Check for rapid drop in fuel pressure after the pump primes, and then shuts off. Should jump to at least 40psi when you turn the key is on, then pump shuts off after a couple seconds. Pressure should not drop rapidly, or it may cause extended start times. Turn the key on and off a few times before you try and start it. If it starts on the first attempt after that, it would also indicate a problem with the fuel system.
