relieve fuel pressure

hey everyone i'm trying to replace the head gasket on my 02 altima 2.5s. i need to relieve fuel system pressure but the car doesn't start at this point so i can't pull the fuel pump relay and run the car. so i figured no problem i'll just relieve the pressure with the schrader valve on the fuel rail, which much to my surprise these cars don't have that so far as i can see. so what is the safest way to relieve the pressure without being able to start the car. i really appreciate any help anyone can give as i need to get this car back on the road asap.

Anytime I removed the fuel rail and injectors on my Honda I just opened the fuel cap and went on my way. Your not going to get soaked or lose all of your gas so what is a little gasoline on your hands and the ground?

Don't do it.
Do it the right way. Remember the line is under 51psi of pressure!!!!!

Fuel Pressure release procedure.
1. Pull the fuel pump fuse in the fuse box near the washer fluid. (IDPM E/R)
It should be a 15 amp fuse on the bottom front row. Second set of fuses on the lower row.(4 large fuses/ capacitors, then 2 rows, bottom row front fuse for a 3.5)
You will need to pull the fuse rail up to get to it probably. Look for tabs to release it I think
2. start engine
3. After engine stalls crank it 2-3 times to release all fuel pressure
4. turn off ignition
5. Remember to reinstall fuse when you hook it up. (cause Nissan tech's need to be told) lol
Good luck. Let me know if you need a picture.

Lol.. Trust me I pulled my fuel pump from just taking the gas cap off, and yes your fuel might spray a little bit. Just have shop rags ready and wrapped around the connector that you're disconnecting and you'll be fine. From my understanding uncapping your gas tank only relieved part of the system because there was still some pressure in the line. IT'S SAFE I PROMISE.
