i bought my crossfire on ebay as running condition i got it and didrent even start,so i tried the rcm dyi fix and nothing so i got an aftermarket crankshaft sensor and it started i was happy but then once i pass 3k rpm's the engine dies and it always starts right after it dies and i get that p0335 engine light right away.can the problem be that i need the oem sensor?

 

Search the SRT Forum on P0335, there are any number of helpful hints, from a bent/damaged Flex Plate, damaged replacement CPS, including a wrong CPS purchased at Autozone.

Here's one link of the many that returns on a Search:
