    i have the same problem. car starts and i can drive it for about an hour. then i have to wait 3 to 4 hours in order for it to start again. I changed the relay, fuel filter and put fuel injector cleaner. feels as though something is clogged.

Mine will run for a while but it dies. then it won't restart. the problem is 99% of the time in the distributor. there is a pickup coil right in the distributor casing. only some heat up and have problems. yours is more then likely faulty. they go for $170 - $250. so go on eBay and you can find a whole distributor for $85, this is very cheap. it is re manufactured and guaranteed. good luck. call Nissan and they will tell you the same diagnostic.

Autoshutdown keeps turning on


which engine???????????????????????????
ASD is tricky on jeeps.
The Auto shutdown,relay.
what is it , how does it works is covered in the fsm. read it.
http://www.jeep4x4center.com/knowledge-base/index.htm?utm_source=cj#service
The ECU runs this RELAY, and if the ECU sees a gross error
it shuts this down, and the schematic there is clear as to what.
both spark and fueling.
here is what can drop it out.
1: crank sensor.
2: cam sensors or TDC ,etc.
3: sees spark dead or weak.
4: Immobilizer active. (failed)

as the book says , make sure spark is good for the 2 seconds cranking. (not after the 2seconds)
the ECU is programmed like this.
user cranks.
ECU creates spark,, using the crank/cam sensors at the time base
for 2 seconds
if the spark read back fails or the 2 sensors fail, the ecu shuts DOWN.
this is for fire prevention.
most other cars just cut the injectors, but not jeep
the drop the MAIN ASD relay.

using the check engine light flash codes, you can see which of the
3 failed, cranking for 5 second and releasing the key on all cars.
1996 and newer a scan tool is use to same effects.

now the 64,000 dollar qustion,
see page 8w-30-4
why does the ASD KILL THE IGNITION coil. easy.
1: it only guess it 2 seconds to make spark
2: if it cant,. it then drops the relay. killing fuel too.
3: this prevents the the crash and burn you see on TV.

so its 2 second permissive system. (or 3?) i forget exact seconds, its in then book and is short.
many dont know this. but is a fact.


now the flash codes.
crank for 5 seconds while in flash code mode
see emmisions page for how.

flash code 11 drops the ASD ! (cam or crank sensor dead)
code 54 cam signal dead?
code 43, spark bad.

sounds like a bad cam sensor. have scanned if light on dash is on. if no scanner any auto parts store will scan for free. a bad or failing crank sensor will make vehicle stall out after a few seconds or minutes. if it is bad enough it will not start. because it controls timing.

WONT START WHEN COLD CRANKS FINE. HAS CODE 54 CAM


ok, any obd code means the sensor concerned is not detected by the ecu, or is way out of range of the normal signal the ecu expects. I would therefor check the electrical path between the sensor and the ecu terminals, it may be just a chafed cable or wire.

You have to find out if it has fuel and spark . One or the other is missing at the demise of the engine.

1995 Eagle Talon Will not start


check the mass air flow sensor, if this is bad then the ecu wont get a signal and it wont send the right amount of fuel to the cylinders causing a no start condition
