Car would not crank if the main relay blew, nothing would work hence why it is called the main relay.

Before we diagnose a no-start, let's look at how Honda's main relay works. The relay is a dual relay, that is to say that it is two relays in one. The first relay powers up the computer and supplies power for the second relay. Once the computer is powered up, it will ground the second relay, which supplies power to the fuel pump. There are three conditions that will cause the computer to activate the fuel-pump half of the main relay:

• When the key is turned on, the computer will run the fuel pump for two seconds.
• When the starter is engaged.
• When there is a tach signal to the computer.

So when it clicks once, thats the computer and everything else running...the second click is the fuel pump. Therefore it's possible for the car to crank but not start if the fuel pump 1/2 of the main relay is bad. Which is exactly what it sounds like he's describing.
