I have a weird problem with my 1987 260E (2.6L engine). Anyway,
everytime I go to start it, it would seem to have start, but I settle the
key to run position and it would shuts off. On the next try
its ok. What i mean is, suppose I walk to the car in the morninng
I put the key in, then turn it to the start position. The c
car would make that cranking noise and I can hear the engine
revved up and sounds like it has started. So? I turn the key
away from the start position to the run position. Let my hand
go off the key. And the engines shuts off. I have to start
it once more before the engine stays on. Or I would have
to step on the gas just when the engine is about to shut off
and by doing this the engine would continue running and
everything is fine. What kind of problem am I looking at?
Fuel pump relay has been replaced. In fact I have 3 or four spare
fuel pump relay and it does it to everyone of those. Is it
the fuel distributor unit? or maybe its idle control valve? any idea?
