Problem after injector change
Hey there I installed some new injectors today all went well untill i went to start the car I waited for the fuel pump but I heard spraying coming from the engine Now 1 of the injectors on the passenger side wont seal Ive tried new o rings and old ones still wont sealIve reseated them about 4 times now with no luck.
wheres it leaking from exactly
It was from the top of the injector I ended up using one of my old o rings which still looked good and its now sealing 3 o rings later Taken it for a decent drive all is fine now
fixed again slight bend in fule rail making the injector sit on an angle not sealing

Did u lube the o rings when fitting the injectors or smash them in dry?

Are you sure you removed the old o ring from the injector rail. You should never reuse the o rings when you do the injectors.
Welcome to the internet where people have opinions that you might not like
They are all new o-rings One of the out lets on the fuel rail was slightly bent so that one injector was not sitting inline I placed a old injector in that spot and slightly bent it back in Wasnt hard to bend Seems fine now been driving and no sign of leaking fuel It also looks more alligned now. 3rd car ive done them on only this one gave me problems
Still going good not leaking But when i was doing the job i noticed a split in the vacuum hose from the fuel pressure regulator to the plenum So i went and bought another when i got home i noticed its only about 5 mm and the stock one was about 6-7 Would this matter cause its now rough on start like its going to stall for a split second then bang it starts.

Replaced hose back to the normal size still rough start. Fuel around town is now 15L/100k as 13.5 before :S

Could have a leaky injector. If you run it for a while then turn off and straight back on again does it start nice?

Yep It will start better after its been running for say 10 mins or so. Thought one might have been a bit leaky But they are all very clean around the o-rings as i degreased the inlet manifold while i did the gasket so its easy to tell.

Leaking as in the injector isnt closing properly and is dribbling fuel into the cylinder

It starts first go not a cranking problem just rough idle on start for a few seconds I went to start it yesterday and heard a air discharge Opened the bonnet to find the vacume hose had poped it self off and i could slide the hose out of its sleeve I matched the ends up pluged it back in 2 good starts now out of 3 Time to try a new one
