8.1 Stalling Problem

[dave022500hd]

I HAVE AN 02 2500HD WITH THE 8.1 AND ALLISON THATS STALLS AND WILL NOT START, BUT IT CRANKS. ITS HAPPENED SEVERAL TIMES STARTING IN JAN. 07 THROUGH MARCH, BUT ITS BEEN FINE UNTIL THE OTHER DAY. I INSTALLED A NEW BATTERY IN DEC 06. WHEN IT DIES I'VE HAD TO REMOVE THE KEY AND HIT THE LOCK AND UNLOCK BUTTONS ON THE FOB IN ORDER TO GET IT TO START. I SWAPPED KEYS IN FEB 07. THIS PAST TIME IT HAPPENED HITTING THE FOB BUTTONS DIDN'T WORK, I HAD TO CYCLE THE KEY AND I LEFT IT ON A MINUTE AND IT STARTED. I FOUND THAT 4 OF THE RELAYS IN THE ENGINE FUSE BOX WERE INSTALLED DIFFERENTLY THEN SHOWN ON THE COVER, ONE BEING THE FUEL PUMP RELAY. NOT SURE IF ANYONE OUT THERE HAS SEEN OR HEARD ANYTHING LIKE THIS. ANY HELP WOULD BE GREAT.

Actually myself and others have been through it, and have heard this at least 25 times (no exageration) on here and in every instance it was a faulty crankshaft sensor.

I put a new crankshaft sensor in my 02 and it fixed the problem. Anyone with a 2001 8.1L there is a recall out for the crankshaft sensor!!
