Ive finally got the m42 conversion in and cant get it to start, i have good spark and fuel up to the pipes for injectors but no fuel at injectors.
Does any one know which pipe is the fuel feed for the injectors at the maniflod, the black metal pipe or the silver one, will it do any harm if i just swap them over and try it?
Is there any other things that i should check as the engine has had a full rebuild(rings, shells chain and tensioners etc etc) and i dont want to keep cranking it for ages,
Have looked on wiki but cant seem to find the answers
Any help most appreciated

The fuel return pipe should be connected to the fuel pressure regulator.

This section of the wiki tells you how to test the system... http://www.e30zone.net/e30zonewiki/inde ... _to_Engine
