Default No crank, no start (solved)

Hey guys
picked up a 1999 for a good price.
Worked great until i just finished transferring the ownership to my name.
Turning the key to "start" dims the gauges, dash, and turns off the exterior lights and cabin fans (like its supposed to) but no crank on the starter.
I hear a relay click from the footwell area, so im guessing the ignition switch is ok.
Did a whole wack of reading on this forum, and gathered that I should check for 12V leading to the starter relay (yellow wire) when trying to crank.
Havent had a chance to get to that part yet, however was wondering if the ignition switch is bad, do you still get clicks coming from the relay in the footwell area?
Car runs just fine if I bump start it when rolling down a hill.

Default Replace the battery

Your battery died. Mine died the same way a few weeks ago. Ran fine when I parked it. Came back a couple of hours later and had the same symptoms you're seeing. I'd never seen a battery fail suddenly like that.

The the voltage of the battery with a VOM. It should be ~12.5 VDC. Then try to crank the engine and watch the VOM. My guess is that it's under 7 VDC in which case you need a new battery... Ron

Thanks to PMI
Do the service work, then the diagnostics.
Study your manual, the Haynes is so-so, at best, but it does help.
I have had a battery "die" suddenly - more or less.
But it was a condemned battery still being used, I expected it..

Sorry guys, i forgot to meantion that Im a little on the mechanically inclined side as we kinda have to be to own stuff like this.
Yeah the 1st thing I did was check to make sure the battery wastn low.
I had the battery charger on there topping it up, and trying to crank resulted in no voltage drop or anything to that effect. floating voltage is 12.6 and didnt move when trying to crank.
simply put, the starter itself isnt even trying.
The lights turn off by design when you try to crank so all available current goes to the starter. It did this even when the starter was actually working yesterday.

Well guys, I was in a way kind of hoping for more of an adventure, was ready to pull the ignition / twice unit. Figured I would check for voltage at the yellow wire leading into the starter solenoid. as i was inspecting it, the small length of wire (about 3 inches) leading from the relay to the starter motor fell apart in my hands. I guess the last time I started it was enough to burn it through completely.
Ive removed all the bolts to the starter, but its a little hard to remove. do you have to what it with a hammer or something?

Use some friendly persuasion on the motor(a ten pound hammer)
