Injector fitting

Finally picking up my Power Fc and AVCR next week.
So about time i fitted my injectors.
Is this easy DIY job?
Anyone got a guide?

Thanks

Move header tank out of way
Remove the plugs

when refitting be gentle with the 'o' rings and lub them with washing up liquid to make them easier to fit.
do not force them or they will trap/kink.

when fitted, turn engine on to prime fuel pump. With plugs removed check no excesive fuel is coming out of plug holes. If you have an FPR check it's reading pressure as normal

Then turn over over with plugs removed and check again for no excesive fuel coming out of plug holes.
this will confirm that they are sealed

Refit plugs and fire up.

If engine stops or locks during cranking you have a leak and 1 or many bores are now full of fuel. There is a risk of bending a rod if this happens. RobEvo5 done this but got away with no damage.

Nice one Scott
Thanks

Good luck - plugs out has to be the biggest tip.

When you remove the injectors you may well find the system is still pressurized a little and fuel will bubble over from the rail into the bores and will continue to do so for a bit filling up the bores.

Turn engine over with plugs removed and/or crank sensor disconnected to force this petrol out if its allot. Or if just a dribble it will evaporate by the time you have fitted the new ones.

If you can leave the car standing overnight and not prime the pump at any point and then do the job, it might/should avoid this problem.

If the injectors don't feel like its seated down correctly it probably hasn't. Oh and you might end up crimping an 'O' ring if your unluckly so you might want a spare 'o' ring or 2 to hand just in case.

And probably not a bad idea to have a fire extinguisher to hand just in case
