Ford Mustang Fuel Problems

[account_disabled]

When the temperature is below 50 degrees and the engine is COLD, on KOEO the fuel pump runs continuously. This prevents the engine from starting. If you leave the key on for a long period of time (greater than 10 minutes) the pump will stop and the car will start. However, the engine runs very rich (with low power) until it heats to normal operating temp. Replaced Fuel Relay, ECT, and wide open throttle relays. ECM reports secondary Fuel Pump Circuit Failure (code 95). At a lost on correcting this problem. What can I test or check next?

Any idea?

Please help.

Thanks!

I didn't find the right solution from the Internet.
