Let us know if the crank angle sensor is your issue. The crank sensor is a common issue with these motors because it's not only in plain view but it's uncovered and in a really hot area. That and magnets and heat don't work well with each other.

 

How did things work out? Did you change out the sensor and if so did it work, my venge is doing the same exact thing just trying to fix the prob.

 

also try cleaning injector if the cps does not work my had a prob like yours fuel filter had hole thru it causing injectors to clug[sm=gears.gif][sm=nxsmile.gif]
