You need to troubleshoot the circuit. First check to see if the switch mounted on the accelerator arm is in position and adjusted. Mine was busted and the retainer clip was missing. Have someone floor the gas pedal WITH THE ENGINE OFF and see if the switch is contacting the firewall. If it is, pull off the plug to the switch and check with an ohm meter to see if the two terminals on the switch go from open to shorted when the pedal is pressed. If so, your switch is adjusted and working. Thats a good place to start. If that looks ok, turn the key on WITH THE ENGINE OFF , disconnect the connector going into the hood to the solenoid and have someone mash the pedal WITH THE ENGINE OFF. Check to see if there is 12 volts on that connector. If you do, the system is working correctly and the solenoid is probably bad. If not you may have a bad relay, which should be on the firewall a few inches to the right of the heater core. You should also check the connections at the fuse box where the system gets the 12 volts. If it's a factoy system the harness should penetrate the firewall just above the fuse box and have two connectors that plug into the fuse side of the box. Good luck, let us know what you find.
