I am reading from TSD4737 and it’s unclear from where to take a pressure reading. I’m sure I can rig up a pressure gauge. Where to measure from?What fuel pressure have you?
Connect the guage to the pipe that goes to the cold start injector, should have 6bar.
I will do that. I’ll let you know! Thank you!
It is inside engine comparement, right side, near engine ECU unit, if your car is fitted with inertia switch. I'm not sure if 2xxxx cars have it.Both are ok. B5 is labeled “fuel injection” and has power to it with the key off.
What about the inertia switch which can isolate the fuel pump. Where is that?
Thank you kind sirs.

I have checked fuses. They are ok. When I direct 12 volts to the pump it runs, but then no start. And when I power up the pump, the engine won’t turn over. I have to momentarily disconnect power to the pump to get it to turn over. All this and it won’t start. It will run if I put a little gas in the air intake. For a few seconds…A few days ago it ran, albeit not especially well. And now it runs only when provided some additional gas poured in the air intake. Pump not operating with just the key on or cranking.IMHO it is for Ignition. Fuel pump is F2 B5 in 2xxxx cars?
