Fuel Gauge Not Working

I've had my new-to-me 2002 X-Star for a couple weeks and I'm trying to slowly check off the few issues that it's got.

The fuel gauge doesn't register at all. I'm thinking it's the sender unit. Does that sound logical? If so, isn't that easily accessible under the back center cushion?

Yes, you can get to it under the back center cushion. It's an easy swap.

Yes...do you think that's the issue, or just yes...it's easy to get to?

It's logical but it's statistically less likely to be the sender vs. being the gauge itself or the MDC (the black box under the dash). I'd test the sender first since it's easy to test with an ohm meter.

Question #1: If it's the MDC would it affect more than just the fuel gauge?

Question #2: How do I test the current one with an ohm meter?

If you have a two wire sender check out this thread. It should help.

#1: No. Sometimes they fail in such a manner to only affect a subset of the gauges. That's why it's so hard to troubleshoot.

If it turns out to be the sender I would not buy the OE 3 wire Centroid sender. Get a 2 wire Wema SSS of appropriate length for your tank. It's better and cheaper.

The only other gauge that's not working is my Perfect Pass display. Any chance you think these two things are related?

Unlikely they are related. Im currently dealing with the same exact issues. Just put in a new 3 wire sender and guage still doesnt work. The needle just stays on empty. Im researching my next move.
Perfect pass should have a buss fuse under the dash, check that first.
