Thanks everyone for your advice and also your support which is appreciated.
Car has about 125k on the clock.
I have now also:
- jumped contacts 30 and 87 on the fuel pump relay - no response in any key position or while cranking. Have never been able to make the fuel pump make any kind of noise.
- removed the fuel line from the fuel pressure regulator. No gas in line and doesn't appear like there has been any for some time. Dry and no strong gas smell.
- removed the mass flow air meter and 'rotated' the vane inside a bunch of times to see if that helps.
I suspect a bad fuel pump or some form of a bad signal which would ultimately power the fuel pump. I could test by swapping suspect pump with the fuel pump in my 'good' E30 - but that seems messy and a lot of work. Is it?
Is there an easy way to directly power the fuel pump?
Complication - I don't have any sort of voltmeter or multi-meter. A 12v DC power supply I can kludge together.
Thanks again very much Comrades.
