Check here for an introduction to Lorrie Van Haul:
Lorrie and I have come to the end of our rope. Am at a total loss as to what to do next.
Permit me to explain the situation:
Lorrie has been fitted with an HEI System consisting of a NOS Mopar Electronic Distributor, a Ford E-Coil, an LX301 Control Module, and a set of NGK ZFR5N Spark Plugs gapped to 0.045".
Right after the installation, she was running wonderfully until the FIRST cold day of November, 2012 when for some unknown reason, she quite starting.
She was running just the day before, was out and about, came home and shut her MIGHTY 225 Slant Six Engine down.
The next morning the temperature was in the high 20s. Went out to run an errand, and Lorrie's Engine would not start.
There was other work that had to be done, and so Lorrie sat from early November till a couple of weeks ago, when the other work was finished, and the focus once again turned to Lorrie Van Haul.
A NEW set of NGK ZFR5N Spark Plugs gapped to 0.045" were installed, and Lorrie started right up!
Was so glad to have that happen and was thinking that maybe the FIRST set of NGKs was the problem. But since her restart a couple of weeks ago, she has once again failed to start whenever the weather is cool. She WILL start SOMETIMES when the ambient temperature is approaching 70 degrees, but she won't start all the time. Whatever is wrong is intermittent.
Have gone back over everything multiple times. Everything seems to be in order.
One thing though: A while back, Lorrie was given a NEW Voltage Regulator which turned out to be delivering over 18 Volts to the Battery. When that was noticed, the VR was changed out for another NEW VR. And it subsequently was found to be putting out well over 16 Volts to the Battery. It is presently the VR that is in Lorrie.
So my question at this time is: Could the Voltage Regulators putting the 18 and 16 Volts, instead of the 14.6 Volts that is nominal for this application have damaged the LX301 Control Module to where it will sometimes work and sometime won't work?
And is there a way to check the LX301 Control Module?
Am asking for help, and will supply complete answers to any questions that might be asked.
Thanks in advance for any assistance.
