These engines do not need that to start up.
Hard start even with new injectors, injection pump and glow plugs...help

It can really help especially when hot, it drops the housing pressure and helps the plungers move further out since transfer pressure is null in a worn out pump at really low rpms (cranking speed)

Lets see:
1. Varying pressure at the IP inlet affects timing. It really does. The ford mechanical pump, for me, was pushing 3-4 PSI from the outlet of the filter, from idle to WOT at max RPM. Excellent stability.
2. Cold advance helps, especially with a relatively retarded timing setup. Some pumps/timing setups don't need it, some do, especially when you are dealing with worn equipment.

Have you checked your injection pump timing? Sounds like it may be slightly retarded to me at first blush...
Sometimes it helps if you press the accelerator pedal 1/4 depression while cranking after glow plug cycle and wait to start lamp extinguishes. Also ensure that your glow plugs are actually within resistance parameters and receiving proper voltage and amperage during initial start cycle. Do not use ether try a new can of wd40 instead it has more lubricity to avoid hot starts or premature wear on rings and turbo cartridge.

Im in newberg with a timing meter.
Who do I text to find that out?
I have the same issue, I have replaced everything on this engine and still it wont start without either. But only difference is , once mine starts, I can shut it down and it will fire back up on its own. When it sits overnight, it need a little puff to start.

You might try rigging up a manual GP override button; hold it on for like 15 seconds and then crank.
From past experience, really low compression motors won't pop on ether, but will fire with enough glow time.
Timing being off, though, I've had that be startable with ether.

Got a good deal on a '93 F250 IDI Turbo. New batteries, glow plugs(not Motorcraft), electric fuel pump, return line caps/o-rings, installed manual button to bypass glow plug controller...... and it still didn't want to start! Guess what...solenoid for glow plug controller was clicking but not making contact internally. Discovered this when I jumpered across the controller. New solenoid installed for ~ $12, and she starts all the time, everytime.
