The experience of many Rover SD1 Efi owners suffering faults on their fuel injection system is, often, expensive spares have been purchased to try and effect a cure when, in fact, a methodical approach to analysis and testing might have identified simple faults, easily cured.
Early versions of electronic fuel injection systems as fitted to the Rover SD1 were prone to simple fault conditions, often impossible to diagnose without specific guidance. Dealers had the information, but hardly ever see these cars nowadays and, anyway, have dissipated their knowledge of them. Consequently the Efi system can become maladjusted and troublesome to a current owner who now has nowhere local to turn for help. This has led people to form opinions that the system is inherently unreliable. Nothing is farther from the truth, it being the lack of proper knowledge and maintenance that has contributed to that current perception.
Drawing on my experience since '93 of Rover SD1 Vitesse and Vdp Efi ownership, I compiled a technical manual (using data from the "Range Rover Efi" version) for the Lucas Type "L" Electronic Fuel Injection System fitted to the 3528cc V8 Engine installed in '82-6 Rover SD1 Efi cars. Specific references to Range Rover components, where they differ from the Rover SD1, have been eliminated and replaced with descriptions of the alternate SD1 components, locations and wiring. In addition, errors that appeared in the original material have been corrected and verified. I present it in a style more suited to the average (DIY) SD1 Efi owner/enthusiast as opposed to the original material which was aimed at experienced dealership motor technicians. The technical digest of the Efi system and its components are clear and unambiguous and consists of 18 doubled sided A4 pages ideal for laminating to prevent soiling in a workshop environment.
It was originally prepared for personal use but the Rover SD1 Efi community said they were keen to buy it so I made it available at modest cost in 2004. Sadly, a boy racer with bad friends removed my creditation from each page and blatently made it available under false authorship. Even when rumbled they refused to remove their falsehoods but time passes and overcome with shame the very nice people have since withdrawn it. Hence it is available again, here! Interested?
