Default 2007 DF300 - Cranks, no start

Well, as the title states I’m having issues with my 2007 DF300’s (twins - fly by wire) on my Intrepid.

The symptoms are the following:

Upon turning the key on the “ON” position all the gauges turn on as normal however I get a “low voltage” alarm. Engines will crank/turn over but I don’t hear the fuel pumps kick on and obviously the engines will not start. Trim works fine - engines will go up and down.

So far, I’ve checked all the harness connections, battery voltage, checked the white wire connections and all associated fuses in addition to all fuses on the engines. I also replaced the ignition switch and kill switch with factory parts and still have the same issue.

Prior to this problem I have had no issues whatsoever. Boat has been sitting for maybe three weeks since it was used last.

Im looking for some help as to maybe if I’m missing something. Any feedback is appreciated!

Yes, I’ve also checked the neural safety switch.
All is well.

Fuel pumps are not working with key on? Check fuses under cowling.

As my post stated, all has been checked. All fuses on the boat are good.

Cranking without starting sounds like a fuel issue, so obviously bad fuel or since you mentioned the pumps do not run it could be coincidentally both bad fuel pumps or electrical. I would consider bringing to a dealer since you tried all the basic things already, you might be looking at internal harness issues or bad wire somewhere in the system.
