Why would the car run fine at idol in park and then stop like the key was turned off?

It will not restart till it wants to, and there's no spark. Afew hours later it will start and run perfect !

Check fuel pressure. Check the ignition relay when the problem is occurring. Make sure the coil is receiving power. Make sure the ground side of the coil is being interrupted. Use a test light for this. It should flash. Check internal and external coil resistance when the problem is occurring.

REMOVE YOUR IGNITION MODULE (ON EITHER SIDE OF THE CONNECTORS GRASP THE WIRES AND PULL HARD (DIGGING W/ A SCREWDRIVER IS SORTA FRUITLESS) IF YOU PULL EVENLY ON THE BUNDLE OF WIRES, IT WILL COME APART AND YOU WON'T BREAK THE LOCKING TABS

THIS SHOULD BE WHAT YOURS LOOKS LIKE, IF I INSTALLED THE CORRECT VEHICLE INFO IN THIS LINK

http://shop.advanceautoparts.com/webapp/wcs/stores/servlet/product_Ignition-Control-Module-BWD_5240522-P_194_R%7CGRPTUNEAMS_____#

OFF TO A POPULAR AUTO PARTS STORE, YOU GO....THEY USUALLY WILL TEST THESE FOR FREE

LETS WATCH AND SEE IF THEY HOOK UP RIGHT (IF YOU KINDA CAN READ THE CHART THEY ARE READING)

THEN HAVE THEM TEST IT 5-8 TIMES (THIS WILL WARM IT UP) SHOULD IT FAIL THE LAST FEW TESTS.....ANY THING LESS IS LAZINESS....AND YOU MIGHT SUFFER...NOT THEM!

WHAT IF IT FAILS?.............YES, REPLACE IT!

AS YOU PUT YOU HAND ON THEIR DOOR HANDLE TO LEAVE, WITH YOUR NEW ONE............

TURN YOUR BUTT RIGHT AROUND, GO BACK TO THE COUNTER, AND HAVE THEM TEST "THEIR" NEW ONE 5-8 TIMES.

WHY????

THERE'S NOTHING LIKE TEARING YOUR ENTIRE JEEP CJ 5 DOWN (EVEN THE WIRING) FOR 2 DAYS, TEARING YOUR HAIR OUT!.........BECAUSE IT, >>>>WILL NOT START!!!<<<<, THEN YOU TAKE THE BRAND NEW>>>UNTESTED MODULE,>>>BACK TO THE STORE, ONLY TO FIND OUT, >>>IT TOO!!!<<
SEE HOW MY PERSONAL---"BAD CHAPTERS"---MAY BENEFIT YOU, PROBABLY BETTER THAN THE OTHER FOLKS. LIKE MY 30 YEARS OF HARD KNOCKS DRIVING AND REPAIRING, OUT OF PURE NECESSITY!!! I'M PURELY DIY, MY JEEPS HAVE NOT BEEN TO A "PAY GARAGE" SINCE '87, WHEN I WAS DEPLOYED AND THE WIFEY HAD A MINOR PROBLEM!

I TRY TO CRAWL UNDER THE HOOD WITH YOU!

...YOU WANT ME TO HOLD THAT LIGHT, WHILE YOU SNATCH THE IGNITION MODULE LOOSE?

ARE YOU ABLE TO FOLLOW MY COUNTRY-FIED TECHNICAL TURBULENCE?...IF NOT LET ME KNOW

RETURN WITH ANY OTHER THINGS YOU MAY HAVE MESSED WITH WITHOUT MY ASSISTANCE

IF IT'S NOT THE MODULE, WE WILL CONTINUE...ARE YOU VOLTMETER COMPETENT? DO YOU HAVE ONE?

WAITIN' ON YOU

I ANSWERED THIS AND ANOTHER QUESTION EARLIER--BOTH NEVER POSTED,--BUT NOW I'M GETTING NOTIFIED?????

LETS CHECK THAT IGNITION MODULE (MAINLY BECAUSE YOU SAID THERE IS NO SPARK AT TIMES)....AUTOZONE AND ADVANCE AUTO, BOTH TEST 'EM FOR FREE IN MY AREA!

LETS WATCH AND SEE IF THEY HOOK UP RIGHT (NORMALLY THEY EYEBALL A CHART.... TEST THE MODULE 5-8 TIMES (THIS WILL WARM IT UP) SHOULD IT FAIL THE LAST FEW........

YES, REPLACE IT!

AS YOU PUT YOU HAND ON THEIR DOOR HANDLE TO LEAVE, WITH YOUR NEW ONE............STOP!

DO AN ABOUT FACE, GO BACK TO THE COUNTER, AND HAVE THEM TEST "THEIR" NEW ONE 5-8 TIMES....REGARDLESS OF WHAT EXCUSE THEY PRESENT YOU WITH!

THEY ARE SUBJECTED TO A LOW RPM AND HIGH RPM TEST, AND OTHER STUFF ELECTRONICALLY I DO NOT UNDERSTAND.

THERE'S NOTHING LIKE TEARING YOUR ENTIRE JEEP DOWN (EVEN THE WIRING) FOR 2 DAYS.........BECAUSE IT, >>>>WILL NOT START!!!<<<<, THEN YOU BREAK DOWN AND TAKE THE BRAND NEW>>>UNTESTED MODULE,>>>BACK TO THE STORE, ONLY TO FIND OUT, >>>IT TOO!!!<<
SEE HOW MY PERSONAL---"BAD CHAPTERS"---MAY BENEFIT YOU?

I TRY TO CRAWL UNDER THE HOOD WITH YOU!.........YOU WANT ME TO HOLD THE LIGHT?!

THE BEST WAY TO UNHOOK THE MODULE, MAY SOUND LIKE YOU WOULD HURT THE WIRES. MY JEEP CJ 5 MANUAL SAYS GRASP THE WIRES ON EITHER SIDE OF THE CONNECTORS AND PULL THE WIRES HARD....THIS DOES WORK WELL, AND KEEPS YOU FROM DIGGING AT THE CONNECTOR WITH A SCREWDRIVER AND BREAKING OFF THE LOCKING TABS

HERE'S WHAT THE BEAST LOOKS LIKE...NOT REAL EXPENSIVE EITHER...I KEEP AN "EXTRA" IGNITION MODULE, COIL, AND A FUEL PUMP IN MY JEEP AT ALL TIMES, ALL ITEMS I HAVE HAD FAIL, IN THE WORST OF SITUATIONS!

WHEN IT RUNS--DOES IT SOUND GOOD, OR IS IT REALLY ROUGH?

LAST TIME IT HAD A MAJOR--ALL OUT TUNE-UP...TIMING, CARB ADJUST, ETC.???

PLEASE LET US KNOW IF YOU HAVE TINKERED OR ADJUSTED STUFF!

WAITIN' ON YOU
