Hi Guy's

I have an old 300SE 1989 that wont start, I know it's a fuel issue because it will fire if you throw some petrol down it's throat, it looks as though the pump is not working as I can't get fuel through the pipes, can you advise:

1. Is there a relay and where is it? Can it be tested (shorted)

2. The car is reversed up to a fence so I can't see underneath properly, is the pump up under the rear axle.

3. Has anyone got a suitable pump just in case?

Thanks


Tom
