Where is the Fuel pump fuse located in a 1995 GMC 1500 Sierra?

Possible shorted fuel pump relay. Disconnect relay to see if pump shuts off. If so, suspect relay problem. This vehicle may have 2 relays. Try the one in the underhood relay/fuse center first. Here are some pictures of relay locations. If equipped with a secondary relay, it will be #3 in the lower picture for location

You checked the fuel pump relay in the engine compartment fuse / relay box ? The fuse that powers the fuel pump ? ECM B fuse 20amp - engine compartment fuse panel . Is the PCM turning on the fuel pump relay ? Do you know how to test automotive electrical circuits using a DVOM - digital volt ohm meter an a wiring diagram ?

GM Fuel Pump Relay Testing

Do you hear the fuel pump running on the prime cycle (when you turn on the key) (runs for 3 seconds) or when you have oil pressure?Have someone listen back by the tank for the wrrrrr.If you do have to change the fuel pump,make your life easy and just tilt up (lift) the pickup box from the drivers side to access the fuel pump.Takes 20 minutes to change it that way.

run the fault codes
could be a problem crank/cam position sensor or bag ground wire connections

I think it is located on the firewall on the passenger side of the vehicle. It is directly below thae passengerside windshield wiper. Look for a plasctic cover with writing on the top such as "Power block" or "Fuel pump relay" or "Fuel pump Fuse

the fuel pump runs off the engines oil pressure switch upon starting. when the oil pressure is up to normal psi the fuel pump relay takes over until you shut the engine off.

The fuse is actually a Relay Switch and its located in the Fuse Relay Center on the driverside of the engine compartment. The Black Box is labled Fuse Relay Center, the diagram on the cap displays which Relay is the Fuel Pump relay...the Relay switch is usually $8-$15 depending on where you shop

iam from sunny spain please be more specific??do you mean you have no fuel pressure into common rail injector feed,if so check for feed to pump in the fuel tank..if you have a feed then renew the pump.the pump wires to sender unit will be bigger and thicker than the gauge sensor wires

Have you check the injector relay or maybe a fuse for injectors.
