Question type: Maintenance & Repair

Chrysler 300m 81,000. The car ran prior to me changing the senor, it took a while to
turn over, i would have to turn the key and hold it for a few seconds then it would

I checked code which was a po344 so I changed cam sensor with aftermarket sensor.
I started the car and let it run for a few seconds and then I cut it off, I did this twice.

I then torqued the upper intake bolts to spec and put the air box back on then I tried to
start the car but would not start. it cranks but will not turn over. I put the old sensor
back in (which was missing the paper gasket) but it still will not start with the old
sensor either.

I believe the cam controls fuel? I wasn't sure so I didn't want to flood the engine with
constant cranking..
