Did this work for you? Going through the exact same thing myself with an '02- just replaced the pump, ran great for about 4 days, now it hit or miss most mornings and never fails once it starts up. Relay is good, about to pull the PCM and have it checked out; but don't really want to do that if I don't have to.

Did not change the switch. I found a blown fuse for the power to read codes. Replaced the fuse, read codes and repaired what was wrong. It is much better now, but astill acts up on occasion.
