[W126 Coupe] 1- doesn't start in cold 2 - oil pressure strange

[Sharan Bains]

Hi James,

Not sure on the part no for the connector, but if you give MB delaership 
parts a call with your chassis number and they should be able to pull up the 
diagram of the oil sender arrangement. It should only cost a couple of 
dollars.

The loom going from sender to dash usually has a second two pin connector 
plug in-line, where it runs up near the wiper motor to the fusebox. Check 
that the conenctions are intact at that plug too.
