Hmmm at the moment it has electronic ignition connected to the coil +ve and -ve. The pump is also connected to coil, but there is no relay. Just connected direct the same as the electronic ignition. This was the way that the garage in france set it up, so I did the same when I installed the new pump. Do I really need to run the pump from the battery instead of the coil? Cheers. Darrell.
