Hard Start Issue Semi-Resolved

Took my car to the dealership to check on the hard start issue. Sometimes the car starts fine, other times it takes a while to turn over. I changed the fuel pressure regulator and the problem persisted. Come to find out it is a check valve in the fuel pump that has gone bad. They quoted around $500 I beleive to install a new pump and some fuel lines; I'm gonna wait. Hope this helps some of you. -Paul
