1993 jeep grand cherokee laredo 4.0 no spark

pick-up coil in distributor bad. have to pull dist. take shaft out to get it out

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.

CHECK ASD RELAY THAT IS AUTOMATIC SHUTDOWN RELAY IN THE POWER DISTRIBUTION CENTER UNDER THE HOOD IN ENGINE COMPARTMENT.IF ASD RELAY GOOD PROBLEM COULD BE CAMSHAFT SENSOR IN THE DISTRIBUTOR.TO SAVE TIME AND MONEY HAVE JEEP SCANNED FOR CAMSHAFT SENSOR AND CRANKSHAFT SENSOR FAULTS.

Check the fuel pump,Clean the fuel pump sound like not getting continue fuel to the engine.

I don't work on Jeeps, but the Rangers have a power relay for the ignition. You might want to try asking at Autozone or O'reillys if the Jeep has any relays. It might be worthwhile to check the fuse panel to see if something blew that might control 2 or 3 things including the ignition. Hope this helps you.

It sounds like focusing on getting the spark then you can start the engine.You want to confirm everything works from the coil, so you can find out what causing the coil is not working. Here are what to check the coil before a replacement::
1- Disconnect the Positive cable on the battery.
2- Hook a spark plug directly to the coil wire ( the one to get to the distribution cap)
3- Find a long double wire so you can connect from the terminals of the primary coil to the battery.
4- Connect each wire end to the terminal of the primary coil. It doesn't matter which polarity.
5- Connect 1 wire to the frame ground.
6- Hold the other wire and quickly swipe it over the positive terminal of the battery. Reapeat it until are sure that you get spark or not.
7- You should see or hear a spark. If this is the case your coil is good. If itis not, your coil is bad and it need a replacement. Problem is solved.
4- If the coil is good, the problem would be from the Primary of the coil back to the ignition key: No electrical signal to turn on the coil.

Hope this can help.

you might need to change the distributor

check ignition pick-up coil and ignition module

Back up a minute...Do you have spark from the coil wire? (juice from coil) If so, change or check rotor and cap (wires do not all go bad at same time so unless they are wet, likely at least good enough to start engine)

OK...I have a 93 outside...one 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.)
