My mystery, and choose your own adventure, if you choose to aceept.
The story starts one morning, a warm 12 degrees in Melbourne. Turn the car over it starts but only gets to about 800 revs and dies, repeat times 5 and the bus becomes the next option. At this point i did have approx 50km in the tank car on a slight angle, low fuel....mmm. So put an extra 20 ltrs in, same outcome. Almost like it's not getting fuel, so this leads me on a path. The fun begins, pack snacks if you choose to turn the page. The next bit, like a demtel add has been fast forwarded for the purposes of not boring everyone, replace fuel filter, confirmed fuel not contaminated, confirmed fuel pump sprays a like a happy dog, changed sensor on tank but alas no change or outcome. What do they say, try a 1000 things and get the same outcome makes you an idiot, or at least i think that's how the frustrated home mechanic thinks. When testing the pressure from the common rail and turning over, the fuel limps out, aha, aha, maybe source of problem. Low pressure or non from high pressure fuel pump. At this point, this home mechanic knows he's out of his depth and specialist tools.
my challenge, and OBD-II tool shows no errors, surely a low fuel flow would be picked up by the tool or the car self checks would pick up an engine warning at the sensors in the common rail and/or high flow fuel pump? Before i do down the road of paying a mechanic to replace the high flow diesel pump, could it be as simple as a sensor, how would i know or test this.
Please lend me your thoughts. I promise all replies will come with dad humor and dull wit.
