Circuit Description
Moving the ignition switch to the START position sends a 12 V signal to the PCM Ignition Crank Sense. The PCM verifies that the transmission is in the PARK or NEUTRAL position. The PCM then grounds the control circuit of the START relay. When the START relay is energized it allows battery positive voltage to the starter solenoid S terminal.
Turn the ignition switch to the START position.

Under dash driver side look behind the upper arm of clutch pedal and you should see a green and black wire coming from the button (switch) assembly on the firewall. The wires go up above the clutch pedal. About in the middle of under dash on the left side you should see a white connector these wires run to. Disconnect. I just had the problem and not only starts now but not stalling like it was but it's only been one day but tested it pretty good.
