New fass pump and now twice my truck has not wanted to start, it will crank but acts like no fuel at all then it catches and runs fine. Is this symptoms of a bad cp3 pump or something else. I did the lift pump cause it died on me while driving.

 

Could be a small leak in the line causing it not to start right away. Do you smell any diesel?

 

Nope, no leaks no smell of fuel, everything looks good.

 

Do you have a fuel pressure guage to make sure you are getting adequate pressure? Try changing the fuel filter too.
