Check your fuel pressure.

Bustedback

This is the first place to start before you shotgun parts at it.

^^this^^ You may have stirred up some crap from the bottom of the tank and plugged the filter.

Aaron Walter

Check it from the rail right?

Bustedback

Yes, there's a test port on the rail.

jon-d

any parts list (preferably with links) for testing the port?

Bustedback

A fuel pressure tester that screws onto the test port.
