Lack of audible alarm and no fuel pump priming when key turned to start

[Bayliner288]

Hi, I'm hoping someone can help me troubleshoot my starting problem. I have a Bayliner 288 with a Mercruser 350 EFI. Today I tried starting it for the first time in a month, and although it would crank, it would not start. I noticed that the audible alarm did not sound, so I began checking fuses but didn't find any burned out. I also noticed that the fuel pump did not click like it would normally do when the fuel pump primes. I'm not sure if these two issues are connected, but assume they are and that it is more likely a fuse or electronics issue. Any help would be appreciated. Thanks.

Do we have a serial number (or year)?

Do you have an engine serial number, Bayliner 288 with a Merc 350 EFI means very little.

Sorry, it is a 2007 model, I don't know the serial number off hand but can get it tomorrow.

First place to look is the emergency tether (kill switch/deadman switch) it should be near your throttle/shift handle. If it is off or bad it will cause your symptoms.

I did make sure that the tether was in place and fully engaged, but I don't know how I would confirm the switch itself is not bad. Any advise?
