Fuel Lines Pressure Release on 3.7 '07

[jja]

I am planning on removing the fuel tank. I have a FSM for KJ up to '05. There it says there's pressure in the fuel lines even when the engine is not running and that this pressure should be released before dis-assembly. The recommended procedure is removing the fuel pump fuse and starting the engine till it's not able to fire up any more.

Now, that all sounds reasonable. The problem is my '07 won't even crank after I remove the fuel pump fuse. It looks like something figures out there is no power for the fuel pump and refuses to start the car. So, is there a different procedure for releasing the fuel line pressure on after '05 models?

Just an old grease monkey here, but I've always just popped a line of and let em squirt a couple ounces. Was a lot more interesting back when I smoked!

Passenger side fuel rail there is a pressure test fitting,screw cap off and push in the shrader valve(fuel will spray,be careful).




Or you could just not use it for 24+ hours and by then all the pressure will have dissipated,just do not turn the key to run otherwise the pressure will build up again.

Thanks for the replies, guys.

Pushing the shrader valve pretty much amounts to popping the line in terms of mess created/fuel spilled. I kinda wanted to avoid spilling fuel as much as possible 'cause of the fire hazard.

Isn't there another way?

Put a couple of shop towels around the Schrader valve to catch the fuel...it won't be that much that you can't mop it up...
