Hey,

Gonna change #1 & #2 injectors today, I have read the guide on q45.org, but didnt see anything about depressureizing the fuel rail, if that needs to be done? I got the part covered about removing the injectors carefully, just not sure about the injectors having pressure or not. I allready learned my lesson doing the fuel filter and not taking off the battery lead first.

Thanks, Hopefully i'll get an answer this time? Been hard to get a reply lately here?

Ronnie

Do a search here occasionally.

Fuel system is pressurized. Don't forget the gas cap too.

Pull the fuel pump fuse... At idle.. Then crank it a few times after it dies.
