Thanks for the response.
The vehicle has had this issue over several hundred gallons of gas, purchased from several name brand stations, as after starting it runs fine and starts easily after the difficult initial instance, I am thinking gas quality isn't a problem.
I will check the fuel pressure this weekend. What is confusing me is that it starts fine, after the morning ritual. If the pump pressure was not sufficient, wouldn't it be an issue all the time?
Thanks again
