Check the ASD Relay! Try pulling the relay, look on the side of the relay and it will have a diagram, your looking for the two main hot feed wires, one will be 30 and the other will be the one straight across from it, I can't think of it's number.
Anyway, get a short piece of wire and clean each end and bend it so it will fit in where the two prongs of each of them numbers (30 and **) went and try to start your Jeep.

Before you insert your wire into the slots, make sure you pay close attention to the diagram and how the relay fits into the slots!
By the way, this ASD Relay is located under the hood in the main fuse block.
My guess is you have something causing it to shut down that relay or possibly a bad relay, if the relay is bad you can try swapping it with another relay right there just make sure it is one you do not need to make the Jeep run like the a/c relay.

replace the fuel pump,the check valve that holds pressure on the fuel is in the fuel pump.The fuel in the lines is draining back into the tank

Good luck and don't drive too fast.

Check out the EVAP system to see if you have a broken charcoal canister or cracked vacuum line. Also check for vacuum leaks.. Those would cause hesitation, stalling. Read this post on EVAP

You don't need a scanner. If you cycle the key off and on 5 times, the codes will start flashing. Here is a link to jeeps and their trouble codes. There aren't that many in the older OBD-1 systems.

If you have no trouble codes, check fuel pressure. Multiport injection is high pressure, above 40psi, but Jeep would have specs.

you need to check the voltage at the battery when you have trouble. should always remain above 12 volts.
If not then the battery or the connections are bad. first test the battery right at it's lug terminals, then check the terminal connectors. battery or cable or connectors - def sounds like major voltage issue in the battery area!

It's 25A FUSE 12 in the fuse/relay block.

Well, other than the pump, I would say nothing, because you said you can't hear the pump prime when you turn it on. Unless you have a wire loose or fuse blown.

lots of guessing.

old car, but is Chrysler made, good that. 93+

ok, the car has a cel lamp. is it glowing running\'?

this is called misfire. is the engine stalling?

on all cars that old the first thing do is check compression.



the rules to end misfire are this (a full tuneup)

fails

1: compression all the fuel and spark in the world can not run dead cylinders. ever.

2: then spark, check that all spark plug tips are clean and the spark is strong. then check timing, if any thing here is wrong fix that next.

3: fueling this is complex and is always last. after spark.

I6 4.oL is nice motor owned 3 since 1988. zillion miles on them.

unlike 88s your\'s dont suck. mine had horrid french RENIX EFI......

nasty that..... is...



so you do the flash test on the CEL yet, see if you have DTCs stored.

if not why not? this be like first. its free, and is very helpful

if you have DTCs/ stored. DIag mode is activated with.



put the key in the ignition and turn the key to run (not start), then off, then run, then off, then run (that\'s 3 runs and 2 offs). Leave the key in the run position

count the blicks, best done just after misfiring.





fueling is complex.

6 injectors that can leak ,or clog.

the test is called a injector balance test. but is never done

before the 3 fuel pump pressure tests and the 2 regulator test

never. are those to be skipped and the tool is $20 lousy bucks.

if you get this far , we can do fueling all day. long.

but we also check all sensors for valid inputs.

as all ECU puke with bad inputs, all computers for that matter







saying good fuel pressure means zero with EFI, ZERO

only PSI matter.s not squirt tests. or other dribble tests.

those only proves pump is not 100% dead.

how , you mean step by step. (itty bitty)?
well it does so just like all cars.
the coax, (called consentric) has a bleed tap right next
the the fluid line as it enters the bell housing, did you even look yet.

is this the COAXIAL salve/throwout, same as the 93?
read the real FSM

https://www.techauthority.com/en-US/Pages/Home.aspx

why not post the symtoms, btw ive owned 3 jeeps with the coax,
yes, i hate them. had to pull tranny and transfere case or engine
to fix them.
read YJ, page clutch page
here
http://www.jeep4x4center.com/knowledge-base/index.htm?utm_source=cj#service

page 14 covers it.
it bleeds exactly like brakes. after all it uses brake like MC and slave.
so you do the exact same methods.
use the 2 man methods.
fill it up.
keep it full.
person one presses the pedal , you crank the bleed valve.
and air comes out, you close valve
pedal up
and repeat for no air,
test a book on brakes , it not changed for 100 years the 2 man method.
there are 5 methods, but the 2man is 100% free.
just a hose to catch the juice.

run the fault codes. check the serviceability of the cat converter as it may be broken inside and blocking the exhaust

If bulb or socket melted then replace socket. May be OEM part not sure. Easy fix just be sure to use seal type crimp connectors or you will be working on this a year later.
