Wont start when cold

I have recently been having trouble starting my truck which has 350000 miles on it when the outside air temp is in low 40s and colder. If I plug the block heater in for about an hour it will start. I recently had a new injector pump installed and I can also hear the lift pump run for several seconds after I bump the starter. Thinking it could be a problem with the grid heater but I also believe the truck should start in mild temp without the grid heater. Any suggestions?

You got 350,000 on them....that's a good run!! Not fun dropping $2000+ but at those miles, it's a safe bet it's the injectors.

Whatever you do, do NOT buy remanufactured injectors....buy new. I sourced mine locally. Good luck!

I put 50 hp DDP inkectors in my 05 and are happy with them. No problem adding them to a stock truck.
