1998 Yukon cranking but not starting problem

My Yukon started having problems starting when I was out running errands. I would go in the Bank come out and it wouldn't start, then I'd have to wait a half hour and it would start up. I got a code that the the 7 cylinder was misfiring so we replaced all spark plugs. Now, I go out it just cranks over and over, and finally starts after about 8 tries.
Do you think it is the Fuel Filter, crankshaft position sensor, or the ignition control module? When I turn the ignition on I can hear the fuel pump.
Any suggestion would be appreciated.

Check fuel pressure, 60-65 psi is required.
