Problem Solving:
The most common problems affecting TR6s these days is their low usage and the periods that they spend in storage. Even in dry garages the inside the inside of the fuel tank may corrode shedding fine iron sediment as soon as the car is moved. Once corrosion has started it may be more expensive to cure/eradicate than the cost of a new tank.
If a problem is suspected, the tank may have to be flushed by filling and draining several times. Another common ailment is caused by water, which will sit at the bottom of the tank, under the fuel, and cause corrosion. This may actually get as far as the engine when it will cause havoc to a metering unit or injector.
The P.I. system may need pressure checking at several points to identify a problem. The pressure relief valve (PRV) should ‘blow’ at 105 - 110 PSI, and there should be over 90 PSI at the metering unit outlets. Injectors pop at 45-55 PSI. Rebuilt injectors are tested to perform within this pressure window, and spray an even cone of fuel.
