Does anyone know what are common causes of blowing the fuse on the engine relay board for the fuel pump and how to diagnose it? Would a bad fuel pump cause this?
Thanks, |

The most common cause is that the aux air regulator wire is shorting to ground. Either where the wire goes into the bottom of the "can", or the wire is unplugged and touching ground that way.
