Chevrolet Captiva 2013 2.4 LT Automatic 30000 miles
8L of Diesel was added to the tank by mistake, car drove for a while then stalled. Tank was emptied and refuelled with petrol. Since then car won't start. Fuel pump working perfect, new spark plugs fitted but car just cranks, no start. Engine fault light not coming on to indicate fault. But when you plug Diagnosis machine ECU shows that all possible error messages. Changed ECU, initially no error was shown, after trying to start the car many times without success, new ECU also displayed same error messages as the old one. What can be wrong?
