97 Yukon Hard to start

Some weird state law thing that I still can't find anything about. I have a scanning system just not a fuel pressure tester.

THX for the help earlier today, really appreciate it. Hopefully it goes past 2 days without a problem.

Just an FYI for us OBS owners. There have been multiple updates to the crank sensor from GM. See you local dealer for the latest one, it may cure hard starts and long cranks, sure did on my dads truck.
