Most common location is the under hood breaker box. disconnect + battery terminal...1) Remove box and clean the large screw that connects to contact under box. it gets dirty and grease builds up...2) using ohm meter set on lowest scale measure from - battery to both chassis and engine block...must read less than 50 ohms...if you read 2500 ohms (Example) there is a bad ground from battery to fender, firewall and engine block...You can purchase ground straps...Install straps from - battery terminal to both frame and block...3) check for frayed wiring harness from steering column by emergency break...4) Disconnect all connectors to PCM and clean contacts with DeOxit (radio shack carries this product) ...These are the common faults...If this list does not yield a fix let me know...saailer
