I received the turbo C900 I've mentioned in a few places recently and it's
got a problem starting. The starter works fine to crank the engine, but it
sort of fires but sort of doesn't. I have checked the distributor, coil,
etc. and made sure all the wiring is in place and not broken, etc.
Last night I got thinking that it might be the fuel pump relay because if I
crank for about 10 seconds, let the key go, move back to off, then crank
again, it fires straight away.
Is it possible that the fuel pump relay is not kicking in to start to fuel
pump on the first attempt at starting? Looking at the schematics in my
Bentley manual, the fuel pump should start as soon as the key moves into the
'run' position on the earlier 900's which don't have the fully-pressurised
tank and single-stage fuel pump.
I know that on my 1985 900i the fuel pump runs for a bit then stops when the
key moves to 'start'. On the 1983 900S the pump starts and keeps going. It
could be a peculiarity of being a turbo-equipped C900 that's part of the key
with the newly-acquired car...
I'll try changing the fuel pump relay later on just in case it helps.
