Raw Diesel Smell in cab and periodically dies...

Lately my truck has had a "miss"/"jerk" while going down the road... you can be in, or out of the throttle. and if your coming up to a stop, and it does this it will die.....I've replaces the ICP sensor, and notice now that it helped out on the "MISS" while driving down the road at normal RPM. But It will just die at the red lights or stop signs. it just completely shuts off... there is no spitting or sputtering. just like you cut off a light switch... only thing ive noticed more is a stronger "raw" fuel smell in the cab, coming though the air vents... I'm wondering if I may be sucking in air in the fuel throught a potential leak. I've read a lot about the orings in the fuel bowls. Looking for someones elses two cents on my situation.

Check for fuel leaks. Most likely the drain valve on the back of the fuel bowl.

CPS will not cause a raw fuel smell

Do you think the CPS might be the issue on making it Miss? I drive 80 miles 1 way to work and this morning i didn't have any issues... but one day it dies 3 times at one red light... but after that never missed a lick...Puzzels me.

CPS can cause a miss. But it will not cause a raw fuel smell.
