The crankshaft position sensor was seriously problematic in those old jeeps. It's located towards the top of the bell housing slightly to the driver's side I think.

    I always get to them from underneath with a looooooonnnnngggg extension and a swivel. I can't remember what size the bolts are but I wanna say 7/16. Chrysler though, is a little silly with their bolt sizes sometimes and it could be anything from 8 to 10 or even 13mm (they forget they're an american car company). You may be able to get to it from the top, but I've never tried. I know you can put your fingers on it, but getting tools to the bolts is a different story.

SOURCE: 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.

Could be a crank or cam sensor gone bad. I suggest you get a haynes or chilton manual and do the testing outlined in them to determine which it is. Neither item is very inexpensive and the crank sensor is a real pain to replace. There are other things that can do that so testing is important.
Crank sensor is the most common failure but asd relay, wiring problems, bad ground on a relay etc can do much the same thing.
Anything you find that you need further help with I'll be happy to answer if I can!
Good Luck!

1995 Jeep Grand Cherokee Sport it just won't start. It cranks, that's it. It was running fine yesterday.


If it was running yesterday and only cranks this morning you need to determine which you are missing - spark or fuel. The spark is easy - pull a plug and let it spark to the frame. while cranking. If you have spark then you have to start checking the fuel system.

First run a code check, see what you find. Second, you can do individual component testing with a decent volt/ohmeter to pinpoint problem. (instructions for tests in any decent manual)
Just off-hand, most common failure with similar symptoms to yours is crank position sensor.

Are you getting spark from coil wire when cranking? If so, check the cap & rotor. If not, the most common failure is the crank sensor. If you have a 4,0, you can find it on the drivers side of the bellhousing, in line with the flywheel, just where it's annoying to work on. There is a test you can make, but I don't have the specific test values or the correct terminals to check. (you can find that info in any half decent manual.
Good luck
