Hi, thanks for writing in. You will need to check the fuel pressure on the fuel pressure port on the engine fuel rail. The pump should be producing at least 56 to 62 psi for SFI engine. If pressure is low or no pressure then replace the pump and filter. You may also need to replace the fuel pump connector. If you would like help, consider having an expert automotive technician from YourMechanic come to your home or office to inspect and diagnose this issue for you, and make or suggest any repairs as needed.
