I'm trying to find out if there is a difference between a 1999 and a 2000 Chrysler LHS 3.5 engine. I swap the engine from a 2000 Chrysler LHS with an engine from a 1999 Chrysler 300M. When i tried starting the engine from the 1999 Chrysler 300M it wouldn't start. Took it to a shop and they put it on a machine and it said something about the cam position tone wheel error. Are the flexplate and the tone wheel the same on those two vehicles or are they different? Any input would be greatly appreciated.
