You know, this is one that really should have been a safety recall by GM... but I am sure it was swept under the rug. I thought my fuel pump had died but realized like others that not everything was working. The inquisitive type and electronics tech in me embarked on the troubleshooting journey. Low and behold, I found the same 4 wire connector behind the battery and same fried connections. I attempted to clean the contacts and used a silicone dielectric compound to try to reduce any oxidation that may result from the heat of the connectors. So much for great ideas!
On a few occasions now, all power has gone while drivng at night and believe me, it will get your attention quick! It got two of my daughters attention especially when they were driving it.
Here's the ammo.... I went to a salvage in OKC, OK owned by some longtime friends, they told me to help myself to find another connector to replace mine. Guess what Inspector Gadget found????
You guessed it... nearly every one I found with that darn connector had been extremely hot and melted the plastic inside the connector (the same thing that caused the loss of power in mine). I literally went thru 6 vans before I found a good one! I just wonder how many of those vans were there because of the power problem???? HMMM?
So, unscientifically, there is a problem with those connectors and I just hope that nobody is hurt because of the great potential for failure in the BAD DESIGN!POWER FAILURE!
