This may sound trivial, but I'm getting nervous! The car has always started
within 1 second, hot or cold. I would guess on the first revolution after
engaging the starter. Lately, it cranks for a couple of seconds before
starting. It runs fine once it has started. It's got 180K miles on the
odometer. Plugs haven't been changed for years! Fuel pump relay was new
about 8 months ago.
Any ideas? Fuel filter? Plugs? I'm paranoid?
Thanks in advance.
Hi John, my 89 300e started doing the same thing earlier this summer,
it has not gotten worse. I've changed plugs etc etc to no avail... whereas
it used to start with a turn or two, it now takes 4 or 5 sec cranking and
once it starts everything is fine. Moreover, and this may be fortuitous, this
is the first summer that the car apparently has suffered vapour lock - ie
it took over 5 min or thereabouts of cranking befor starting/sputtering and
then continuing fine. the only thing I've not checked so far is the fuel
best wishes, guenter
You are right about vapor lock when engine is hot. In your case it is most
likely to be the fuel accumulator that is leaking... easily checked by
pulling out the rubber hose and if fuel keeps dripping out, it is bad.
I suspect the same problem with the 420SEL... usually occurs when engine is
hot... very hard start after 10 minutes (tThis however depends on how bad
the accumulator is leaking)... In cold start, takes a bit longer to start.
