Need help my eclipse after a long day of driving around went and parked it at the track at 7:00 came back around 10 at night and didn't wanna start up so i cranked it a few times and it started up on the fourth try (first time it has ever done that) then i was driving back home and cruzing at like 2900 to 2600RPM started to buck on me like a wild horse and when i got to the toll and put it back to neutral it completely shut off on me. Then i started back up and only two pistons were getting fuel and piston # 3 and 4 are just knocking and my fuel pump is not getting any electricity and have all ready tried two fuel pumps. PLz some1 help
