like I said, it's close to the 1/2 circle thingy that the throttle cable is on... one of the arms on it will hit a switch when it's WOT!

it's the TAS Throttle angle sensor on the diagram you posted... it's a standard potentiometer.... 3 wires out green/white yellow/white should have the total resistance measured across them... then from green white to red/blue should be 1 resistance and from red/blue to yellow/white should be a another resistance ./.. add the last 2 resistance measurements together you should get the same resistance as measurement one.
do this for various throttle angles

do you have the FSM, Haynes or Chilton? There is a section that describes what the ECU looks for under starting conditions. It's either in the fuel injection section at the beginning or in the driveability and emissions section at the beginning. It'll describe what the ECU looks for in order to start. Cuz it may be looking for a crank signal from the crank position sensor in the distributor too.... read up on it for now. I'm going to the gym... be back tomorrow

so you found the problem
as for the TPS, you can do it unplugged and measure the resistance.

you should still get spark with a shot CAS...
however since the ECU doesn't now where the engine is at it doesn't know which valve is open to spray fuel into with might prevent the fuel from being sprayed at all.....

not exactly sure (since that picture you posted doesn't have a high enough resolution but it looks like the CAS is another inductor sensor (which makes sense for a magnetic pickup) anyways again check the inductance not the resistance.

I'd think so since the ECU needs to know when the intake valve is open so that it shoots the fuel at the right time ...
if you did the test as outlined in the haynes then thats cool.... best way to do it

The CPS tells the ECU that the engine is turning over and trying to start. Or similar... I'm not 100% on how it works on your car. For example, on my Saturn, the CPS tells the ECU to start the ignition coil firing (cuz I have a distributorless ignition). So double check what it is for your car specifically.

guess the CPS tells your ECU when to fire the injectors.

everything is hard to do when you are unwilling to bust out the tools and DO IT DO IT
NICE WORK!!

bb you will enjoy this
did a compression test....
Cylinder #1 - 110
Cylinder #2 - 90
Cylinder #3 - 90
Cylinder #4 - 50
NOW THATS A PROBLEM!!
BHG or valve not sealing...either way red90dx and I are doing a head swap next week.
