help me solve my spark problem. *PICS*

OK, here is what i have done.
changed plugs
tried a known good plug wire on #1
swapped fuel injectors
passed a compression test

what else can I do??

Am I right in thinking that the high spark line in #1 is a reult of the problem not the cause of it. I think if it was high resistance in a plug wire or groung it would be high but the cyls would be functioning normal. They are not, both cylinders never hit more than 350 or so degrees, all of the rest are at 700 or so.

Pics are on the site at the bottom.

no, but I changed everything but the block (not joking) at the same time as the wires. so that doesnt mean much. #6 was a wire. #1 is not, Im still confused on that one.
