Did you ever get this problem resolved? I am having the exact same issue with a 2001 and it is driving me crazy. Replaced coil, cmp and ckp; even went another step and replaced the PCM and had it reprogrammed at the dealer but to no avail.
Cranks but no start
Spark at #1 and #4 but no spark on #2 and #3
Crank signal to coil 1 which runs cyl 1 and 4, but no crank signal to coil 2 for cyl 2 and 3
Low compression but I think it is just washed down from over cranking at this point.
If you got this resolved I would love to hear what you did to resolve it.
Thanks in advance,
