i have a 05 sxt. i was on my way to work and the timing belt broke after 5000 miles of changing the last one. anyways my husband did a complete vavle job and everything replaced the belt and water pump. and now we have no start. he checked a bunch of things and found out we have no 5v reference signal to the cam sensor. changed cam and crank signal from dealer and still nothing. we also changed the computer. and still nothing. any help would GREATLY be apprectiated. thank you

edit-we also have 3 codes = p0340, p0335, and something about the BARO reading out of range. dont remember excatly what number it was
