Are the EGR solenoids crucial?

I removed the EGR solenoids during an EGR delete, and it seems that might’ve screwed me. I no longer hear the click of the glow plug timer. When I crank the engine, I hear clicking like mad from the glow plug relay, but I don’t think there’s any current flowing to the busbar.
I didn’t think the EGR and glow system were linked until I saw this diagram:

I’m not sure where the Glow & EGR control unit is that’s mentioned here (behind the battery?) but perhaps it needs output from the EGR solenoids to run the plugs?. Unfortunately this was part of a much bigger repair so I threw the solenoids in the garbage weeks ago.
Let me know if any of this rings a bell for anyone.
 
The control box we call the "glow plug controller" actually also controls the EGR valves. But that is a separate function/circuit and it is not interrelated.
 
Ok, thanks @Jgrant0553 @sk66 . Guess I'll test all the relays and controllers again. Might be coming to you for that manual bypass soon @sk66 if all else fails. My battery drained fully so perhaps that's a factor in why I can't start the van. Might have to disconnect it and get a full charge.
 
If you are getting rapid clicking from a relay and it won't turn over; that's probably the starter relay chattering due to low battery (the starter relay is back there next to the GP relays).

Okay, sweet. That checks out. The relays don't click when the key is "ON" but when I try to turn it over it sounds like the starter relay is going crazy. I'll record a video and then get this battery up to the autoshop.
