My dad's 1999 4 cylinder Ford Ranger doesn't always start. Usually when it doesn't start, seems like you just have to give it a couple of hours to cool down. The battery reads 12V so we know its not the battery. When this happens you simply hear a single tick upon turning the ignition key. However when we took it to auto zone they asked if the engine light was on. Since it is they hooked up the diagnostic tool which said P401 flow control valve. We bought a new EGR valve. I am unable to get the old one off. The mounting bolts came off easily, but the hose that gets screwed into it(believe it is called a EGR vacuum hose) will not break lose. Seems to be a 1 1/16 hex nut fit.
Does this connection spin free like a flare fitting, or is it solid on this steel EGR vacuum hose? If its solid I can see that I will have to disconnect the other end of the hose and snake it out. Either way it seems like it is going to take a crowfoot wrench to replace this valve.
Any help or suggestions greatly appreciated.
Thanks in advance!
