Stian > Today I went out in the garage for the obligatory once-a-week start and warm-up of my DeLorean. It is stored during the winter time. At the same time I wanted to check the door lights etc. so I didn't start the car, but turned the key to "position 2", when I suddenly heard a loud buzz coming from the engine compartment. Its the frequency valve (FV) which is on the RH rocker cover ( opposite side to the cold start ). When you turn the key to position 2 the RPM relay powers up the fuel pump ( and FV) and primes the fuel system for starting. Chris S
