92 ACCORD what causes the gauges to quit working when the brake pedal is depressed, another problem is turning on the headlights and the engine dies any answer's ?

Hi Christopher:
I'd be checking to make sure that the grounds are nice and clean and working properly. When you step on the brake pedal you are activating a switch that sends power to the brake lights. The brake lights share bulbs with the signals and emergency flashers, so it is also possible that a dead short in any of those components could "steal" the power from the ignition.
At this point, it's a trouble shoot game for you to figure out what is working, and what is not.
That's part of the fun. Enjoy.

1992 Buick Park Ave. won't start after pressing brake pedal.

sometimes the other switch is to cut out the cruise control when the brake is applied. I would more suspect something in the fuel injection controls such as a mass air flow sensor or throttle "switch." your car is probably too old to have an auxiliary air bypass valve but if it has one look at it as well. good luck

Abs light is on and brakes keep getting tighter

bad brakes. (do explain tighter?) (to a blind, no leg man)
first fix bad brakes, then worry ABS. last
explain tighter.
in driving school , they teach , how to drive (safely) with a stalled engine
as the engine stalls. and vacuum hits zero, the booster slowly
dies and bingo , old fashion , manual brakes. (stalls are like that)
is that what is happening. engine stalls?, or the booster is failing?
what happens there is brakes are 100 ok, but just harder to press
the pedal so you press harder and brakes are ALL THERE.
the is all by DESIGN.. no accident (no pun)
see if you have any other bad brakes symptoms.
like these.

if brakes are 100% ok then , run the ABS scan or diagnostic
stated in the FSM , see what code you are getting.
then post that. ABS can not function correctly with bad brakes.

4 cyl Engine starts and idles ok...give it throttle and it dies

I need to get a clear mental picture of what exactly is happening.

With this said, you stated that the car "runs fine" until warmed up.

Q: When you start the car when cold it idles fine?
Q: If you allow the car to idle until "fully" warmed does the car stall?
Q: As the car begins to warm up, Does the RPM fluctuate abnormally?
Q: Does the car Only stall when you press on the gas pedal or does it stall just sitting and idling in addition to pressing the gas pedal?
Q: If you can drive it while cold does the car stall during acceleration when warm or only at Stop Signs / Lights?
Q: If you wait 20min or so, can you start the car again?
Q: How many miles are on the car?

the ignition will come on as the engine will have stalled whats happening is when you press the brake the brake servo is taking all the vacuum out of the inlet manifold causing the engine to stall does your brake pedal feel ok because the usuall cause of this problem is the brake master cylinder is leaking brake fliud into the servo the fluid gets sucked into the inlet manifold causing it to get blown out of the exaust replace the master cylnder try again yates210456
