You may have pressure in the system, but the system will only work properly within a narrow pressure range - too low or too high will cause problems. Have the fuel pressure checked over several operating conditions (pressure too low is usually the pump or a rubber connector in the fuel line collapsing under high engine load, too high is usually the regulator).

1990 chevy corsica 3.1 engine, car starts but dies, will not stay running


Could be a long list of components including relays and the ignition module.
You'll have to figure out if it is loosing fuel pressure or spark to the plugs to proceed.
Is the check engine light staying on when the engine is running ?

Where is the fuel pressure regulator on a 1991 chevy corsica?


under the intake manifold between the fuel rails to replace you need to remove atleast one of the fuel rails to spread them apart for the regulator its not a very hard thing to do just be careful with removing the intake

Coils and wires are the most likely culprits as they never get replaced hardly ever. You cant really test a coil, you can check for resistance on the plug wires but that doesnt tell you if the insulation is bad on them.

93 chevy corsica. problem is after startup gas just pours out of the throttle body intake as the car stalls - probably half o cup of gas pours out. Is an injector stuck open? any advice?


Yes, most likely cause is an injector is stuck. The real problem is that you are removing the oil from the upper engine and it's protection with this issue.
Fix it forthwith, and when done, change the oil...it has been diluted by fuel...
