Like I said on my frist post. I can turn the key, it will turn over and over ect, sound like it will start then nothing. Then other times it will start will alot of pedal pushing, then the hole Truck shakes.

 

Try the coil, like has been suggested.

 

Ive replaced that A week ago from napa

 

Unscrew the precat o2 sensor from the pipe and see what it does.

 

I'm starting to wonder if the crank sensor is out or nearly out. I would say get it started & get the codes read.

 

Have you verified that you're getting spark, fuel, and compression in all cylinders?

I'd start from there. You can replace all the sensors from china to the moon but if you don't have those three things you ain't ever gonna get it to start

 

A failing crank sensor can cause this, but i would say get the codes read asap.
