Hello,

I have a an optimax that blows the fuel pump fuse when the key is turned on. I have checked relays, checked grounds at the engine, checked connectors. So looking for additional troubleshooting ideas.

Pull connector on fuel pump.
If fuse doesn't blow when you turn the key, you have a bad fuel pump

Thanks! I got it figured out yesterday. The fuel pump in vapor separator was bad causing the fuse to blow
