It says in the workshop manual to disconnect the connector from the main relay at the left hand side of the cowl and and to bridge the blk/yellow and yellow/blk wires together. I did this removal about a year back and did not do this when installing a walbro. Does anyone know what this procedure does?

Thanks

 

Sorry my bad. That procedure is for "testing" the fuel pump. I guess it stops the fuel igniting or something along those lines.

Thanks </TD></TR></TABLE>the part about the jumper wire is for the testing of the fuel pump, not replacement - when you turn the ignition on, the fuel pump should run for about 2 seconds and then shut off - if the pump isn't coming on, what you are doing by jumping the wires is bypassing the Main Relay to see if you are getting power to the fuel pump - if the pump is running with the jumper connected, then you know it is not the pump and could be the Main Relay - if it still isn't running, you probe the wires at the pump to see if you have power - if you have power, then pump is bad
