Going through the steps using the Bently manual I must of accidently cross two connectors on the double relay using my multi meter shorting the ECU.  Apparently this effected the fuel pump relay circuitry which the ECU would complete ground. Question can this ECU be repaired by identifying the faulty electronic component and replace it? I also purchased a used but good computer but the numbers are different. My 82 Westy is a California emission vehicle and most part numbers are different from the other 49 states. The original ECU number is 071-906-021B (California model) and the one I replaced it with was a federal model 039-906-021D. The Van is running OK but I notice an increase in fuel consumption aprox 1.5-2 mpg. Will the Van pass emissions next time around and  will it cause problems to the engine? One last question does the computer electronically advance the distributor timing? The reason why I ask is when I accelerate the engine and use a timing light the timing mark goes all the way to 40 degs. BTC the Bently manual says different. Please provide some helpful feedback?
