So for the average cash-strapped Rover SD1 Efi owner there is plenty of scope to reduce the cost of testing, servicing and even replacement of their Fuel Injectors.
I devised a home brew process following Rover SD1 Club local meeting discussions with Dave Horne and have done all eight injectors on two different cars including my current Twin Plenum Vitesse. The injectors are still going strong since 1998.
All the components needed for injector overhaul can be sourced from a local injection specialist or from Burlen Fuel Systems (see below).
First off, however, to best understand these bulletproof items it is useful to have some knowledge of how they operate for diagnostic purposes and to establish the nature of any fault condition.
Even more important is to identify and eliminate any other faults which might exist that can make it seem that an injector is at fault and thereby ensure money is not wasted in replacing perfectly good Fuel Injectors.

The Diagnostic Challenge Continues
This above article is one of fifteen or so presentations on the key components making up the Electronic Fuel Injection System fitted to Rover SD1 Vitesse and Vdp Efi.
Pulling all these components together is the Efi Operations, Test and Instruction Manual enabling Home Enthusiasts to better understand its Purpose, Function and Maintenance.

According to their service manuals Rover would have had us believe that the Fuel Injectors fitted to the Rover SD1 Efi cars are not a serviceable item. However, most people are aware that they can be cleaned which is an expensive process and a neat way for service outlets to make loads of money (£150 per set of 8) for just a few minutes work on each injector. Worse still, a set of new injectors may well cost as much as £450.
What isn’t so readily known is that the Rover SD1 Efi Injectors are very robust indeed, can be flushed out and cleaned in the home workshop and that the service parts are not at all expensive.
