How do I check my fuel pressure without a tester?
Disconnect the hose coming from the pump to the filter and block the passage of the hose tightly with your finger. You can then start the car. If you feel that the fuel is pushing your finger hard, it means you have good pressure. If not, then you require replacing the pump.

This test is only necessary if other pressure tests indicate lower than normal fuel pressure. CAUTION: Perform this test only long enough to determine if pressure rises above minimum specification; risk exists of blowing coupler hose off of pump.
