3.0 Milano Fuel Pump relays

Hi,

Does anyone have a pic of the location of the fuel pump relays for a 3.0 Milano (1987). My Dad's car is cutting out intermittently and by researching on the forum much information points to the FP relays. Any help would be appreciated.

Symptom - car is running and cuts out and at this point will immediately restart. We want to fix it before it gets worse.

Thanks,

They are on the firewall in the engine bay on the passenger side. Look straight back from the coolant tank and they are to the right.
The wires from the AFM switch are red/black and pink/black. I have them jumped out on my one of my cars because the AFM switch had an intermittent fault.

this was a call back. from alfa same -time as the timing-belt tensioner. do what last post said and jump the wire from the relay to the pump the problems at the B-piler but you have to take half interior out to get enough slack for the harness. It was only on US harness. Not euro!

I had a problem with my Verde cutting out and then starting up again almost immediately. I first had to figure out if it was ignition or fuel.
Step 1. I confirmed that the tachometer was still working as the car slowed when the engine had cut. This told me that the ignition system up to the coil were fine. I swapped in a new coil, distributor cap and rotor because they were inexpensive and hard to test. I still had the problem.
It could have been the coolant sensor going bad so I faked it out with a fixed resistor. I also jumped from the fuel pump wire to the wire that brings 12 volts to the combination relay. The car did not cut out now but it ran rough due to the fixed resistor in place of the coolant sensor.
I put the coolant sensor back in circuit and the car still did not cut out.
Now I removed the wire that jumped to the fuel pump and added the jumper for the AFM switch. The car still ran fine which proved that the problem was in the coil circuit of the relay.
Finally, I removed the AFM switch jumper and the problem returned. That proved the AFM switch.

If jumping the fuel pump circuit had not fixed the problem then I would have started looking into the fuel injection system.
