this is very normal.
All jeeps do this. when bad.
first off all engine stall when not tuned up or BAD.

same answer for 100 years running.
top of list is what, per operator guide, filters and spark parts.
see that list for 60,000 miles, its REAL.
now the normal bad deal
all jeeps 93+ have a feature, called ASD
this prevents crash and burn as een on TV.
and is by laws.....
you dont want fuel flowing with no spark. so...... ASD is born.
automatic shut down relay
NCABR (no crash and burn relay, works too){joking}
if you are tuned up, are you. and fuel fresh, is it?
then the scan tool told you why the ASD dropped ,did it?


there are really over 50 causes of stalls.
a huge list
we do simple tests, 1 to 10 and bam, the answer
a.k.a , gathering evidence.

do you want us to gue$$. or test.???
its your call.
the tests take tools. if working with no tools this will be expensive.
do the flash code tests yet.
sometimes this works, I dont like it, as key off erases some errors.

the key one off 3 times trick


one smart guy i know, got so grief stricken by this.
I do fell the pain
He bought a new ASD, for $10 (a relay)
then ripped the top off the old, he kinda skeletonized, it.
so it sill works but can see the GUTS (savvy huh?)
had son crank car, he watches it like hawk.
sees it close (as it starts, 1,2,3 seconds and BAM)
just one 1/10 a second, before the stall the ASD DROPS
now for 100% sure i KNOWS it drops
and knows 1 more thing, what is that,
answer, the PCM dropping it on purpose
and guess what, he now knows for fact the PCM recorded that error and the scan tool will see it.
my innova 3140 can. see the 93 to 95 errors.
96 year plus, all scan tools can..

lets not say the ASD didnt trop
that means the engine misfired so bad the ECU can not keep it running by adding fuel and more AIR (ISC) valve air.
its a bad running engine. and gets more complex.
but this is just the beginning in this case.

There's really not very much you can do because of it being a factory alarm you will have to take it to the dealer and have them check it. They may just need to reduce the sensitivity (if too sensitive cars driving by and set it off). If it is bothersome and you have to do something about it, you can disconnect your cars battery until you can drive it in.

Check the fuel filter,nozzles and clean the injector mouth

you may have a bad starter solenoid.using a test light at the starter the light should be lit on the large wire terminal and with someone trying to start the car yhou should have the light on when the key is turned to the start position.it you have a volt meter you should have battery voltage on the large wire and the same on the small wire when the key is in the start position.you can try tapping the starter when someone tries to start the car.if it starts then replace the starter.its the most common problem.

make sure the PCM numbers match or they won`t interchange.

1994 Jeep Grand... | Answered on Oct 27, 2015

Well ,then the PCM is not fine , send it back . Go to a salvage yard an get a used one . I had problems with PCM/ECM'S from them ! I have had better luck with used one's from salvage yard .

1994 Jeep Grand... | Answered on Oct 27, 2015

first off what is bucking? you never said, (engine or trans)????
there are may parts on the car, that can buck, shake, or surge.

the jeep keyon off on trick usually is totally useless for this problem. but heck free to try.
the problem here is the ecu forgets some error after keyoff. oops.. you need to scan it using a real scan tool....

if savvy and like danger
try to see if the asd drops, at the buck moment.
there are ways to do that. ask.
(bad dealer, fire him) try an honest , ASE shop and mechanic.
google "ase shops" BINGO !

avoid stealerships and only as a last resort. (a ride to h3ll?)
for that cash could buy a running used one. here.
it's an old jeep, and like all old cars they will be a problem.
all old cars are.
I'd have a scan tool connected, my INNOVA 3140 (does old jeeps)(this tool does old jeep OBD1 scans)

and see what codes are stored, DURING the buck.
that's right driving and scanning, wife drives, you scan... or?
if it's the engine, it will show something,.
ill guess, now,.... (useless)
1: engine bucks, actually its stalls and recovers.
the jeep has a THING, called ASD.
if the ASD drops driving it WILL BUCK, and is clearly not transmission slip, or trans gear shifts caused.
its engine, so focus on the ENGINE and EFI system
if you lose to fuel pump pressure its not a buck its a slow bog.
so its not the pump dropping off line.
its spark dropping. and the ASD does that on purpose.

read this.


what is something

if the ECU loses power, 12vdc main power,
the ECU goes off line and the scan tool shows. (lost comm)
bingo, no?
or if not that the ECU reports ASD related EVENTS (DTC'S)

I believe it's one of your relays too. There are a few relays under the glove box. If you can determine which one is clicking you can change it out and possibly solve your problem. Good luck...

Most likely with a vehicle of that age, the float assembly (fuel level sensor) in the gas tank has failed or has become disconnected (possibly lost ground connection). It is also possible that the gauge itself has failed.

It won't crank? Have you tried rapping the starter with a hammer-a light tap- to see if it will work? If that works, the starter is going out and needs replaced. Alternatively, take the starter off and have it tested for free at a parts store.

While you were filling the tank you may have disconnected the pump wires. If you can hear the pump activating when you use the switch then the pump may have gotten clogged , check for sediment in the tank.  For the person with the mustang - if its only coming out of one side then its a nozzle clogged or a pinched hose.
