turn key in ignition to run, but don't start. take long screwdriver or socket extension and tap on sensor bolt, you should hear the apc solenoid go crazy. if it doesn't, tap a little harder, but it shouldn't take much. if still no response from solenoid, remove connector from solenoid and slowly reconnect, soleoid should click/rattle. if it doesn't, your solenoid could be bad, or the wiring to the solenoid could be bad. also, could have bad ignition module (mounted across from apc, small rectangle). don't know how to test other than to replace with known good one and try again. if isn't working, the apc won't work and you'll only get base boost. finally, could be a bad apc, could try swapping with known good one. hope this helps, good luck.
