screwbaru2 Posted August 1, 2013 Share Posted August 1, 2013 I recently had a fuel delivery issue with my 2003 OB 3.0. We were driving when suddenly the engine quit and wouldn't start. I was able to isolate it as fuel delivery by spraying a small amount of starting fluid into the intake duct ahead of the air filter. This allowed the engine to fire and run just long enough to determine that everything was firing. So off to the PC I went to use the most useful diagnostic tool I have: USMB. A search on H6 3.0 fuel delivery produced no less than 6 of the same issues! I checked the citied "cap" and sure enough it was cracked and mostly likely leaking not allowing pressure to build up or the chamber to fill. I ordered a new OME pump installed it today and Voila! My screwbaru is running! Just wanted to add my issue to the others and thank you all at USMB for a fine and useful site! Quote Link to comment Share on other sites More sharing options...
1 Lucky Texan Posted August 1, 2013 Share Posted August 1, 2013 Save your old pump assembly - for about $60, it can be fixed up with a cap for the 04 (which is longer but fits just fine) and an $0.80 o-ring. Quote Link to comment Share on other sites More sharing options...

Cougar Posted August 23, 2013 Share Posted August 23, 2013 I think I remember reading something about this issue. This cracked "cap" that is mentioned, is it located on the fuel pump? Quote Link to comment Share on other sites More sharing options...
