Archived 2nd lift pump and hard starting is back

[GSecrest]

I have an 03 3500 two wheel drive with a 6 speed manual trans. I changed the lift pump this past march as per issue #60 everthing went great . This past sunday during a small trip the harding starting came back. It's like all the fuel drains out of the line. I replaced the pump today thinking bad pump it didn't help. I have no visable leaks. I cycled the switch several times and it doesn't pump up. It runs great ,when it starts. any help. The truck has 164000 miles on it.

Leaky injector??

Could be injectors and/or crossover tubes. The rail has to build enough pressure in order for the ECM to let the injectors to open. If this pressure is not met during cranking you have a slow start or as in my case a no start. There may other causes but this is a common one for slow starting.
