I have the campaign with the vin breakpoints I'll paste it. More than likely you would be getting notices out the wazoo if yours was involved. If its close to 100k better be thinking about replacing the pump anyway. The fuel gauge thing is caused by the wipers on the level sensor in the tank wearing off. Very common on a lot of GM vehic's

A couple other things that cause that problem are the fuel pressure reg on the ingectors failing and letting fuel bleed off into the intake while the engine is off. Another easy thing to check and clean is the throttle bore. They get "coaked" up with goo and it throws off the minimum air rate causeing hard starts without having to press on the accell Take the snorkle off and spray it down, open the throttle and wipe out the bore. We have seen that fix a few vehicles with that problem. (my luck is never that good though )

Oh, EGR's will not cause a hard start without other driveability issues....... Dont make your problems any worse!



Subject: Product Safety - Fuel Module Reservoir Assembly #05027A - (03/10/2006)



Models: 2000-2001 CHEVROLET 1500 SERIES SUBURBAN

2000-2001 GMC 1500 SERIES YUKON XL




--------------------------------------------------------------------------------

THE SERVICE PROCEDURE IN THIS BULLETIN HAS BEEN REVISED TO INCLUDE THE USE OF TOOL J 41413-300, EVAP CAP/PLUG KIT. PLEASE REVIEW THE SERVICE PROCEDURE IMMEDIATELY. DISCARD ALL COPIES OF BULLETIN 05027 ISSUED OCTOBER 2005.


--------------------------------------------------------------------------------

Condition
General Motors has decided that a defect, which relates to motor vehicle safety, exists in certain 2000-2001 Chevrolet 1500 Series Suburban and GMC 1500 Series Yukon XL vehicles. Some of these 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 of the following 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 the ignition circuit or ground wire is exposed and shorts to the fuel level sender card wires, inaccurate fuel level readings may result; 3) if sufficient heat is conducted to the pass-through connector, a hole in the connector may result, which may cause a Service Engine Soon light to be illuminated during the emission system diagnostics routine. Fuel vapor, and in some cases liquid fuel, may leak out of the fuel tank through the hole in the connector body. If a sufficient amount of fuel were to leak out and if an ignition source were present, a vehicle fire could occur.

Correction
Dealers are to remove the fuel tank, remove the fuel module reservoir assembly, and install a new service kit. The service kit includes a new pass-through connector, wiring harness for the fuel pump and fuel sender card.
