Where is the Alfa Romeo Fuel pump relay fuse located?

Does the fuel pump run? The inertia switch, if tripped will prevent the fuel pump from running. If the pump runs but the car doesn't start than it's likely a problem with the fuel pressure regulator or the bypass internal to the pump.

no idea i would expect to find it under the bonnet in a box their ,have you checked for power to the pump ?

Generally a FPR failure won't cause a non-start. Both your Fuel pump fuse and relay are under the package shelf, behind the front seats on the right hand side. The shelf has three screws that are kinda hard to see and some Velcro holding it down. Also thick your inertial switch. The white button should be up.

Could be the main or fuel run relay located in the compartment under the luggage rack, passenger side, main relay also, fuse for the fuel relay 8amp. Electronic Control Unit is also located there.

Could be electrical, Hook up a timing light, three leads: Power, Ground, and one that goes around the wire to #1 cyl. Turn the engine over and see if there's firing. Note: u can check all 4 spark plugs this way.

Fuse lead goes to pin 30 of the fuel relay, u can jump 30 across to 57 and check for the pumps running, if not, change-I suggest both relays, main and fuel run relays. Both pumps get their 12v DC from the fuel run relay, both should be running when you switch ignition switch to on, then a tachymetric signal is fed from the coil to the relay to keep it running.

Hi

Make sure to check the fuses, most of the time when this pump goes bad it blows the fuse, and fuses sometimes get corioded and dont make a connection take a look at the fuse box.
Fuel pump is located In fuel tank .Also fuel pump relay s located in front of batteryi

In fuel tank
Also fuel pump relay located front of battery

fuel pump, fuel pump relay or fuse, or crank sensor.

the crank sensor is located near or behind the main bottom pulley on the front of the engine. it is a very likely problem and is usually an easy replacement, but the fuel pump and its fuse & relay could be the next most likely problem.

I have an 89 one in fuel tank and one under car near differential, drivers side
