor.

Replaced starter still wont start soliniod good 90

if the motor turn over but will not start try looking at the cps(crank position sensor)it would create a no spark condition. its located at the back of the engine right at the bell housing for the can test it with an ohms meter or just replace it.

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.

OK...I have a 93 diagram I have shows an ignition module next to coil...but there is none on mine, (4.0 engine)
Two items to check are crank sensor and cam sensor inside distributor. Test procedure can be found in just about any manual including haynes.
You will need a decent volt/ohm meter to do testing. You can also check codes by turning ignition switch on/off three times, leaving it on the third time. Check engine will flash code #'s (ex: one flash, pause two flashes= the number twelve.then followed by a longer pause then another set of flashes etc.)
