I noticed it happens on hold ups/traffic jam. It goes off and wont start up, like its cutting fuel. When i leave it for sometime (5 min), it will start and run like normal. I have changed the fuel pump and filter. The temp guage is normal (mid point). I have this diagnostic kit and the codes on it are P1085, P0174, P1083, P1525, P0115, P0161, P0128, P0172. Please help.

Assuming the fuel pump is not defective and installed correctly, the next possible cause would be the fuel pump relay. I would clear all fault codes and replace the relay and drive it. . Questions call 617-773-3900. Doug
