Haha, sorry I couldn't get back to you quickly but today won't work out well because I have work this afternoon. I relieved the fuel pressure via the shrader valve on top of the fuel rail and very little came out when I pressed it down. I'm not sure how much pressure there was supposed to be there but it didn't seem like much. The car had been sitting for about 3.5-4 hours since I had last ran it.

Sure will be. I did replace the fuel pressure regulator. It was a pain getting to the lower mounting bolt. But anyways, I had let the car sit for three hours before I started it up. It started great. I'd say it cranked for a second at most. I'll report back how it starts up after a little more than 4 hours tonight after I get back from work.

Sounds like you got the fuel pressure problem solved

It fired right up after about four hours of sitting last night. However, this morning it took the same 5 seconds of cranking before firing up after sitting about 11 hours. I'm out of ideas right now.

Sorry for the late response. I don't have anything to test the coils with but I figure I might as well change them. I'm also getting fairly poor gas mileage. I filled it up last night when it was a hair away from empty and I was at 240 miles since I last filled the tank. I know that should be quite a bit higher. In other news, I hit 64k on Sunday.

You can get a decent low-end digital multimeter for around $20. It really comes in handy for troubleshooting all sorts of things on a car, and in the house. I'd get one of those, and see what that tells you before throwing more parts at the car. Personal opinion...

Battery was close to being dead this morning for some reason so I'm charging it right now. This is a PITA. I'm not sure how I'll be able to get the coils off because it seems like the screws are extremely rusted and it almost feels like they could crumble at any moment.
