Question about Geo Cars & Trucks
Spray some throttle cleaner into the throttle to clean it out. It will also clean the IAC valve. See if that will help you. You may need to have a scanner hooked up to see what is happening to the fuel system.

Check and clean Idle air control valve. Make sure its responding to signal as well. Also make sure ther are no vacuum hoses disconnected. This may not be a "cure" but it's a good place to start.

Have the idle bypass valve checked, also called idle air control valve.
If that valve is stuck in the closed position, it's not allowing the fuel to bypass the throttle plate to keep it idling, resulting in stalling, but will keep engine running if the pedal is pushed down.

it sounds like fuel pump is going. pressure should be around 40 psi.
Or it could be flooding. Holding gas pedal to floor during cranking of the engine, shuts off fuel flow through the injectors to clear a flooded engine. After engine is running again, it lets fuel flow.
If you have a Mass Air Flow Sensor in the iar intake tube, clean it with spray carb cleaner several times.
Also, try disconnecting the oxygen sensor to see if it helps. It will turn your check engine light on, but you can cycle key from off to "on" 40 times to turn it off.

The Idle Air Control (IAC) is not working.... This is a very common problem and very easy to fix. The IAC will run you about $50 (USD) and the only tools needed is a 8mm socket. Disconnect the electrical connector, remove the 2 8mm hex screws, remove IAC. Reverse order to install.
It looks like the picture below
