RX3 won't start and I can't figure out why......

The battery voltage may be good, but a load test will tell you its true condition. Take it to an auto parts store and have them load test it, just to be sure.

....and of course, loose battery terminals can cause all kinds of weird symptoms in an EFI unit.

Ok sorry it took so long to get back to you all.

1st replaced the battery the other one was toast.
2nd replaced the spark plug the old one was very dirty.
3rd yes the fuel pump is spooling up every time I turn the key over.
It turns and turns and turns but it won't light off.
Every 5th or 6th time I try to start it, it will turn over and sputter then die. The rest of the time the starter just turns and turns..

There is gas in the bike and I've checked all the connections I have no idea where else to look...

This is getting beyond frustrating...

I’m no mechanic, but are you getting strong spark to the wire, and maybe a fuel line is kinked under the tank. You either aren’t getting spark or gas, if it sputters and dies. I’d disconnect the fuel line, and turn the key on, see if you’re getting pressure. I’m sure there’s a tool for this, but sometimes you just gotta make do with what you’ve got at hand.

I was thinking the same thing.

During one of my many valve checks, I remounted the gas tank with the fuel line kinked.

The engine would turn over and over but not start.

I thought there may be a fuel tip-over switch that was triggered when I removed the tank (there isn't).

Called CSC, and Gerry put me on to the kinked fuel line.

Removed the tank, straightened the fuel line, and the engine started right up.

That is something I will definitely look at. I'll take off the fuel tank in the morning and see if there's a pinched or kinked line. However I haven't taken off the fuel tank in over 1000 miles so I'm not so sure that's the issue. But it dang sure can't hurt to check! At this point I have no idea what else to do.....

Probably not.

My no-start happened immediately after remounting the tank.

While you were replacing the spark plug, did you check for spark?
