I was on my way to work and my truck sputtered and shut off. The check engine light came on about a month ago. Trouble codes P0340, p0344 suggested a camshaft sensor issue. I replace both Camshaft and crankshaft sensor and still will not crank. It turns over but will not start.

 

Welcome to the site. I will check the codes tomorrow at work. In the mean time maybe someone else can help out

 

PO340 is No cam referance signal from the CMP sensor at the PCM.

 

your thread title says "help" but does not describe a problem or anything in reference to your thread.

Maybe if you included this in your title you would get more help.

 

Does this mean that cam sensor is bad, I replaced both cam & crank sensors. Still having a no-crank problem.

 

Need some info on your truck, what engine are you running and have you done any previous work to it that might help us out a bit.

 

I have a 4.7 magnum I have had the truck for just over a year. I had the timing chain replaced about 8months ago. That has been the only work that has been done to th truck so far. As I said I replaced the crank and Cam sensor last week, with no luck.
