My Jeep stalls and will not restart after 3 or 4 hrs. Of driving off raod on hilly Terrain

Next time it stalls don't wait -look for fuel and spark immediately-refer to this link: https://www.2carpros.com/articles/car-cranks-but-wont-start

TAKE A CAN OF STARTER FLUID WITH YOU TOO

AFTER YOU CHECK FOR SPARK. IF YOU HAVE SPARK

SHOOT ABOUT A ONE SECOND BURST OF STARTER FLUID DIRECTLY DOWN THE THROAT OF THE CARB

ATTEMPT TO FIRE HIM UP. DOES IT TRY TO BUST OFF. OR IS IT STILL "DRY" OVER AND OVERS. NO SPITTING OR SPUTTERING. IF WE GET POSITIVE RESULTS FROM THE STARTER FLUID. WE WILL INVESTIGATE FUEL ISSUES

I HAVE MANY PICS AND CAN GUIDE YOU THRU CHECKING THIS STUFF. LETS NOT GET TOO FAR AHEAD AND COMPOUND THE PROBLEM!

IF WE DON'T HAVE SPARKRIGHT OFF THE BAT WITH WHAT YOU HAVE POSTED THUS FAR.I THINK THE 1ST COMPONENT I WOULD GET TESTED IS THE IGNITION MODULE

DO NOT PRY ON THE CONNECTORS WITH SCREWDRIVERS---GRAB THE WIRES ON EITHER SIDE AND JUST STEADY-PULL HARD TO DISCONNECT IT

HAVE IT TESTED 5-8 TIMES (NO MATTER WHAT THEY MIGHT SAY)

WE ARE LOOKING FOR A PASS--EACH TEST

THIS IS THE MACHINE (1ST PIC AT ADVANCE AUTO PARTS---THIS MACHINE CAN BE USED FOR MANY DIFFERENT MODULES. THE CORRECT CONNECTOR NEEDED TO TEST YOUR MODULE IS ON THE LEFT SIDE OF THE MACHINE IN MY PIC.I LAID IT THERE MYSELF!

I AM ALSO ASSUMING THIS PUPPY IS PRETTY MUCH STOCK AS FAR AS THE ENGINE GOES. LET ME KNOW WHAT HAS BEEN CHANGED. PICS ARE NICE!

LET ME KNOW WHAT KINDA VACUUM DIAGRAM NIGHTMARE YOU MIGHT HAVE TOO, I CAN HELP YOU MINIMIZE IT DOWN TO JUST WHAT IS ACTUALLY NECESSARY

LET US KNOW WHAT YOU GOT A GOING SO FAR

THE MEDIC

I

***REALLY NEED TO KNOW***

EVERYTHING!

ENGINE SIZE?

WHAT CARB DO YOU HAVE?

WHAT SYSTEMS YOU HAVE (LIKE POWER BRAKES???) AND THE REST OF 'EM TOO

LAST TUNE UP---EXACTLY WHAT WAS DONE---WHAT PARTS HAVE BEEN REPLACED THEN, AND SINCE

WHAT MODIFICATIONS HAVE BEEN DONE (MAINLY ENGINE/ IGNITION/ FUEL SYSTEMS?????

SEND ME SOME GOOD PICS DIFFERENT ANGLES WELL LIT FROM UNDER THE HOOD

TELL ME EXACTLY WHAT HAPPENS WITH YOUR JEEP---BEGINNING WITH HOW DOES IT RUN AND PERFORM NORMALLY?.....WHAT HAPPENS WHEN IT "GLITCHES".....DETAIL

I WILL HELP ALL I CAN......RIGHT NOW I'M IN YOUR GARAGE AND THE LIGHTS ARE OFF, I CAN HEAR IT SPUTTER!!!

I HAVE MANY PICS---I "LINK" TO OTHER POSTS (TO SAVE TIME AND NOT HAVE TO RE-WRITE STUFF I ALREADY HAVE) AND I TRY TO "FOCUS" ON YOUR PROBLEM

I NEED EVEN MORE INFO

DO YOU KNOW YOUR WAY AROUND UNDER THE HOOD OF A CJ?

DO YOU HAVE BASIC MECHANICS TOOLS?

DO YOU HAVE A DIGITAL VOLTMETER?

RESULTS OF YOU LAST INSPECTION AND EMISSIONS TEST?

DO YOU HAVE TUNE UP TOOLS SUCH AS A DWELL/TACH METER AND A TIMING LIGHT

MOST-US OF ALL........DO YOU HAVE A REPAIR MANUAL TO GO BY?....MY 1ST LINK TO YOU!

https://www.2carpros.com/questions/2007-ford-taurus-tune-up

I REALLY HUNT AND PECK SLOWLY, I WRITE "NOVELS" TO YOU AND "TEACH YOU" IF NEED-BE. I SEARCH FOR THINGS TO AID YOU, I TAKE AND POST PICS......I REALLY TRY TO DO ALL I CAN, I WILL RESPOND TO YOU AS LONG AS YOU KEEP RESPONDING TO ME

I WOULD REALLY APPRECIATE IT IF YOU WOULD REVIEW BACK THRU THIS AND ANSWER MY QUESTIONS...ALL OF THEM.....EVEN IF YOU LIST THE STUFF IN "NUMERICAL ORDER" IN A WAY I CAN UNDERSTAND IT........YOU ARE ALLOWED TO WRITE A NOVEL BACK TO ME!

IT'S SORTA NOT FAIR...I WRITE A NOVEL...YA'LL WRITE 2 LINES....I HAVE TO PRY FOR INFO!

THIS DOES NOT APPLY JUST TO YOUTHAT'S SORTA THE NORM AROUND HERE, WE DON'T GET ENOUGH INFO, IT FRUSTRATES BOTH YOUR END AND MY END, NOT TO MENTION THE DELAY IN GETTING YOU FIXED .......ESPECIALLY WHEN I/ WE NEED TEST RESULTS ASAP IN ORDER TO GET AN ATTACK PLAN STARTED

YOUR TURN....MAYBE WE CAN GET STUFF ROLLIN' NOW!

PICS WOULD BE SO HELPFUL TO ME....THE MORE THE MERRIER

THE MEDIC

LET'S NOT DROP THE TANK YET

I GUESS IT'S STILL INNA COMMA?

0) KEY ON--WHAT IS YOUR VOLTAGE AT THE POSITIVE SIDE OF THE COIL. SEE LAST PIC

1) LETS MAKE SURE WE HAVE THE CORRECT COIL. SEE PIC 1

2) RESULTS FROM STARTER FLUID SQUIRT IN CARB?

3) REMOVE #1 PLUG WIRE AT THE PLUG--WEDGE A NAIL OR PAPER CLIP INSIDE THE BOOT BETWEEN THE METAL RING AND THE RUBBER. HOLD THE PAPER CLIP 1/4 INCH AWAY FROM SOMETHING BARE METAL ON THE ENGINE---HAVE YOU PAL CRANK IT OVER 5-10 REVOLUTIONS. DO YOU HAVE A NICE BLUE "POPPING" SPARK JUMPING TO THE GROUND?

IF YOU HAVE NO SPARK---REMOVE THE IGNITION MODULE AND HAVE IT TESTED AS IN MY VERY 1ST ANSWER TO YOU (ABOVE)

4) REMOVE DISTRIBUTOR CAP---CRANK ENGINE OVER. DOES THE ROTOR BUTTON TURN?

5) IS YOUR FUEL SYSTEM SET UP LIKE THIS W/ A FILTER "1 IN"---"1 OUT" TO CARB (CENTER PORT)---"1 OUT" TO FUEL TANK RETURN LINE? DISREGARD MY REGULATOR AND MINI FUEL PRESSURE GAUGE. SEE 2ND PIC

6) LOOK AT YOUR VACUUM LINES. ARE THEY ALL CONNECTED AND SERVICEABLE? IF THEY ARE A MESS. YOU ONLY NEED 2-4 VACUUM LINES TO RUN THE ENGINE, UNLESS YOU HAVE POWER BRAKES, THEN YOU HAVE ONE MORE!

7) I CAN SEND PICS OF HOW TO MINIMIZE THE VACUUM LINE MESS DOWN TO THE BARE NECESSITIES IF YOU WANT ME TO.

DO YOU HAVE THE CORRECT PCV VALVE. PIC 4 IS A 1979, MINE HAS A VACUUM CAP ON IT, NORMALLY THEY COME WITH A PLASTIC PLUG TO PLUG OFF THE PORT MY CAP IS ON, THIS WOULD ELIMINATE THE NEED FOR THE VACUUM CAP

8) CONTINUITY TEST FOR DISTRIBUTOR PICK UP----SEE PICS 4--8. DO WE HAVE BOTH GROUND AND PICK UP W/ GOOD CONTINUITY?

I HAD TO WORK LATE, AND AGAIN TOMORROW.I WILL RESPOND WHEN I GET IN

PIC WOULD BE SO NICE!
