unhook each injector and rig up a little light bulb with socket and wire leads.  I have a tiny bulb with the socket and wire leads hanging on my tool wall to do "blink tests"  Just stuff the pos and neg wire up in each spot on the injector plug.  Turn the key on and crank.  The light bulb will blink each time the eec is programmed to supply and remove the ground.

to make your pump run full time in order to check the fuel presure,,,, find the eec test connector and ground the tan / light green wire.  turn the key on and you should hear the fuel pump running.
try to start the car with the fuel pump relay ground wiire (tan/light green) up at the eec connected to a nearby ground.

also, check the tps for less than a volt with the key on only at the green wire.  now manually move the trottle linkage by hand slowly and watch your voltage increase smoothly up to about 4.5vdc.  If you have an intermittant open in the TPS, you wont start.  The tps is just a variable resistor.

i dont know if this has been mentioned yet but check your grounds for the oxygen sensors AND the ground for the oxygen sensor wiring harness itself, same with the fuel injector harness.
 
 
ALL I KNOW is that this winter when i did my HO conversion at some point the orange "oxygen sensor harness ground" got cut or something and became a two inch long wire with no bare wire hanging out at the end of the sheathing. I messed with so much , testing injector voltages and all that and JUST HAPPENED to notice that when digging through all the wires. grounded it out and the thing ran like nothing ever happened. I would love to know WHY that was necessary, as you run into all kinds of people who are "runnin' 'er without the oh-two's in" but that somehow prevented my car's injectors from firing.
 
Who knows maybe this was useless but we all know how you feel, so it follows that I too do right now, I remember how VERY angry and frustrated I was, and even more when I found out wha was wrong, so Im just puttin' it there just in case.
 
That last video is nice though, even if thats just for a few seconds on stuff you dumped in :hick:
 
Good luck!
