I have a 1994 Grand with 4.0 having some issues with starting. If you go out and start the Jeep for the first time in days no matter what the temp is she will whirl right over and run. Then drive it to work and if you go out every couple hours and start it PERFECT if you dont and you go out after work and try to start it she will take 8 or 9 tries then it will kick over and it acts as if it is flooded. Take is home let it sit for a day and it will whirl right over and run smooth. Garage has checked pressure to fuel rail great pressure and run mutiple test nobody can tell me what to do, So I put it to the best you guys. I know someone out there will figure it out. Thanks
Thanks for responding The jeep is a 6 cy 4.0 The 8 or 9 times turning over yea it is trying to start always starts just sometimes time consuming. Never died while running. Once ya get her started she is good to go. Gas consumption has increased some used to get around 20 mpg now down to about 18. Thanks for the help.
Thanks all you guys for the info the mechanic finally got aroung to unplugging the q2 sensor and the jeep is starting better not completely fixed but much better I think I will replace them both Thanks again
