Is the ASD relay dropping out.???????
ever do a tuneup this decade,??? spark parts, filters,????
if the ASD dumps, here are the 7/8 reasons.
click ASD seen on this page.here.

AutoMATIC SHUT DOWN RELAY.

on other cars its called MAIN. but jeeps its ASD.

on 93s this is old. but is OBD1 compliant.
but there is 1 scan tool that works it's mostly a code reader, but as you may not know, the key on 3 times trick
will hide the DTC that caused the failure. (lost spark is hidden, oops)

so using a real code reader, you can see what happened in real time.

Sputtered out and now it won't stay running; dies when put in gear.


Mass air flow , crank sensor . I wouldn't discount anything . Having a scan tool that can view engine sensor data would be a great help too , testing fuel pressure and flow and back pressure test the exhaust .

It won't die when pulling the relay because it has another power path to the fuel pump through the oil pressure switch . Fuel Pump Electrical Circuits Description and Operation watch this video on fuel pump control , shows chrysler first , ford ,then gm . wait for gm an he explains the oil pressure switch . Plus when it won't start ,don't guess or theorize ! Test what's missing ? check for spark , no spark check ignition system , coil's , ignition module , crank sensor etc... has spark ,do a fuel pressure test etc... don't think computer , when it won't start does the check engine light come on with the key on run not start . If light is lit ,nothing wrong with the cumputer . If want to fix cars you really should take some automotive classes . Test don't guess .Watch some other videos crank no start videos etc...
