Ok, I went through the trouble diagnostics EC-740-EC749

I checked all of the pins I could with the engine not running [engine running required in some tests.

Here are the results. I had a problem with the throttle position sensors, AND THE BRAKE SWITCH.

Ok here are the results.
pin [or P] 3 =12v
P4=.672v
P5=3.5V
P6=12V
P25=12V

P32=4.08V
P47=5V
P48=5V
P49=5V
P50=.36V, AND .36V NO CHANGE WHEN PEDAL PRESSED ***** NOT READING CORRECT
P54=3.77V

P68=4.7V
P69=4.3V, AND 4.3V NO CHANGE***********************NOT READING CORRECT
P78=0V
P85=9.3V
P86=2.3V
P90=5.07

P91=5.07V
P94=2.7V, AND 3.8V
P98=P2.29V
P99=4.05V, 0V, 1V, 3.04V AND 2.02V
P101=0V, AND 0V ************************************ NOT READING CORRECT

P102=0V, AND 10.9V
P104=12V, AND .89V
P106=.76V, AND 4.57V
P108= 0V, AND 12V
P109= 0V, AND 12V

P111-.80V, AND 12V
P113=1V, AND 12V
P117=12V
P119/P120=12V
P121=12V

NOTE: P101 didn't read correctly when the brake pedal was depressed which was supposed to be 11-14v. [could this be tied to the U1000 ABS, CAN line malfunction, I'm reading with my scanner?]
