A couple of months ago, I noticed that my 97 TJ would talk a long time to start unless turning the key to on a couple of times because I was losing pressure in my fuel line. I replaced the fuel pressure regulator, and everything was fine again. Everything was perfect until a month and a half later, and now I am experiencing the same thing-I am losing fuel pressure. I attach the meter to the fuel rail and it reads
49 PSI at idle (which is good), but then when I shut it off the needle moves from 49 PSI to zero in a short period of time. Could this be that the part I bought (from Mopar) was defective, or that I have a new problem?
Thanks Mike
