Engine is hard to start when at or near op. temperature. The engine starts fine when cold. But, after it has been running and has come up to or near operating temperture, and it has set for more than 6 minutes, I have to try it 2 - 3 times before it will start.
Replaces the fuel filter, no help. Replaced the fuel pump relay, no help. Replaced the plugs and this helped for a while. It seems to getting worse.

Our 2002 Park Ave is doing this too. We have 115,000 miles on it. Changed the wires and plugs, didn't help. Hope someone has a clue. There are no codes, fuel pump has lots of pressure. Thanks!
