2000 db7 vantage running on left 6 cylinders only,, right side of engine not firing, checked all fuses relays etc.. 1st try was fuel pressure at fuel rail but have 65lbs per repair manual at the fuel rail.. This is a problem that seemed to have been solved by disconnecting the negative on the battery but now does not solve it. any thoughts or suggestions greatly appreciated by the 1st time poster..
Ok , update! Purchased a code scan device, ( pretty easy to use by the way) and guess what ,, po300 thru po306 , multiple engine cylinder misfire, really? I kew that already but it also said p0004 thru p0006 all related to fuel delivery! How can that be. I checked fuel pressure at the rail on the right side and had 65 psi,, well guess what, I didn't check the fuel rail pressure on the left (driver side) of the engine turns out the fuel rails are on opposite sides of the cylinders they are supplying! WTF! I guess it made sense to the designer,, would never have discovered it without the shop manual and code scan device,,, tested fuel pressure at the wheel well filter and still no pressure,, checked fuses again and I feel I am left with nothing but the secondary fuel pump which I am sure is a bear to remove from the fuel tank,,
Anyone have any thoughts or suggestions,, I'm sure that is all it can be at his point,, any input is greatly appreciated
