I'm suspecting a shot fuel pump - no noise when turning the key. Fuse #11 is OK. I checked the relay and the pencil marks on the cover and base tell me it's one that I must have resoldered some time back. Before I pull the pump, I want to check for elec power where the wires enter the tank. Can someone with a good wiring diagram tell me what color is the wire that powers the pump?

Note: About a week ago we ran the gas tank REAL LOW before we pulled in and filled up. I'm wondering if I killed the pump by sucking air or picking up setiment.

As always, thank you.

Which pump is it that you want to check? The pump in the tank is the pre-pump but the pump that you hear when you cycle the key is the main pump under the car. Either way they both power up off of the pink wire that gets it supply from fuse 11. If it is the pre-pump then check for current at the pink wire in the 4 pole connector in the trunk, kind of by the power antenna goes. If it is the main pump it is just as easy to check right at the pump. It will be the pink wire that goes into the yellow housing on the pump, usually the upper housing. The lower housing is black and it is your ground.

Oh yeah - I forgot to mention.... It's a Regina system (a single high-pressure pump in the tank). Regardless, I'll look for pink.

Thank you.

You know I thought it might be a Regina system and being a California Volvo tech they did not place much emphasis on that system in Volvo school but I did seem to recall that it was a single in tank pump system. Here's the kicker though Volvo green book TP 31571/1 shows that system with both pumps!! I thought that was screwy but since everything supports a pink wire regardless of which pump or system I decided not to pursue it any further.
