Well, my fuel pressure regulator was changed out probably 35,000 miles ago. Same with my EGR. I replaced it, not cleaned it.
Now Mark, I think you are on to something, because I notice the same thing. If I put the key in and turn it but not start up, I wait until the beep, beep, beep, beep is over and then usually it fires right up. Meaning the fuel pump has activated and got the right amount of fuel pumped up front. I sometimes wonder if it could be a tired fuel pump. The start up issues may or may not be related to my fuel consumption woes, but who knows?
I suppose I could pull my FPR and see if the screen has any holes in it, but again, I changed it a couple summers ago. I'll have to look back in my log book and find out exactly how long ago it was. Same goes for my EGR.

How long since you changed the fuel filter? That helped mine light up quicker, & is the cheapest / easiest / & maybe least fun solution to try first...
