I took my 2007 challenger 180se out yesterday and while driving I noticed the low fuel flashing so I headed to the ramp. While driving it appeared to have run out of gas. The gauge still showed I had just under 1/4 tank. While trying to start it floating level in the water I got a 344 code ( no cam sensor ) I put 5 gallons of gas in it and it still won't start but I do not get any codes anymore either ?? Thanks for any help.
