It could be possible of a bad MAF but unlikely based on the OP's symptoms as posted in which there appears to be no further driveability issues other than hard starting (2-3 seconds) not indicative of a bad MAF. Usually you will get excessively long over 5 second crank times and accompanying symptoms such as backfire, misfire, stallout and in many cases black smoke out the exhaust. Once started if it starts the idle will be very bad or erratic too.

I would concentrate on checking fuel pressure to make sure it is in specs and fuel filter as suggested and/or try to rule out the fuel pressure regulator which may cause the OP's symptoms.
