Hi all I've got a 2011 chevvy cpqtiva 2.2d ltz had an issue with rough idle and intermittent cutting out while driving. Diagnostic put it down as the fuel pump rear bought an OEM part new had it fitted, ran fine for about 2 weeks then same issue, management light on rough idle and stalling out. Was then told fuel relay so put an OEM relay in, nothing. You can hear the pump priming sometimes most of the time not, so im guessing fuel issue at the rail, faulty pump/fuel relay or bigger electrical issue. Any ideas would be greatly appreciated
