yes but not the right way to do it

I recently repaired my non-working 1995 ZJ VIC by reflowing the solder on the wire connections to the circuit board, and other cold solder joints.

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.

Are you getting spark at your plugs?

is it all time 4x4?

Have a shop look into this and repair it the right way, stop throwing pumps on this, do it right find the route cause.

is this a how to diagnose it question or a kids guessing game. we can guess all day, even all week, your CALL ! 1993 still running a "Kodak moment"? wow. that is called MISFIRE, there are over 50 cause of that. are you going to guess up to 50 + times> ? id hope not. and all misfire causes engine power loss, (all) ZJ jeep 3 engines, 5.2L is yours. ever put in new spark plugs??? in last 10 years? you cant burn fuel with bad spark so this is like #1 for 100 years+ gas engines.... test 1, can you save the stall, with a fast right foot if no, the you lost 12vdc to key EFI parts or its fuel problem this be 2nd after new spark parts, (a tuneup is always first of owner does NOT do proper service) why spend 4 hours shop labor only to find , omg,100,000 mile old tuneup parts, (big cash to learn they dont last a life time)??? TUNEUP? filters (both) spark plugs. if those old ratty spark wires are 24years old, they are hopeless distributor cap, same thing distributor rotor same. if it still misfires, it can be injector problems. (lots of tests here) even engine cylinder compression low, we always check 90s cars for this, after all its OLD. generic, data; on 5.2. 9.1:1 CR sea-level spec only. 150psi x8. wide open throttle or more. read data shows 1993-1998 Grand Cherokee. 5.2L v8 9.5:1 CR, 180 PSI ask how to do that test correctly. This 1993 the check engine lamp can glow, running? if it is? , it must be scanned to find the codes, DTC errors Innova 3160 tool can do that. or most good shops. or even the Actron CP9145 (used onlY) the latter tool is the Bee's knees on old cars. with EFI.

I don't know engine size? The fuel pressures I found was 31--39 psi, 92--95. I would use a gage and check proper fuel pressure. How long since over-all tune-up? Any applicable trouble codes?

ever do a real tuneup this decade spark parts, and filters. that be first and make sure the hot engine (sized not stated) is really hot. 180F or more, and holds, it must reach normal spec, temp. or the ECU brain will not do its job right. the only clue I have here is skips skips must mean misfire. there are over 50 causes of misfire. bad spark plugs tops the list. and all spark parts there, cap/rotor,wires set this OLD. car is old , needs a major tuneup they to forget all that other stuff, and elaborage what skips means. i guess never cold does it skip. taCH DROPS TO ZERO BUT engine not heard to stall? if yes, electrical problems or CKP failing? what does engine do when TACH does that, matters big time.

the first good GC... 93, and a good start. but is old i read that 3 times, and draw a blank, try to tell what works an dont, tottally like what your mechanics sees, he sees all. all things good, bad and ugly, all at once. there are key fobs and there are door on door locks. and not just one.

wow no engine size stated, the 5.2L run a special trans... so.... hopeless to help you much. zj jeep with automatic. it didnt lie, it told you to service it, so take it to a shop and let the work on this old dog.. stuck , now what does that mean. the shift lever lever stuck, or its cable failing end to end.? or? or shifts from 1 to 2 and hangs there. or down shifts from 3 to 2 and and hangs there DIY ? question is that it? you never said intentions..... so we open the 93 ZJ book and what do we see. ax-15 stick box, seems not. the aw-4 auto , electronically shifted with TSM (scan it yet?) and the 46RH auto. used on the 5.2L, has no TCM brain. its a Hydramatic. here are the OD words off the 46h page Overdrive Control Switch The overdrive control switch is located in the instrument panel. In the On position, automatic shifts into fourth gear overdrive will occur. In the Off position, the switch overrides the powertrain control module preventing a shift to overdrive fourth gear range. The switch has an indicator light that illuminates when overdrive is turned off. The switch also resets when the ignition key is turned to the OFF position so that the automatic overdrive feature is restored. The use of fault codes is employed to help diagnose the electronic components that operate the overdrive unit and torque converter clutch.
