Sudden Death/Nostart: gauges dead-still. Not FP or Relay

So, I'm driving my TJ down a very busy intersection's left turn lane (one of two), and the whole thing just goes DIW. (Dead In Water) Turn on key, no fuel pump spin-up, fuel gauge motionless. (In fact, all needles are, but it doesn't start so they probably wouldnt move yet. Need to recheck- But definitely dead-still fuel gauge.) Idiot lights work, (pre-start instruments), but no gauge movement. Absolutely no starting effort. Haven't pulled codes yet, if any. Will after breakfast.

97 TJ 2.5L Auto, 160,000 plus miles, fuel pump sounded like a turbine engine a few months ago anyway, so just changed it out yesterday while it's inop. (bench tested old one, was still working.) Reattached all connectors, no change in gauges, still no FP spin-up.

Nada. Zilch. It's a gaint paper-weight.

Any insight will be greatly appreciated. It's my DD. I'm renting a car for the duration.

Thank you, in advance.

Test your battery with a Multimeter....if its not charging and is dead, it will do just what you describe.

Thanks for responding, Dex. No joy. Battery is taking cahrge well, and just in case there was something wiggy with it, I switched it our for a known good battery, also with no luck.

This might be... well.. a problem. Linked into my OBDII scanner, and it doesn't see the ECU.

I've tried the "Jiggle the black plug" approach seen elsewhere here, removed and replaced it, but still nothing, so far.

I'm thinking stealership. Man, I hate to do this... It could be a fuse, and it's still going to somehow miraculously cost me $1500.

Well, that pretty much validates my point, now doesn't it...
