[DML] Re: HOT or COLD START PROBLEM?

["David Teitelbaum" <jtrealty@xxxxxxxxxxxxx>]

You *may* have a bad thermo-time switch but you definately have a
problem with your "Rest Pressure". That is the pressure that is held
for a while to restart a warm engine. It is kept up by the accumulator
but it can be lost quickly if you have a bad fuel pump check valve or
a leaky Primary Pressure Regulator. I would go ahead and replace the
accumulator. If you still have the problem then get a new check valve
and replace the "O" rings in the pressure regulator. Be careful not to
change the setting. That should fix your hot-start problem. I would
not think the thermo-time switch is a problem but it is easy to test.
Doing the plug-swap confirmed the problem with the rest pressure.
Generaly if the thermo-time switch is a problem it makes the car hard
to start when cold but I guess it can fail "on" where it would make
the motor over-rich when starting warm-hot. Easy test. On a warm motor
pull the plug to the cold start valve and see if there is any power
when warm-hot and cranking.
