My Liberty will run for awhile at idle sitting in driveway as soon as I go to drive it down the road it will shut off but will restart run a little more then do the same thing all over again. I did the weeks 1&2 kit to do away with the egr valve completely run the truck again in drive way to check over everything to make sure there was no leaks and it was find as soon as I drove. Down the street it shut of but this time it didn't restart. The switch or whatever it is called at the end of the fuel rail by the firewall was making a noise almost like grinding I towed it home and left it over night and it started up and ran fine but I didn't drive it afraid of breaking down again. Could the switch or part be my problem? Is that the fuel shut of? Can anyone let me know what it is called so I can find it and order one? Or is that not my problem . What should I look for?
Thanks pal
