2000 GMC Yukon XL: wrong fuel gauge reading

Filed Jul 24, 2006 · Fuel system · 83,000 miles · NJ

Dt*: the contact stated the fuel gauge readings were inaccurate. The dealer replaced the fuel pump which corrected the problem. There is a the federal safety agency recall # 05v155000, concerning the fuel pump. The VIN was not included in the recall. Updated 8/14/2006 - the fuel pump wiring melted inside the fuel tank.

Our gas gauge on our 2000 gmc yukon completely quit working. Took it in thinking it was an electrical problem and found out the fuel pump was broken. The problem that cost us a lot of money was that the fuel pump is located inside the gas tank and they had to replace the whole gas tank to fix the problem. First, why would this happen on a car this new with only around 50,000 miles and second, why put the fuel pump inside the gas tank so that it is so expensive to fix?

We are affected by the recent recall concerning the wiring harness for the fuel sending unit and are waiting for the new harness parts to arrive. However, about the same time we began having trouble with that, we also began to have problems with a sticking accelerator. After starting and placing the vehicle in gear, the throttle sticks and is obviously a mechanical problem rather than a lubrication issue. Once the vehicle begins to roll, the problem goes away. We ahev lived with this for some time and have recently driven two other gmc products (2001 gmc 1500 yukon xl and a 2001 chevy 1500 pickup), they too had the same problem. I am quite certain this is going to become a recall event due to the fact that with the sticking of the accelerator, the vehicle often lurches forward after enough pressure has been exerted. Please let me know what the status of this problem is. Thank you, don titus 817‑705‑1064

Noticed on several occasions that vehicle seemed to be leaking fuel when parked and turned off. Most recent case occurred shortly after refueling. Dealer diagnosed as a "cracked fuel sending unit". Apparently this allows fuel to be spewed out of the tank when parked. Dealer indicated that it wasn't covered by warranty due to mileage. Co-worker discussed almost identical problem with his yukon xl (except his spewed more fuel into his garage and need to be cleaned-up by hazmat team). This appears to be more than a random occurrence of a problem that has significant safety and environmental implications. I believe further investigation (by the federal safety agency and general motors) is warranted.

I own a 2000 gmc yukon xl. Over the past few months, I have had a problem with the vehicle continually blowing a fuse (ECM b fuse). Upon my own research into the circuitry, I determined the likely problem was the fuel pump. I replaced the fuel pump and upon removing and inspecting the old component, I discovered the hot wire (gray wire) which operates the pump motor had been hot enough to melt the insulation off the wire. Moreover, this hot wire had melted into one of the wires of the fuel level sending unit, which is a ground circuit. The problem I would like to bring to light here is that the fuel pump unit is inside the fuel tank. When this hot wire came into contact with the other wire, I assume there was a spark, or the potential for one. Why didn't my vehicle explode? I know there are thousands of these vehicles on the road, but I have not heard of any such explosions. I do know of another gm vehicle that had the same problem of exposed wires in the fuel tank. Please advise me of the danger level should this happen again. Thank you.
