[QUOTE="Raeverd, post: 435373, member: 20394"] Ok guys after replacing the cps twice it needed up not being a faulty sensor. After putting the new one in it wouldn’t even start and had to be towed home. Again. Checked the fuel pressure on the rail and there really wasn’t any this time and I could not hear the fuel pump kick on. So I replaced the pump. Started right up. Took it for a test drive and got about 3 miles and it died. Then the 3 miles back home it died 6 more times. But this time the engine had a rough idle to it. So I got a new fuel filter and just replaced it. Pulled out of the drive way and it died. Took it down the road a bit and it did fine. Now I’m on another test run with it and about 5 miles into it it has died 2 times already. Each time it won’t start I’ve replaced the map sensor, cps, fuel pump and fuel filter and after each one it starts right up and drives for a bit. Sometimes it will go less then a half mile sometimes it will go 20 miles. I’m at a loss. I don’t know what I should check next. I don’t have any codes and my check engine light doesn’t come on. But after changing the fuel filter the rough idle went away. [/QUOTE]
