Odd 4K no start

[DK]

Spark plug wires, ignition coil, cap & rotor check out to Bentley specs. I
have verified that I get fuel into the cylinders by jumping the fuel pump
relay and lifting the CIS plate, I could see a little puddle in the
Cylinders. Verified compression, all good 125psi (at 7000ft). Did not burn
oil or coolant before.
I tried messing around with the distributor but still no luck. It seems like
it wants to catch, but nada. I think it actually backfired last nite when
cranking it.

Any other suggestions? I will try some starting fluid to rule out if it is a
fuel problem...
