Truck will start sometimes and won’t start others. Replaced cam and crank sensors. Replaced battery and spark plugs. I’ve replace the cam sensor 3 times already and have checked the wiring it seems fine I got voltage. I’m super lost and can’t figure this out. I’ve read other forums and still no help. I tried replace the pcm as well.

 

That p0430 is related to catalytic converters I believe , perhaps its getting clogged up,,I would research some more on that code ,,might be wiring to 02 sensor , usually bank 2,,but the engine not starting might be clogged cat,,but maybe someone else will chime in with more advice

 

My bad wrong code p0340 is what I have

 

One possibility is its in the timing chain, something could be worn throwing off how the sensor is reading it

 

I don’t think so I had the chain and tensioner done 2 years ago about 5000 miles.

 

You may be right but that's about the only other thing other than bad wiring to the plug on cam sensor , even 2 years nothing is a guarantee

 

put a timing light on it when it is running

 

Maybe pull the sensor and see if there is oil or build up on the area its suppose to read ?
