Until relatively recently Vicki would fire up as soon as I turned the key. The started would barely turn over once and the engine would fire without a problem. Lately, the engine will turn over a few times before it will catch and start. When it starts, it starts and runs strong. No slowly coming up to speed or sputtering.

I've noticed that if I turn the key on and let it sit for a second or two the engine will start up on the first crank like it used to. It's almost like the fuel system has to pressure up because if I turn it off and try to start it again, it starts right up again. If I let is sit for a while (like over night, or while I'm at work) it will take a few cranks for the engine to catch, or if I do the key on/wait thing it'll start right up as ususal.

I really haven't done any diagnostics on it, but I wanted to see if this has happened to anyone else. I changed both the fuel filter and fuel pressure regulator about 50k miles ago. Is it time to do a filter/regulator replacement again?
