When cold (left over the night) my 380SE is very hard to start. It takes a lot of cranking and when it fires it does so only very poorly (requiring full trottle) for the first half minute or so.
When warm (that is, have been standing for an hour or so) it starts with the slightest touch of the starter and runs smoothly (I love that sound :-).
I'm guessing that the warm-up regulator may be at fault. Am I on the right track? Both the voltage to the regulator and the coil resistance within are within specs, though. Any other things I can check the warm-up regulator for?
Other probable casues of the hard starting? I've verified that there is sparks; there is gas spraying out the injectors; there is compression; and the cold-start valve is working for the specified couple of seconds at the current temperature (approx. +5C).
This problem appeared suddenly (would not start one cold February morning but ran fine the day before). The car has 450' km below the belt.
Other likely causes?
Thanks, pej
