1993 jeep grand Cherokee Larado stalling for no reason. we have looked or changed coil, fuel pump, relays, cam sensor inside distributor, this thing still stalls out, but starts right back up.


Crank sensor. Its on the passenger side on the top of tranny. Will have either 1 or 2 10mm bolts holding it on. And a plug. My 94 had the same problem. It would run fine then you shut it off and all it woild do is crank. Wait like an hour and it will start back up. New crank sensor and it was fine

I have a 1993 jeep grand Cherokee Laradeo and it is not running. I have installed a new fuel pump, and crankshaft position sensor. It has good spark but it still isn't turning over, any ideas?


Does the check engine light on your dash light up when you turn on the ignition, before trying to crank the engine? Does the fuel pump come on for a second, and prime the fuel lines, when you turn the ignition on? Does the fuel injector wires get the pulse signal from the ecu while cranking? If not, your jeep ecu might be in need of repair. It's a common problem with that generation of grand Cherokees.

Transmission


Possible that the lockup converter has locked (a bad thing)
There are several other things it could be but that's the most common & what came to mind when I read your post. Sorry I can't give you more on this, but you need a reputable trans shop lto take a look!!
Good luck

Car will not start


If this is a six cylinder, there were problems with the fuel pressure regulator leaking gas into the vacuum line creating a flooded condition. You might want to check map sensor,crank sensor.
