Fuel pump may falter or fail; fuel pump relay was non-functional, replaced it; other fuses passed testing with meter; vehicle started, would not run more than a few minutes. New fuel filter. Guy at service station banged on gas tank, and it would start then run great for a minute, then will not restart. Ordering a replacement fuel pump. Bought this vehicle in 2005 about the time of gm recall 05027. In doing online trouble-shooting today, I discovered the 2001 gm recall 05027. Have had this problem several times. Fuel filter was last changed in july 2009. Complete failure when in motion, backing out of service station onto main street (us 64 bus), just inches from lane of travel (6.14.19).what could be worse than fuel pump failure at a busy intersection during lunch hour? Grateful it didn't catch fire, or get hit. As the service attendant tried to restart it, over and over, the relay in the ecu may have failed at that time. In the interim, my husband died. I replaced relay/fuses today 9/14/19, and vehicle started, but would not stay running. Another mechanic banged on fuel tank, it ran for a while, so he advised replacing pump, which is not rocket science after viewing youtube how-to videos. With the pump failing sporadically, and responding to the vibration of being banged, it seems like faulty wiring or connection problem, or that something is loose or not fully seated anymore. Lots of folks say the chevy 1500 is widely known for fuel supply problems. Gas gauge has not been accurate ever. When full, it may show empty when turning or hitting a slight bump in the road. (track by computing mpg and mileage, to determine range). In short distances, it swings full-> empty->full. Wiring diagram shows tiny fuse labeled prime, none there. Abs indicator lights up because sensor cable at right front tire may fail on left turn, or hard right turn, yet brakes are fine.

- What is wrong
- Certain trucks and sport utility vehicles were built with fuel module reservoir assemblies that contain fuel pump wires connectors may overheat under certain operating conditions.
- Risk
- If the ignition circuit wire is exposed, the fuel pump fuse will blow, disabling the fuel pump and causing an engine stall or no-start condition. 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 diagnostic routine. Fuel vapor and in some cases liquid fuel may leak out of the fuel tank through the hole in the connector body. Fuel leakage, in the presence of an ignition source, could result in a fire. Also if the ignition circuit or ground wire is exposed and shorts to the fuel level sender card wires, inaccurate fuel level readings may result.
- Remedy
- Dealers will remove the fuel tank, and remove the module reservoir assemblies from the tank, and install a new service kit free of charge. An interim letter to owners was mailed on may 25, 2005. The owners were re-notified on october 19, 2005, since parts are now availabe. Owners may contact chevrolet at 1‑800‑630‑2438 and gmc at 1‑866‑996‑9463.

Overheated fuel pump wiring
In a letter dated april 14, 2005, general motors (gm) notified odi that it had identified a defect related to motor vehicle safety in approximately 316,508 model year (my) 2000-01 1500 series chevrolet suburban and gmc yukon xl vehicles (recall 05v‑155).gm determined that some of these vehicles were equipped with fuel module reservoir assemblies (mras) that contain fuel pump wires and/or connectors that may overheat under certain operating conditions.according to gm, fuel pump wires that overheat may result in one or more conditions that present risks to motor vehicle safety:(1) fuel leakage from the mra pass-through connector if the overheating produces a hole in the plastic connector; (2) engine stall if wiring exposed by the overheating shorts to ground and causes the fuel pump fuse to blow; or (3) inaccurate fuel level readings if overheated wiring is shorted to the fuel level sender card.gm's analysis identified the cause of the overheated wiring as a high-resistance condition in the mra connector contacts due to fretting corrosion that may develop over time.gm determined that the corrosion is caused by movement between the contact surfaces and that such movement is primarily influenced by chassis and fuel tank virbration characteristics.gm's testing found that the fuel tank vibration characteristics of the recalled my 2000-01 1500-series vehicles were significantly greater than in other gm vehicles equipped with the same mra connectors.these vehicles had the highest rate of related fuel leak and stall complaints; and a recent survey conducted by gm found evidence of mra wiring over-heating in almost one-third of the 1500-series vehicles inspected. Other vehicles equipped with the subject mra connector and evaluated during this investigation include approximately 33,000 my 2000-01 2500-series sububran and yukon xl vehicles, which fall within the scope of ea04-026, and peer populations of short wheelbase yukon and tahoe utility vehicles and full-size silverado and sierra pickup trucks. These vehicles are not included in recall 05v‑155 for the following reasons:(1) these vehicles are equipped with fuel tanks with significantly less vibration at the mra interface than the recalled vehicles; (2) the potential for fuel leakage is substantially lower in the pickup trucks and short-wheelbase utility vehicles due to differences in fuel tank configuration and no incidents of fuel leakage due to overheated wiring were verified in these vehicles; (3) there there have been only three potentially related complaints of fuel leakage associated with the overheated wiring condition in the 2500-series long-wheelbase utility vehicles; and (4) no evidence of overheated wiring was found in the 2500-series suburban and yukon xl vehicles and pickup trucks inspected by gm in its vehicle survey efforts and the rate found in the short-wheelbase utilities was lower than the recalled vehicles by an order of magnitude. Odi will continue to monitor the experience in the 2500 series my 2000-01 long-wheelbase utility vehicles.the closing of this investigation does not constitute a finding by the federal safety agency that no safety-related defect exists for the 2500 series vehicles.the agency reserves the right to take further action if warranted by a change in circumstances.

Overheated fuel pump wiring
The fuel pump wiring and connector may overheat and melt a hole in the top of the fuel pump module.possible consequences include fuel tank leakage and engine stall with no restart.fourteen of the 20 complaints to odi allege fuel tank leakage, including one that reported that a fire department was called to the scene after a pool of gasoline was discovered beneath the vehicle.most of the odi complaints report incidents that occurred within the past year. According to gm, fuel leakage can occur in the subject vehicles if the heat is sufficient to melt a hole in the plastic connector large enough for liquid fuel to flow through.on-board emissions diagnostics may detect holes that are approximately 0.040 inches or more and set a service engine soon warning light.the connector position in the subject vehicles is below the fuel level when the tank is full.while gm does not know how much fuel could leak from a tank with a melted fuel pump connector, several consumers have reported significant leak events.engine stall can occur if:(1) a short occurs in the pump wiring (bare wire exposed by melted insulation shorts against a ground or ground wire) and the fuel pump relay fuse is blown; or (2) the vehicle runs out of fuel due to an inaccurate fuel gauge reading resulting from an electrical short between the fuel pump wiring and the level sensor wiring. Gm's analysis of five assemblies returned from incident vehicles determined that the condition is caused by elevated resistance/ arcing at the mra undercover b cavity terminal of the four-way 150 metri-pak connector.gm attributes the high resistance and arcing to a depressed contact arm at the 150 metri-pak b cavity female terminal.gm is continuing its investigation to complete its root cause analysis. Modular reservoir assemblies using the 150 metri-pak connectors were used by gm in several million c/k-series sport utility vehicles and pickup trucks from my 1997 through 2002, when gm released a metal mra cover and a 280 metri-pak connector in the subject vehicles.during pe04-042, odi collected information from gm concerning my 2000-2002 c/k SUV's and pickup trucks.the subject vehicles comprise approximately 9 percent of production for those vehicles and about 39 percent of complaints to gm. This investigation has been upgraded to an engineering analysis to further assess the scope, frequency, and safety consequences of the alleged defect in gm c/k-series vehicles.

Most recent owner complaints, unedited.
The bolts that hold the exhaust manifolds down are breaking off at the heads and causing exhaust leaks. Which are in turn causing my catalytic converters fail prematurely. I hope gm fixes this massive problem with there ls v8 engines!

First incident: veh. Would crank but not start. Turned out to be fuel delivery fuse. Replaced, and ran fine for several weeks. Second incident: driving at approx. 55 MPH, vehicle lost power, started sputtering as if out of gas although it was 1/4 full. Unable to exceed 25 MPH due to little/no power. Was towed to autoparts store, cleared codes, veh ran fine for about 2 days, then lost power. Towed home. Looked up info on internet, found recalls for fuel pump. Called local chevy dealership, inquired about recall, was told that recall was only on half-ton suburbans and since mine is 3/4 ton, it was not covered by recall. I replaced fuel module myself and discovered the covering of the wires inside the fuel module assembly had melted, allowing the bare wires to rub against each other, shorting out the fuel delivery system (which likely caused the blown fuse to begin with). I am very upset that my suburban is not covered by the recall, even though it is virtually the same system as what is in the the 1/2 ton suburbans, and the same problem exists (as evidenced by not only my own experience, but many others' experiences as well). I am extremely disturbed that under the right circumstances, fuel vapors, plus spark of bare wires touching, could ignite, causing fire and/or explosion. Possibly with my family of six in the vehicle.

I have a 2001 chevy suburban k2500, it takes me 45 minutes to fill up the gas tank, I believe the air does not escape from the gas tank and it causes it to overflow when filling and may cause fire if unattended since when you press the gas pump to pump faster it overflows and leaks on the exhaust pipe and could cause fire, also gasoline might do harm to environment while overflowing, so, please help, its winter here where we live and 45 minutes at the gas pump is really something, thank you-valentin
Gm currently has a recall for wiring on the fuel system for 2001 suburbans. My fuel pump assembly was replaced recently due to this same issue. The VIN number of my suburban was not covered, however, the problem was that as described by the recall notice. The repair shop contacted the local dealership, and the dealership would not cover the repair as not an approve recall VIN for my suburban. Based on what is published, this repair appear to be the same thing. Would like reimbursement for this item.
