I am currently trying to make my 1986 Range Rover 3.5 EFi run
propperly on petrol after having run only on LPG for 2 years. I
replaced the fuel lines which had rusted out as well as the fuel pump
but despite then running on petrol it was very rough compared to
opperation on LPG.
Today I have stripped down the fuel injection system and tested the
fuel injectors, 7 of them were opperational but had bits of rust in. I
pressure backflushed them and they now seem to opperate fine with what
appears to be a normal spray pattern. The eigth injector however will
not fire, it gets warm but the valve does not open so I assume the
coil has shorted or it's ceased up.
Does anyone have an old single injector lying around they would be
able to sell me to get the engine running again? As long as it
opperational it should be suffiecient seeing as petrol will only be
used for satrtup and when LPG is not available.
Another thing I noticed when removing the fuel system was that for as
long as I have had the vehicle the "Extra Air Valve" towards the front
of the inlet manifold has not been connected to the electrical
connector (which was lying loose). What would be the consequence of
this and could there be any reason it was disconnected?
