its auto done that let me tell you what they done they took the dash out to replace the blower motor it acts like a neutral safety thing
does it have anti thief to the left on the door their is a plug with a key that's not lit up but I can turn the key on and start the car from the relay under the hood
OK, your going to need an ohm meter to check continuity of the wires. I believe you have an open circuit or a connector disconnected if this problem happened right after the dash was removed. Are you familiar with using an ohm meter? or 12 volt test light? The PINK wire runs from the ign. switch to the ECM (Engine Control Module) The ECM then GROUNDS the starter relay to provide power to the starter motor. You need to check and see if you have power at the ECM pin 87 (PINK wire) When key is in START position. If that checks good, then, You need to check pin 27 (BLACK/BLUE wire) From ECM to starter relay. One of those circuits is open in my opnion. Both of those should read less than 5 ohms indicating a good wire. Here is the schematic.
yes the pink is hot and the black and blue when grounded will start the car under the hood
