F350 died going down the road!! HELP!!

[irtsniper]

My 97 F350 died going down the road. it was like it almost ran out of fuel..all it will do is turn over and over. no blown fuses...new fuel pump 1 week ago put in due to leaking fuel from top of motor and drain valve was replaced too...we put the a crank sensor in it. still just turns over!!! any ideas??? ran like a top prior!!!! 159000 miles on motor!!thanks.......codes are po344 and po340.........these came from a superchip programmer!!!

change your fuel filter lately??
clean your injectors lately??

Does your tach move when you try to start? The CPS could be bad right out of the box.

[irtsniper]

yes, tach moves. fuel filter changesd1 month ago...was running lucas on a reg basis and was lucas in the tank!!

[jfines@cox.net]

OK next question, do you have access to a scanner that can check for codes?

Then fuel wise, is your filter bowel full? pull off the lid and see if it pumps up while cranking.

But a code could narrow it down fast.

sounds like a cam sensor problem

agre with puling the codes before going any further , run a fuel pressure test and make sure oil is full and in good shape, and by all means dont buy any parts on a whim or a guess, diag first

Ill have codes by the end of the day..we pulled them but i cant remember what they were!!

[irtsniper]

codes are po344 and po340......checked all fluids all are fine!!! none low

[SCUFFY828]
