Re: No Fuel to injectors

["content22207" <brobertson@xxxx>]

You didn't by chance replace the small diameter line from accumulator
to filter with something larger? That small diameter line is what
creates high fuel pressure, not the pump itself (is not 75 PSI from
the tank). Kind of like putting your finger over end of a garden hose.

See Message #32067. Sounds definitely as though you aren't "cracking"
the fuel injectors. Need minimum 50-51 PSI to start spraying. If
you're SURE everything from fuel distributor forward is factory spec,
may need to adjust fuel mixture screw. You may not have touched, but
are you sure no one else has? Note fuel mixture is set with car
running -- NO VACUUM LEAKS! If you've got an injector out, plug its
port in head -- 1/4" vacuum leak otherwise. Make sure line feeding
idle speed motor from under fuel distributor is tight -- 3/4" vacuum leak.

BTW: are you sure control pressure regulator is plumbed correctly?
Supply is from bottom of fuel distrubutor, same side as tank return
line, port closest to rear of car. Line out of course goes to top of
fuel distributor. This is a wonderfully clear pic:

Note that lines in this pic cross out of sight when attached to
control pressure regulator itself -- line in is closest to rear of
vehicle, line out closest to tank.
