Just walked a house with non-twisted 4 pair. Looks just like every cat5 i've ever seen except it's not twisted.
The customer's router is about 20 feet away in another room across the hall and I have the wire in question going from the router to where I need to put a switch for a RTI XP-3.
So the question is will that wire support ethernet or am I running a new cat5

Did you get a chance to see description label printed on the wire jacket?
I'm highly suspicious the wire in question is Cat 3, which was designed to use for POT.

Put a cable tester on it and see what you get.

I'm pretty confident to say my Fluke Certifier would yield the speed test result as 10Base-T.

Everybody here is right.
It might work for you even if it doesn't meet the speed specs we want. If all you're doing is sending commands from/to an XP-3, maybe it's fast enough.
But you're putting in a switch, so perhaps you've left out the device that will need the highest speed. What else goes on that switch?

I'm working on a house built in 1931 and they used metal mesh lath & plaster, so WiFi sucks and there's no easy way to fish new cabling. Several of the rooms have surface-mounted phone jacks and when I toned the cables to the punch-down blocks, I saw 4 pair, so I decided to try one for internet. It worked, but before yesterday AM, I didn't know how well. Connected it to my laptop and did a speed test- came in at 49+MBs and he's paying for 50MBs. I couldn't see any cable markings, but I guess I got lucky. Maybe yours will work out as well.

20 feet? I'm betting it will work fine.

Do it. I have done POE over 4 pair untwisted pair stranded 24awg up to around 60-70 feet. I also have a Doorbird working flawlessly on POE over the same wire at close to the same distance. No issues with video or control.
You could always run something like iperf to test throughput. There are products out there that will send ethernet over 2 conductors of virtually any wire type you can imagine. Mobotix 2wire is one we have used a handful of times with no issues. There are others as well. But I would go ahead and use what you have first and just disclaim a plan B option to your client. :)
