Some of you will remember that the new owners of our Clasco experienced a no start issue following refueling south of Denver last summer on their way back to Alaska. They reverted to the carb and made the rest of the trip. At the time there was much speculation on this forum as to the root cause issue. Many speculated that it might have been too much heat for the throttle body mounted ECM, others that the high pressure fuel,pump inside the fuel command center might be bad, etc.
We are in Quartzite, AZ for the day and it turns out the new owners are as well and found us. It turns out the issue was an intermittent failure of a connection inside the main factory wire harness plug. He said he called the factory when they got back to AK and asked the FITECH guys what the problem might be with the throttle body. They had him reinstall the FITECH throttle body and it fired right up so the mystery remained. Later he said they experienced another failure after fueling. That time he rooted around under the hood and while moving things around heard a click. The FITECH fired right up again. He then could replicate the issue by squeezing that connector, one wire crimp was faulty inside the plug. No issues since.
Who would ever have thought a factory crimp could fail intermittently inside a factory plug.........
