My truck's fuel gauge quite working. Conventional wisdom says its the sender. Checking with some experts (includig "workallthetime"), I came to the conclusion that is the failure. Ordered up a unit from ebay (used but good) for about 1/6th the price of new. Pulled the bed of the truck (8 bed bolts- 4 taken out, 4 loosened), 2 wire connections and 3 small screws that hold the fuel inlet. Used the cherry picker (engine hoist) to pull the bed up enough to remove / replace the inlet/return/sender combo chevy uses.
Still don't work. DANG.
I checked the replacement unit 40-250 ohms with no discontinueties. Checked the wires in the plug. No ohms and no volts. Hmmm. Checked the removed sender. 40 to 250 ohms with no discontinueties. Uh-oh. Got advice to have a code checked / reset from Workallthetime. They found a code - above 98% high level. Being set all the time. The service guy was nice enough to print out the service decision tree for me. They also scanned and spent some time at no charge. While we were there, they had to cut a new key and had my son do the button pushing. He thought that was pretty cool.
So, I go home and go thru the tree. It points to a bad wire, bad connector or bad PCM. I had visualed the wire harness from the tank to the engine compartment and it looked good. Pulled the fuse center in the engine compartment thinking that I may find a loose connector.
This is what I found.
That was around 10 am. It's now 1:45 and I just got in from spending more qualtiy time under the hood with solder, shrink wrap, little pieces of wire and electrical tape. I had to set up an umbrella over the tools as the sun made them too hot to hold. The sun also started shrinking the shrink wrap.
Uggg.
And we have 2 cats! Gotta get some barn cats..
