Coachi: I will follow the service manual to the letter. It involves a lot; each bank has to be tested separately. My gauge is the exact one they use. Since my warm starting problem is intermittent, I don't even know if I will be able to find the answer to my problem......I am considering waiting for the problem to be more frequent.
The procedure appears to be the same, and is described in the service manuals for the 308, 328, TR, and BBi (actually 400i), etc. |

when you have successfully completed the testing procedure, would you be kjind enough to describe it to us? |

Thanks Steve,
You gave me a thought. The "most accessible fitting..." would be one found beneath the car. I do have a car lift, so that shouldn't be a problem. Maybe at the fuel pump; that way I can check the no-return check valve. |

You just need to be prepared that some fair amount of fuel will squirt out when you crack open the first fitting -- usually placing a moderate rag over/around the fitting as you crack it open is sufficient. I'd guess that the accumulator holds about 1/2 ~ 3/4 cup maximum so it's not a huge amount, but still it's enough that you do need to be careful and not spray/drip it about. I usually crack open the most accessable fitting to relieve the pressure in the primary supply lines (even if I'm not working on that component) just for the best chance to not make a mess.
PS Wear safety eye glasses whenever working on a pressurized fuel systems. |

I will soon be testing the fuel system on my BBi, using the gauge shown in the manual. In reading up on it, all the tests with this gauge, are done on a cold engine, with the ignition on, and the pump, running.
My question is how do I release the initial fuel pressure in the lines without spilling fuel on the engine? The gauge is connected from the fuel line going between the distributor and the warm-up regulator. I know that on an electronic injector, one shorts out an injector and the pressure is released by dumping gas into the cylinder. But how is this done on a mechanical fuel system?
Help me before I burn my engine!!!!!!!!
