Seems like the wait to start light is on 10-15 seconds first time, then key on/off/on several times, wait to start light on shorter time, then finally after a 4-5 cycles of same it'll fire. Today, similar program only would not start, 30 degrees overnight. Finally pushed accellerator to floor and release while ignition key on, then cranked and start, rev'd briefly(2-3seconds), then released to low idle 600RPM, never higher. That's why I have the question about the high idle solenoid in relation to the glow plug relay.
