Previous owner explained the truck was on its third fuel pump. I have to demand that some action be taken before it is too late for someone. Hope this cures your problem. The last two times it went out I had it replaced by a chevy dealer in tampa. It does have battery power at relay. Now the fuel pump relay keeps burning up on me. The purpose of this video is to collect enough evidence to justify getting to the fuel pump for further diagnosis.
Every single pump is 100% tested throughout the entire manufacturing process for worry free, out of the box performance. I'm a quality control inspector for aircraft and this would have grounded the entire series of that particular aircraft. Depending on the month of 03 your truck was built it may still have the fuel filter on the driverside frame rail back were the transmission crossmember bolts to the frame. If the relay socket terminals are discolored from heat that must be replaced as well. To reduce risk of contaminating the replacement pump, Delphi recommends cleaning the fuel tank before installing a new pump. Another thing that bothers me is the volt meter only reads about 12. Checked the frame ground for the fuel pump and it is seems in good order.
After having all this work done, the last fuel pump only worked for about 6 months before it went out again. S I dont know if the pcm might be on the way out with the miles it has on it? My vehicle is the z-71 version of the Chevrolet 1500 pickup truck. Any water or debris can cause major injector damage. I have been viewing the complaints located on your website and feel that there is a significant pupose for recalling these vehicles. Pump failed on me in on an extremely hot day over 100 f degrees. Let the stuff soak in and work. To keep it in peak form, you need respond to any sudden shift in performance, which is how you know that sudden jolting on acceleration points directly to the need for a new Chevrolet Silverado 1500 fuel pump from AutoZone.
The contact is aware of the safety risk involved. The Fuel Control Relay is the left relay and The Fuel Pump Relay is the right. If air was introduced there would have been an explosion. Replaced the fuel pump with the same results. Other Category problem 1996 Chevy Truck V8 Two Wheel Drive Automatic 332k miles I just lost my fuel pump and put a new one in and it works fine but my truck wont satr ive checked for fuel pressure and spark and have plenty of both.
We're not done with the fuel system in this truck just yet - stay tuned for more. Is the pressure at the rail zero or does it have a low reading. If the vehicle starts, then replace them as a pair. I feel that the first sign of this problem is that the gas gauge will start to malfunction, which leaves you guessing at the amount of gas in the tank. To test these relays, swap them and then try to start the vehicle, or blow the horn. Fragments from the pump traveled to the filter, somehow made it past the filter and ruined the fuel pressure regulator. Notes: Fuel Pump and Sender Assembly -- Fuel tank contamination is the leading cause of premature fuel pump failure.
This is inside the fuel tank surrounded by fumes and fuel. If the horn blows then use that relay for the pump and you may at least drive the vehicle where needed! I pulled this off the net but it does sound… Under the driver's side cabin door. Problem came back when consumer noticed vehicle stalling and not starting. Thank you for using FixYa! The plastic insulation caused the wires to over heat and it burned down to the fuel tank. Three months later failed and the sender kit was replaced along with fuel pump and melted wires were found inside the tank.
Posted on Apr 27, 2009 It's located in the fuse panel under the hood of the vehicle in the engine compartment. The wires were too small a gauge for the load. If we wait until someone becomes involved in an accident, that would seem senseless that possibly someones life would have to end before this situation be taken seriously. Imagine the hazard potential had it died at highway speeds. This could have been a deadly experience for myself and that of anyone that could have been in the vehicle with me if it would have caught fire prior to my knowledge of this information.
Careful not to torque the line! That is just one of the significant problems I have experienced with owning this vehicle. I said it a hundred times in the video so I might as well type it out as well lol. It also seems like there is no signal going to the injectors either. In may,2001 problem was intermittent and dealer said they could not fix it if it was not broke, and to bring it back when it failed. I also marked the 20 amp fuse for the fuel pump for you. The fuel pump, as well as the fuel pump connector, can not be accessed easily, so I better have a good reason to go in there.
