#5 of 11 Now there's a buzzing noise...

Thank you, cutehumor. After I cleaned the cables, the lights come on, horn blows, etc. but when I turn the key, there's just a buzzing noise, no clicking or anything, just some kind of buzzing. And still won't start...H E L P!!!!

I would wait at least 1-2 hours after cleaning the terminals of corrosion before starting so the alternator can get power from the battery. since the car didn't have any power at all for two days. It's a good sign that you got lights on. does the car turn over at all?

It wasn't turning over or anything but I tapped the cables down a little more and the car started afterwards. Sorry for my naiveness but it's a learning experience for me. Thank you very much for your help!!!

It looked like your problem was that the terminal connectors were corroded. After the cleaning, the connectors were not on the battery terminals all the way that's why the lights worked, horn, but not enough power to crank. I'm glad the problem is solved. Now make sure the battery terminal connectors are screwed on tight so they aren't jarred loose while driving. Usually there is a locknut screw that secures the battery connectors onto the battery terminals.

Could be a bad Crankshaft Position Sensor.
cute... Mitsu Mirage battery terminals love to corrode. This has happened on my sister's '93 Plymouth Colt on several occasions, causing nothing to work, or the car to start. Right now, they're corroded again, and are about to get cleaned.
#11 of 11 940 Starting Problem
Aug 20, 2003 (10:53 am)
Have your mechanic check out the "impulse sensor" at the back of the engine. I had a similar problem with a 940 that would not start when hot, that was cured by replacing the impulse sensor. It reads flywheel revolutions and triggers the ignition. The cost is $53-63 and Chilton's Flat Rate Manual says time involved is one half hour.
Had an unfortunate experience with the repair at Jaffarian Volvo in Haverhill, MA. They claimed the repair took 4 hours and overcharged by 3-1/2 hours times a hefty labor rate. Be interested to hear how you make out.
