I've got an 84 244 DL, it starts up fine, then stalls out after a minute or two. Right before it stalls I believe it is the fuel pump relay that buzzes. The relay that buzzes is in the passanger floorboard. From what I've read on brickboard previously the fuel pump relay should have six blades, the relay that's buzzing only has 5 blades. There are two of these 5 blade relays side by side. I tested the fuel pumps by by-passing the fuel pump relay with a jumper wire from #7 fuse to #5 fuse, and the pumps ran. I checked the 25 amp fuse under the hood on the diverside and cleaned the connections. It appeared to be fine. I replace the 5 bladed relays. The car still stalls after a minute or two, but instead of buzzing it clicks right before it stalls. Any advice or suggestions will be very appreciated.
