Ok here's the update:
Pin 21, engine cold, key to "on": 4.98 volts
Pin 21, engine warmed, key to "on" 0.000 volts
Pin 3b, key to "start": 9.40 volts
Now all these voltages were read while car was not running. So my pin 21 volts are a lil high on cold and nothing while warm? What's your thoughts?

With the reading your getting the ECU is choosing to use too little fuel on start up when it should be using more so you need to fix the poor connection to hopefully solve your problem. If the sensor was feeding the ECU a proper reading the engine would inject more fuel upon start up than it is currently getting.

You likely have a bad connection to the Water Thermosensor, which is located behind the water pump, and below the alternator. It has a plug which looks like the plug on the injectors, and BAC valve. The G/W wire is one of the two wires at the sensor, and the second wire is a ground. Either the plug is loose to the sensor or one of the two wires is pulled back in the plug and not making proper contact w/the sensor itself.

Yes this all seems to make sense. The water thermo sensor is the top green plug, that's the one to the ecu correct? I've had the clip on and off before but I guess I should tear it all down again and remove the electric tape that whoever did the swap to ensure a proper connection. I also noticed a high idle on the car. It's at about 1,500 all the time so I can't even check the timing correctly... Any thoughts in that? Thanx again for all the help I'll get cracking on it tomorrow again

High could be cause the Fast Idle Cam on the rear of the throttle body is non functional and causing the throttle plates to stay open too much or the throttle cable or cruise control cable are too tight. W/respect to the Fast Idle mechanism there is a metal rod that is supposed to stick out more and more as the engine warms up and it presses against an upside down screw. As the screw is pressed down the throttle plates close and lowers the idle. This item is closer to the passenger side on the rear of the throttle body.

Mess with what the BAC or the car? I'm not gonna mess with anything I don't have to lol. But I got learn somehow. So next on the list to do is get the water thermo sensor wiring checked at the harness and look at the idle issue. But what doesn't make sense to me is why would the voltages be to high? If there was a bad connection wouldn't it read less voltage?

Just fix the thing. And has the thought crossed your mind to look through the FSM and educate yourself? I mean it would not suprise me if you asked me what a door handle is. Do you think I get paid for helping people. Don't you think you're taking liberties by asking questions you could obviously find out on your own?

Ok so I found that the clip going to the water thermo sensor was junk and makin the g/w wire back out of the clip. I removed the clip hardwired the wires to the water thermo sensor and nothing changed?!?! Voltages are the same. And car will not start on its own without starting fluid... Any thoughts anyone?
