- 2010 Buick Lacrosse
I have a 2010 Lacrosse that recently died on me suddenly. It acted like it wasn't getting fuel. It turned over but wouldn't start. I had it towed to a garage and they diagnosed it as a bad high pressure fuel pump. I went back to the repair garage to get something out of the car and before the work was performed and it started right up. After the fuel pump was replaced it ran great for a couple of weeks. Then after filling up one day it starting acting up again. It stalled and I got it to restart but it sputtered then began to run OK. After doing this 3 times I pulled into a open parking lot and called my wife to come get me. While waiting for her, I started it up later and and it ran fine. I took it back to the garage and and had my wife follow me. The car started and ran perfectly while at the garage. After a couple of days I picked it up with no additional work being done. Then after a week it did it again. It was after filling up, but about 30 miles after filling up. This time I had to have it towed to the garage. The mechanic said it started right up when they checked it after being towed to the garage. He said he needed it to fail while on a scanner. I told him to drive it until it stopped a gain so he could diagnose and fix it. After two weeks it still ran perfectly. I picked it up last night and it was almost empty. I wonder if this has something to do with a fill - up. I understand that there is a second "low pressure" fuel pump in the gad tank - perhaps it is the second pump.
This is very frustrating - please let me know if there is anyone out there that experienced this problem and how it was fixed
