Hard start

[Fptodd]

I’ve got a 2004 6.0 power stroke that has no injector clatter and it will start after the fuel pump stops running but it starts slow any help would be appreciated.

First, charge batteries individually and then load test them individually.

Got a pressure gauge on the hpop system? Those pumps get tired.

A good scan tool to read ALL the PIDs in the high pressure oil system, the FICM voltage PIDs, SYNC PIDs, and rpm (as well as retrieving ALL codes)!
