You need to verify fuel pressure at the fuel rail. When you turn the key on, the fuel pump should run for a few seconds. You can cycle the key on/off a few times to "prime" the fuel system with pressure. Remove the schrader valve cap on the fuel rail and hook up a fuel pump test gauge to verify...
I cannot locate the part number(s) but the '96 EATC unit is preferred.
All '93-'96 EATC units will interchange. The '97-'98 EATC units are not compatible with the '93-'96 models.
'94-'94 have the weak front buttons while the '95 was similar but improved. The '96 used more solid oval buttons.
To the best of my knowledge, the "California" moniker is simply a dealer dress-up, much like the "Presidential" and others.

"Pearl White" 96?
What's the exterior color code?
"WK" Opal Opalescent
or
"WT" Performance White
If "WK", I may be interested in the mirrors and who knows what else.
You can probe the wires to the cam sensor and check for AC voltage when running. Should be 0.5 vac to 1.0 vac. An analog meter is best as the voltage output is not static and will be sporadic on a digital volt meter but should still show a fluctuating voltage. Checking while cranking may or may...
A more common PCM repair is COP ignition or fuel injector drivers going bad.
There used to be a PCM repair facility on the web but I saw a while back someone said they had went out of business.
FWIW, I keep a spare around just in case.
Try replacing the PS fluid. It may take 2-3 or more times to get rid of the old fluid completely.
As for the coolant cap, they are cheap enough to replace as well when you flush the coolant system and R&R the thermostat.
No, not unless you add one.
I have an old "spyder valve" assembly on my '93 which has a schrader valve. I actually used it once with shop air to find a line leak.
