My 1984 245 wagon stopped abruptly on Memorial Day, and I haven't been able to get the engine running. Was driving along and the engine just quit. Fortunately only 1/2 mile from home, so got the car to the house.

Tested for spark, and I've got spark.

The 25amp fuse is fine - I replaced it a couple of years ago, and it still has power on both sides.

In the fuse box, I have power at Fuse #6, which is for the main fuel pump. However, there is no power at all for Fuse #5, the in-tank pump.

If I read the wiring diagram correctly, Fuse 5 gets power from the fuel pump relay. Unsure which of the two relays under the dash on the passenger side is the FP relay, so I replaced both of them, but that did nothing.

Any thoughts as to how to proceed? My fuel filter is also quite old, and it's been on my list of things to replace (I have the new filter), but I doubt the filter could've caused the car to stop so suddenly.

FYI, car has about 270K miles on it. I bought it 110k miles ago, and to my knowledge both fuel pumps are original.
