99 subaru forester. No power at all. When I wiggle negative battery cable : power comes back and alarm is triggered. But power fails again if I turn key or touch brake pedal. How do i fix this?

Bad battery (have the battery tested) Bad connection, corrosion on the terminal and in the cable, replace the cable, recharge the battery to full charge.

GM '97 Buick Le Sabre Climate Control flashing display

I did the exact thing with my '98 buick LeSabere. I am certain that the dealer would have to look at the components and relays and fuses. I had problems with Precision tune mechanics telling me there is nothing wrong with the electrical system, even though I still get a Flashing temp gauge and do not get FULL heat even when it's blasted to 90ºf . [Precision Tune got heat on the windshield and floor.] Moreover, the car is possessed with glitches; I am not getting heat on the windshield and the floor is not hot enough to warm the cabin.

2003 Saturn L200- sometimes when you turn the key and try to start there is nothing, turn the key again and the car starts. smoetimes this happens 2 or 3 times a day?

HI, i recommend checking the battery cables and battery posts as well. make sure the cables are screwed tight on the post and there is no visible corrosion on the battery terminals as well.

When checking the cables, make sure the negative cable is tightly secured and screwed down tight. maker sure the positive cable is in god position as well.

There is a wire on the starter that can become loose over time so, slide under this car and check the starter wires as well for tight and secure fit also.

If the battery terminals are free of corrosion and the cables are secured and screwed to there respective connections tightly, i will then recommend you move your inspection to the ignition switch inside the car.

Most likely, this will be the problem spot if everything above checks out ok.

At this point, i suggest replacing the entire ignition switch at this point.

Please rate and god bless:)

Car engine shuts off by itself, now it won't start!!

Although it would be an unusual problem, I would have the alternator checked and even buy a low-cost digital voltmeter from Radio Shack or an auto parts store; these cost under $20 and would let you monitor the on board voltage to watch for glitches your dashboard meter will miss since it is heavily 'damped' to prevent the needle from bouncing around while traveling rough roads. Having one of these multimeters will also let you monitor the battery voltage while trying to start and verify correct charge voltage from the alternator while the engine is running; it should be somewhere between 13-14.7 volts depending on the battery's state of charge. A healthy battery, when charged, will settle at around 12.6 volts after sitting for a while with the engine off. They will measure a little higher right after turning the engine off.   
Our alternators have high-current diodes internally and one of these (there are 3-6 diodes) may be shorting at random badly enough to drag the 12V system down far enough to cause the computer and/or the ignition to fail momentarily.
You should also remove the battery clamps, ALWAYS(!) negative (ground) first, and use a battery terminal brush to clean the terminals of the battery and the inside of the clamps. Once your hands are dirty, remove the other ends of the battery cables too and using a steel brush, scrub the corrosion from those ends too.  The ground cable will go either to the engine block, then chassis or vice versa and both of their terminations should be cleaned.     
I've had these diodes die (short) so that they drained the battery in only a brief time.

Trying to start a 1994 Olds Cutlass Supreme and wont turn over.

Does it crank at all or is there nothing when you turn the key? If the resistor chips in the key(s) are bad, they shut down the fuel system for 3 minutes and it won't crank. I've had this happen and the problem was solved when I got new keys.
