2000 xterra won't start

[ussoccer9]

me and my friend decided to take on the terrible task of replaceing my knock sensor, which it had thrown a code saying it was bad. we took off the intake manifold, changed the sensor, and put everything back together the way we took it off.

now that its back together, it won't start. it fired up the first time, idled rough for a few seconds, then died. we tried again, and it would turn over but it wouldn't fire.

we took my battery out (turns out it was shot) and put a good battery in, and it won't even turn over now. we don't remember removing any ground wires except for the ones on the wiring harness, but does anyone know of any grounds behind the intake manifold that we may have removed and forgotten about?

we're stumped any help would be appreciated!

Check the fuse block on the passenger side wheel well just behind the battery. There's a couple are high amp (40+amps) fuses that can blow and cause the problem you describe.

i checked them out before, but i'll try them again with a test light, i may have missed something.

thanks!
