<sheepish grin> It was exactly that. Once I went home and got my tools, I
went back, put my meter on the battery.all good. I had the key in the
ignition, and when I wiggled the battery, everything lit up. Loose ground
cable. Looked for all the world like it had a good connection. Tightened it
down and we're in business.


Feel like a dork.  :-)

I'd guess a major loss of ground. Battery still have juice?

Hey guys,


Update on my '90 200tq project. I got everything back together underside and

the car is tight. Runs well, but has a weird buck at 1.7bar. Also, seems to

idle a little rough and probably rich as it failed an emissions test this

morning. All that is minor right now.


The REAL head-scratcher is that on the way back from the inspection station,

I stopped at a convenience store, and when I came back out, there was no

electrical power in the car at all. Turned the key; nothing. No accessory

power, no lights, nada. It is like there is no battery in the car.


So, the car is stuck at the store, my shop manuals are behind locked doors

at the wrench's shop, and I'm stumped. Any ideas?
