The '99 Burb cranks, smokes, no start

[Lightyear]

Hello everyone

After sitting for about four weeks since the last stranding episode I stared tinkering with the Burb. She'll crank at starting speed, build about 30 psi oil pressure, almost fire, but not start.
So far, have done the following:
2 new batteries
New Stanadyne gray PMD from Kennedy
Cleaned filter manager
Replaced and bled new GM filter
Checked flow at IP inlet, good fuel no bubbles
Glow seems good, I can watch the voltmeter cycle with the key at on
Attempted start with optical sensor disconnected
Cracked open injector lines 1, 2, 3, 5, 6, and 7...fuel at each of those cylinders. (Can't reach 4 and 8)
It ran until I parked at long term parking for about 8 days, then would crank but not start. It feels closer to starting now, it'll buck and catch for a few seconds but not run, it has gotten to around 500rpm while trying and coughing. Gray smoke at tailpipe.

Any suggestions?

Thanks!
