Car starts but stalls in under a minute almost always. Sometimes runs a little bit longer but still dies. What could cause this?

Scan for codes and check fuel pressure with a gauge clean throttle plate on both sides and iac hole with choke cleaner.

Fel pressure should be 35-45 psi and is low that may be the problem. Check for a vacuum leak as well especially if a hose goes to map sensor.
