There would be salt formation in the radiator which would turn the engine off and also may be the spark plug would be weak so try to clean the radiator and change the spark plug also.

WILL START DRIVE A FEW BLOCKS , THEN SIT 5 MIN GO TO START AND WILL ONLY CRANK CHECK FUEL FUSE SOMETIMES BLOWN OTHER TIMES NOT HIT TANK THEN MAY START , MIGHT TURN OFF AND THEN MAY BLOW FUSE, REPLACE FUSE...


for 1 fuse blown evry so often then you must have a short somewhere, the fact that it will crank and not start is most likely ur fuel pump , had the same issue with getting fuel to start or keep car running, possible that short could be by the fuel pump, the fuel pump is located under the rear seat and if im not mistaken it is on the drivers side rear

93 jeep cherokee 4.0 dies when stopping but idle till fuel gone


GREAT INFORMATION...

however, you were not clear about fuel pressure

was fuel pressure OK before and during the concern...30psi and have you check flow

PLUS...during the concern are you loosing SPARK? Coil is great suspect!

while the code for the crank sensor concerns me I'd start with the most common Jeep concern...the ASD (auto shut down realy)

when you start testing again remember to check the CKP output at the sensor and the CKP input at the computer...you might have a CKP circuit that is worn out

depends on how many miles on the car,,but sounds like timing chain,,but be careful,,if u have a ( 0 ) tolerance motor something could of happen internally,,2.3L are known for timing chains,,unfortunately u wont know this, until the head is removed or chain is replaced

1984 toyota pickup, 22R engine, stalls out when driving 2-8 miles


I had a similar problem and it turned out to be the rubber fuel lines being old and cracked. The hoses would warm up and fuel would squirt out of the cracks. I had to replace three fuel line hoses and it has been running great ever since. Good luck.

Engine shuts down on deceleration


Well 145K is alot of miles, catera's are not that reliable especially after 100K. It sounds like you could have multiple issues but take it to a mechanic asap before it becomes unfixable.
