Hi All,
Happy New Year and hoping we all have a great and fault free 2023. But alas, mine is starting with a niggle.
I'm after some help for my 1985 930 Turbo, it is modified, but am hoping the issue described below is more of an original type!
During the autumn, the car started to stall when cold. The car starts on the first turn of the key and fully cold, but gets harder to start the longer the engine has run / slightly warmer. The first few times I could get it started and get where I needed to be with a few embarrassing stalls along the way. Its steadily got worse. The stall is an instantaneous 'stop' rather than a a gradual stall I would normally associate with fuel starvation.
So over the last month, I have checked / tried the the following:
-checked all the vacuum hoses and replaced any of concern.
-fuel pumps are whining on ignition and when stalled. I am assuming that they are OK.
-CDI should be OK as its a newish Retrofit unit.
-new fuel pump relay
-checked the AAV with the notch showing at cold and then closed when 12v is applied after a few mins.
-WUR has just recently been rebuilt, so assuming this is not the issue.
Any ideas of where to look next? Do I need to investigate the fuel pumps any more? Could it be anything to do with the engine cut-off relay in the engine compartment?
Thanks in advance
Si
