Then the engine fuse may be blown it will be marked ECM I think, the fuel pump and injector circuits are two seperate systems, the fuel pump most likely has a stuck relay.

The relay is more than likely in the fuse box under your hood.
I would check that box first, then the inside one.
I think it's in the battery box, I know in the older models it was there, number 301.

Probably has a plugged catalytic converter from the misfire that was on cylinder #2, which was indicated by the code. If you wanted to confirm the plugged cat, you could remove the precat O2 sensor and drive it. It will be noisy, but if you get an increase in power, you know you have a restriction

Its under the hood drivers side on the upper firewall.
It's under your hood, in one of those boxes, and should be marked. Your pump won't cut in if it's fried either. Check to see if there is power at the pump. Maybe you just have a loose wire. You can always hope!
