Results of code 42 troubleshooting

I know this much now:
* engine timing is perfect
* spark looks good
* old spark plugs reeked of gasoline
* vane voltage 0.97 or so volts
* fpr appears ok, no liquid gasoline, very faint smell of gas
* engine-off fuel pressure 38 psi

Engine will absolutely not start. It tries, sputters, coughs. Does seem flooded.

Am I down to the engine control computer? Should I replace fpr anyway? Anything else? Recommended computer?

Thanks so much,

Did you check for dislodged/torn hoses between the VAM and throttle body? Will it start with the VAM unplugged?

Please tell me where the VAM would be unplugged
Please tell me which hoses go between the VAM and throttle body
Any hoses I can find are in excellent condition.
I'm beginning to think I don't know what the VAM really is and where it is. It is directly connected to the throttle body, right? or no? I have never seen a picture of a labeled VAM on this website.
When I manually move the throttle full open to full closed, I hear loose, sloppy rattling on the passenger side of the fire wall.
Comments, directions?
Thanks,

OK, I found the VAM. Please disregard the previous message.

Have you tried starting it with the gas pedal about 1/4 way to the floor?

Have you checked for injector pulse on all 4 injectors using a NOID light?

As noted above, ECT voltage would be a good thing to know.

Have you checked TPS volts to be sure it is a little under 1.0 V at closed throttle and increases smoothly to 4.5V or so at WOT?

I am still thinking you have a bad vacuum leak somewhere that you havent found yet.
