Does anyone know if vaccum is req'd to start a 240d? Does the vacuum fuel shut off use the vac to switch off the fuel or to enable fuel flow? My 240 has just developed a reluctance to start first thing. Not temperature related, just hard on first start, tunrs over well, appears to have fuel at IP, just doesnt fire for ages. Wondering if the low vac at idle (10) is a factor....

Once it has been started once, it's easy to start for the rest of the day.....
