1992 Jeep Cherokee starting problems

Check the ASD relay ! powers injectors .Located in the engine compartment power distribution center ! ASD auto shut down relay . Very common problem .

i guess, you meant , engine issues, engine cranks ok , starts then stalls right?
that is cause (most times) by the ASD relay dropping out.
is it? dropping just before the stall?
if yes, the scan tool will tell you why, there are 8 reasons...
all documented in all jeep 93+ FSM books.

does car have Immobilizer option?
if yes, that too will drop the ASD so (bad boys) cant steal it.
so if the immo light (generic name) is on or flashes before cranking or during cranking, then the IMMO is UNHAPPY.
again scan it.
if yes, IMMO did you try both key fobs, as came with new car?

if the ASD does not drop.
the that can be 50 reasons... a huge list.
major engine parts.
never had a REAL tuneup in a decade? (spark bad)
lost spark
bad engine.
bad fueling (too much flooding or too weak or none)

if engine floods?, crank with wide open throttle per operators guide.

Relays usually connected with abs-asd-lamps-fuel pump-engine start systems-located on power distribition center (pdc)

gee 1, last year of Cherokee is 2001, so you meant Grand right??????
gee2, wont start or stalls, no other symptoms????? just 1 DTC, no others using a real scan tool? that be first huh?
Geewise 3, what engine, wow, wrong car, no engine or country.?

the FSM covers this, and the ASD has 8 ways to trip off line'
UP TO 8 ways , just like old wonder bread had.

answering for 2004 GC, (i actually look it up in the real book)
not google butchered DTCs.
P means power train, 1 means factory codes.
a 3 coin toss lands...
2004 GC, vin N, 4.7L v8 automatic,


it reads. verbatim.
Trouble Code: P1389
No Auto Shutdown Relay Output Voltage To PCM
Number of Trips to Set Code: 1

• Catastrophicmonitor failure.

Trouble Code Conditions:
Engine cranking; and the PCM did not detect any voltage on the ASD Relay Output circuit to the PCM during the CCM test.
Possible Causes:

1. ASD relay connector is damaged, loose or shorted
2. ASD relay output circuit is open between the relay and PCM
3. ASD relay power circuit is open (test power from Fused B+)
4. ASD relay is damaged or has failed
5. PCM has failed (nah)

it means, to me.

• the relay is unplugged
• or fuse blown "fused B+" (a top reason, world wide)
• the relay is bad.

my buds ASD page,

great question the ASD, a key relay to sustained starts and running.
and told the engine, bravo !!!
post the DTC error code.
The ASD can drop out for many reasons, post all DTC codes
and never forget, crank for 5 seconds then look for DTCs
and pendings....

see wiring page
see PDF page 22, BINGO.

Sounds like maybe the relay is not working. Posible causes might be a bad relay, no power to the ralay, a grounded wire from relay to the PCM (computer) ect...

It could still be the battery....It may not be strong enough to start it but you will still have enough to operate windows and radio....It doesnt take much power for radio....or windows Unless you move the windows constantly then it will run battery down quick.....Check battery voltage and battery connections...Also jeeps have a ASD relay which means AUTOMATIC SHUT DOWN...This could be a bad relay.........This is under hood at fuse Power Block Box.....This could of course be the starter also...Check wiring connected to starter....Sometimes it will vibrate loose and it will do nothing....And the crank sensor will cause it not to start....It is on the passenger side of engine block under and at back of engine ...You cant miss it if you can get under it.....It has another relay the same size as the ASD relay...You can test the ASD relay by switching the two and this will tell you if the ASD relay is blown...If this doesnt change anything and still wont start it is not the relay.
I am chrysler tech and have jeep manuals.......I can help you through this....I need engine size and exact problem....Does it turn over at all ?..How many miles on it ?..And does the dash lights and gauges operate when you turn the switch on like normal...?..Make sure it is in park and your foot is on the brake while turning it over.............................................Metalpoet

-check the fuel pump relay and the ASD relay, both relay located in the engine compartment near the battery.

CHECK ASD RELAY THAT IS AUTOMATIC SHUTDOWN RELAY IN THE POWER DISTRIBUTION CENTER UNDER THE HOOD IN ENGINE COMPARTMENT.IF ASD RELAY GOOD PROBLEM COULD BE CAMSHAFT SENSOR IN THE DISTRIBUTOR.TO SAVE TIME AND MONEY HAVE JEEP SCANNED FOR CAMSHAFT SENSOR AND CRANKSHAFT SENSOR FAULTS.

Try resetting the asd "auto shut down fuse had a similar problem the jeep would crank but did not get spark or gas also check your fuel pump? and the asd relay may be bad it will prevent the jeep from getting no spark and will not fire some jeeps have security problems
