ENGINE RUNS FOR ABOUT 3-4 MINS, THEN CUTS OUT. TRACED FAULT DOWN TO ELECTRICAL RELAY ON N/S INNER WING. RELAY TRIPPING OUT AND LOOSING FEED TO ECU/PUMP. THIS RELAY IS PULLED IN BY WIRE RUNNING FROM INERTIA WHICH APPEARS TO BE + AND THE OTHER SIDE FROM ECU WHICH GIVES A FLASHING -. CAN ANY ONE GIVE FURTHER DETAIL, OR HAD SIMILAR PROBLEM. HAVE YOU GOT A WIRING DIAGRAM?? DO YOU KNOW WHERE THE WIRE TO THE INERTIA COMES FROM OR WHAT THE APPARENT NEG WIRE FROM THE ECU IS DOING - IS IT SOMETHING TO DO WITH THE IMMOBILISER ?? DONE TEMPORARY REPAIR BY REMOVING RELAY, AND BRIDGING FEED TO SUPPLY ECU/PUMP. CUSTOMER HAS TO KEEP UNPLUGGING WHEN PARKED UP. IF PROBLEM WITH IMMOBILISER, CAN THE RELAY BE FED BY AN IGNITION SWITCHED FEED. ANY HELP MUCH APPRECIATED. KIND REGARDS PHIL N
