Question about 1993 Saturn SL1
The engine dies when i press the brake.
It will idle fine until the brake is pressed
I just had this problem with my 97 sc1. I found that the driver's rear tail lights were staying on dim when ever the car was running. In my situation, the cluster of wires that ties to the rear tail light is also the wires that tie to the fuel pump. Every time you hit the brake, it shorted out and cut the power to the fuel pump. Test for this problem by pulling one of your tail light bulbs, if the car shuts off or wont start without it, this could be your problem.

You may have a defective power brake vacuum booster. The booster is the large, black circular item behind the brake master cylinder. It should have a large vacuum hose going from the booster to somewhere on the engine's intake manifold. Try clamping this hose completely shut using a small pair of needle nose Vise Grips. Make sure no air can pass through the hose. Try stepping on the brake pedal after doing this. If the problem goes away, you need to replace the brake booster.
