Victim -- my 'new' 89 245.

I pulled it into the alley behind my house to do some minor things in the drizzle, and decided to pull it tighter to my fence. It wouldn't restart. That was 2 hours ago. In that time, I have done the following:

-- reflowed the solder on the fuel pump relay. Visually verified that both relay circuits click when fed with current, and they release when the ignition switch is off.

-- verified that spark is arriving at #1 sparkplug.

-- replaced distributor cap and rotor.

-- replaced 25 amp fuse.

-- pulled 1-1-1 code on EZ diagnostic system (i.e., 'no faults in system').

Checking with the 700/900 FAQ, I've sensed that a warm no-start isn't uncommon with an aging crank position sensor. Does this work much like a Hall sensor in the LH 2.X system -- if there's failure, there's no fuel, no spark? If the crank position sensor is failing, why would I have spark? I'm new at the EZ system...

Other possible culprits -- power stage/radio suppression relay?

At this point, I'm at a loss of where to procede next other than replacing position sensor and power stage 'just because'. I intend to do that anyway with this car, but is there a way that I could diagnose their failure? And why is the EZ system giving me a 1-1-1 if they're on their way out?

Any wisdom is greatly appreciated!
