"...I only have pressure when you 1st turn the key or when you crank it...Not with just the key on after the initial gush of fuel..."
That's the way it should work.
If you have good fuel pressure and good spark, then the Radio Suppression Relay is a VERY LIKELY cause of your problem. Try swapping the connections with the Aux Fan Relay, which is an identical relay and sits right next door to it on the front side of the coolant expansion bottle. If it starts, you found the problem.
Both of those relays should have their circuit connections resoldered. I've resoldered three of those relays in the last couple months on both my wife's 90 740 (preventative maintenance) and my mother-law's 89 740 (dead at the gas station). (No aux fan relay there on the 89, not sure where it is.) I found it was the same two pin connections on all three relays that showed the greatest amount of fracturing/crystalizing. You need a magnifying glass to see problem. At 50 years old you need a GOOD magnifying glass to see it.
BTW - In the case of the 89 that died at the gas station, she was cranking starter (no start) and when I smacked the relay with my screw driver handle, it fired up.
