I am awaiting the final resolution to this issue. I had already replaced my camshaft and crankshaft position sensor‘s and had the RCM rebuilt soul expected it to be a fuel delivery issue. My fuel filter was replaced with either BOSCH or MANN brand. I ordered a fuel pump but was waiting for Rupert to solve his issue before having mine installed. The car runs fine once started and usually starts well when cold Is it possible to install the fuel filter incorrectly and would it still allow the engine to run?
