My 1996 Chevy Camaro was running fine, up until last night. About halfway through my normal commute (70 miles), the gauges started bouncing all around and then the car stalled while driving. Pulling over, the engine would crank and start, but then instantly died, as soon as I released the key from the starting position. Any ideas?

I have a 1994 Chevrolet camaro when i crank it up the service engine soon light stay on and my car stalling for gas and then when i drive it complete cut off

Hi

If your car stalled while you were driving it, look for an obvious reason first. Check to make sure you have fuel in the tank (if your gas gauge is working). Do not sit there and crank the car over, trying to get it to start, as you will quickly wear down the battery if it's not already bad.
Check the probable causes for this kind of problems:-
Ignition
The ignition system is composed of: ignition switch, neutral safety switch, security bypass, plugs, wires (if applicable) and a coil, or in the case of coil-over systems, many coils. The ignition is also tied into the computer. The crank and cam sensors tell the engine where top dead center is. Though these sensors do not usually cause a no start, if they break, the computer will go into "limp home mode," which allows you to get the car to a service station. The car will run badly, and may stall out on you. If the plug wires, plugs or coils are bad and are causing the engine to misfire, the engine will run rough. This may also cause the car to stall when driving. Generally, it will start back up, but it may be difficult to keep the car running.
Fuel
The fuel system is composed of a fuel pump, fuel filters, and fuel injectors or a carburetor. Some cars have a throttle body---this looks similar to a carburetor and has only one or two fuel injectors in the middle of it. The injectors feed all of the cylinders. In a multi-port system, each cylinder has its own injector. Should the fuel pump go bad, the car will stall while you are driving, as no fuel is getting pumped up to the engine. Bad injectors in a multi-port system will make the car run rough, which can cause a stalling situation, but generally, the car will restart.
Other Problems
There are other problems that can make a car stall---in the ignition system, the fuel system or in the drivetrain. If the timing belt breaks, the car will stall. If the computer itself stops working, the car will stall. Neither item will allow a car to start back up until it is repaired.All vehicles have an idle air motor or valve. The idle air is governed by the computer and changes the idle. When you turn on the air compressor, you use some engine resources. This makes the idle speed on the engine drop. The computer senses this drop and sends information to the idle air to turn up the idle so the car does not stall. If this part breaks, when you slow down to a stop or to turn a corner, the car may stall.
Because the running of a vehicle is complicated, there are many more things that can cause a vehicle to stall. These are the most common things that can cause a car to stall. Other things include wiring, fuses, relays, other sensors not working properly or at all, a bad alternator or a bad battery, or an overheating problem, just to name a few.
