GMC Yukon XL: Electrical
Affects GMC Yukon XL · 2000–2001 — about 9K vehicles.
The hazard
Certain vehicles were built with fuel module reservoir assemblies that contain fuel pump wires and/or connectors that may overheat under certain operating conditions. Fuel pump wires that overheat may become exposed and result in one or more conditions; 1) If the ignition circuit wire is exposed and shorts to ground, the fuel pump fuse will blow, disabling the fuel pump and causing an engine stall or no-start condition. 2) If sufficient heat is conducted to the pass-through connector, a hole in the connector may result, which may cause the Service Engine Soon light to be illuminated during the emission system diagnostics routine. Fuel vapour (and in some limited cases liquid fuel) may leak out of the fuel tank through the hole in the connector body. 3) If the ignition circuit or ground wire is exposed and shorts to the fuel level sender card wires, inaccurate fuel level readings may result. Correction: Dealers will affect repairs.
