Answer 1
wow, none of those parts had anything to do with the issue. i would look at fuel pressure. if the pressure is low when it is hot, then yes, it could be a fuel delivery issue. have a shop verify it before throwing more parts at it that have nothing to do with the repair. Roy -

FUEL HAS PRESSURE.PARTS ARE FROM CODES COMING FROM COMPUTER DIAGNOSTICS. CAR IS IN SHOP!! CAR HAS BEEN TO 3 SHOPS!! -
Comment 2
you may have pressure but what is the pressure?? code numbers never identify failed parts, just failed systems. I hope the parts replaced were from an actual diag, not just the codes. hard to believe that 3 shops cannot figure this out. it is a somewhat common issue with low fuel pressure. Roy -
