I have a 2001 saturn that ran out of gas put gas in it wont fire up checked the fuel line presure release no gas in the line checked fuse all good..... do you think its the fuel pump?


THE ELECTRIC FUEL PUMP IN THIS CAR IS IN THE GAS TANK AND IT IS COOLED BY THE FUEL IT RUNS IN, WHEN U RUN OUT OF GAS YOU SEVERLY OVERHEAT THE PUMP AND THEY SEIZE UP, WHICH IS WHAT HAS HAPPENED TO YOUR PUMP, U WILL NEED TO REMOVE THE GAS TANK AND REPLACE THE ELECTRIC FUEL PUMP.

Where is the fuel pump fuse located on a 2001 gmc sierra 1500 ? i replaced my fuel pump and now i do not know where the fuse for the fuel pump is .


The underhood fuse panel is marked and the fuel pump relay is there as well and they fail as the pumps fail tooand they need to be replaced if the pump does any way. The ground wire for the pump is sometomes overlooked when putting the tank back in as its on the top of the frame rail on the drivers side nearthe tank. It can be dirty too. Lesten for the pump running by having someone cycle the key with your ear against the tank it should come on and shut off a few seconds later. if its working. some can be put in wight the wires backwards and they run backwards but make no presure. Chaek for fuel pressure at the fuel rail. and many pump failures are because the filer is stopped up or theres somthing other than gas in the tank water) ( sugar ) some new pumps don't make enought pressure. Below 50 Lbs. it won't start. Adding gas or even carb spray to the air inlet may get it stasrted. The air in the system may get out then and it'll be OK. Sometimes the battery will be too low to turn the pump on but the engine will still crank

Check fuel presure.I believe its 61 to 65 psi, with little or no drop off in ten minutes.V-6 access port for fuel presure is at left rear of engine,(remove dog house to access). Fuel pump is in fuel tank.Use AC Delco only, there is a updated wire harness conector for these.

Fuel presure dodge diesel ?


all i can tell you is that as long as you dont go below 4 psi you should not starve injection pump, this is a minimum psi though., 10-13 psi is average on my 2002 at service port.
