First i do not think your fuel pump is the problem,the pump shuts down after 10 to 20 seconds
and some people think the pump is bad. ,,these cars have two quirks ,#1 the Batt has to be great and less than 2 years old,
i say great,,, not good, you can have the same batt for years without a problem ...
. then one day the car want start, recharge batt still no start then install new batt ha ha car starts...
.#2 the rcm ,,,car will not start, replace the rcm relay control module car starts,,the RCM is the blood of this car.
most everyone on this forum has a spare RCM and a crank and cam sensor in the trunk.
If u have someone close to u that has a crossfire limited or srt6 they interchange, try to swap just to see if
your car starts good luck,,,,jim home of the worlds fastest crossfire
