    Hard starts like that I generally start with the fuel system, too. Standard 1st test for the fuel system is to put a fuel pressure gauge on it and see what the fuel pressure is.

    Most common problem for this is the fuel pressure regulator. After driving, remove the rubber vacuum hose off of the regulator, if any fuel drips out of it, you need a new regulator.
