Well, I was able to purchase the AC Delco hose with the 1" fuel check valve (see above) from a third-party seller on Amazon. I've also seen it go up for sale on Ebay. Meanwhile, my daughter's been burning 91-octane no-alcohol fuel and getting tired of paying for it. So today we attacked the...

Immediately after a year? Or immediately immediately, on the first tank? Amazon has a listing for the hose, but it is unavailable. Many other GM parts houses also list it, but as unavailable. Thanks for your reply.

My daughter's '06 KJ is exhibiting the fuel burp problem on every fill-up. The pump is late to shut off and gas spills from the fuel filler. I have read the threads here on the matter, including the excellent guide for inserting a check valve in the filler hose. This procedure calls for...

I bought a replacement harness 56050844AF from Ebay by making an offer on a listed auction. The harness is new old-stock. It is a very big harness with a lot of connectors. My mechanic said he wanted to see the harness and the car before he would estimate the cost to replace it. In the end...

My daughter's '06 KJ 3.7L has similar symptoms (ABS/ESC/BAS lights, no speedo), but it has rodent damage to some wires, near the firewall under the brake master cylinder. Similar codes too, I think an U1120 and a P0501. I just bought a new harness (New, old stock) off Ebay for 2006/2007 KJ's...

My daughter's 2006 KJ ( 3.7l gas ) has a non functioning speedometer and ABS, brake, and ESC/BAS lights on. Mice have chewed wires in the harness near the firewall penetration under the brake master cylinder. I suspect the best repair is to just replace the harness. Can you help me identify...

I worked with my daughter on her 2006 KJ. The speedometer isn't working and ESC/BAS/ABS lights are on. Before she bought the car, it was in barn storage for a few years. Apparently mice got to the wiring harness under the brake booster. There are two broken wires - and the other ends aren't...

Thanks for the tips. I replaced her battery terminals yesterday (because her ground connection was poor), so I spent some time in that area. I also reseated all four connectors to the PCM, spraying each one with contact cleaner before re-connecting. I see a couple of broken wire stubs in the...

My daughter just bought a 2006 KJ that has a dead speedometer, odometer that doesn't change, and has ABS and ESP lights on. Could a bad wheel speed sensor cause all this? It also has CEL and a few DTC codes. U1120, P0499, P0501, and P0700. The engine runs fine. The seller said he just took...

I drive an 06 XK, and my daughter just bought an 06 KJ to replace her 04 KJ with a failing engine. I support them all, with a moderate degree of mechanic knowledge, ability, and courage. I rely heavily on forums and YouTube. I'll be posting some questions here I'm sure. We're in Minnesota...

For my '06 Jeep Commander, I had to add a PID to Torque Pro to read Transmission Fluid Temp. I found the PID info in a Commander forum.

Some shops don't want to install used parts or warranty work on an old car. They miss out on their customary parts markup. They burn mechanics time with a lower rate of return. They have plenty of high paying customers and can afford to turn down work. Look for another shop, a part-time...

Sure seems to be a common problem. It's broken on my daughter's KJ also. I found this video on Youtube.
