I'm looking into changeing the spark plugs on my 1997 chrysler cirrus. It's a 2.5L V6 so i need to remove the intake manifold. I was wondering how important it is to relieve the fuel pressure before removing and disconnecting the fuel lines. I've heard there is two ways of doing so, 1) by removing the fuel pump fuse and cranking the engine and 2) disconnecting the connecter to thefuel rail/injector electrical harness connector and connecting a 12 volt source to Circuit A142. This is all outlined pretty well in the repair guide. But it does not say what kind of 12 volt source to use. Any help would be great. Thanks
