Starting blues..

[castillo@caries.dental.mu.edu (Dr. Manuel Castillo)]

I have a 5kw with 108K mi. Since the beginning of winter I have experienced
starting problems. The car always start ,but not after several attempts.
This is specially true when the car is cold. If I turn the starter with or
without depressing the accelerator, the engine will start for about three
seconds and then die. After that the engine will crank without starting.
Probably after six or seven attempts the engine will start with ease.
Someone had mentioned a bad cold start switch or perhaps a bad injector.
This weekend I tied disconecting the electrical lead to the auxillary
injector. This was the connector closest to the injector, but no luck. It
didn't start. Is there someone out there with some idea on how to cure my
starting blues.

Thanks, 
Manuel
