RE: [DML] Re: Can someone explain this? (distributor positioning)


Again I think you need to KNOW about the CPR instead of guessing about it. I 
would suggest getting a CIS fuel pressure test set (John Hervey will loan 
you his.) and then you will KNOW if the CPR is good or bad. Of course you 
could just replace it with a new one, but having the CIS test set will also 
let you have a look at such things as the dead-head pressure of the fuel 
pump, control pressures, and how well the fuel system retains pressure when 
shut down. (Tests the accumulator and check valve in fuel pump.)

A dead short inside the CPR would cause the meltng you describe. Take an 
ohmmeter and check out the heater. It may be shorted out. If it is then just 
get a new CPR. Otherwise get a CIS fuel pressure test set and find out what 
is actually going on in your car in terms of primary and control pressure 
when the car is cold and as it warms up.

Not having the heater wires connected to the CPR would just mean it will 
take longer to warm up. What does that mean to your problem? Well it means 
your car will run RICH (ah ha!) until the motor is warm enough to deflect 
the bi-metal strip inside the CPR. Until that happens your control pressure 
will stay low and the car will run RICH, RICH, RICH!

In your case it is possible that the strip is jammed inside the CPR keeping 
the control pressure from ever rising.

So you may be onto at least part of your problem with the CPR. Ohm out the 
heater element and get a new CPR if it is bad. If that checks out okay 
(which it probably won't if the wires are burned) then cheheck it out 
furtehr with a CIS test set, or just write a check for a new CPR.

Before replacing the CPR make sure you see heater voltage on the 
(disconnected) connector when starting the car COLD. With the wires burned 
the way they are taht may not be working anymore.

Good luck.
