A few days ago my car died in my driveway. I knew it was the fuel pump(Walbro gss317) when i couldn't hear the pump turn on when the key is turned just before ignition. So I replaced the fuel pump and it was fine for a week. Just within this week, the car died again. This time it was on the road. I had it towed to my favorite shop. After taking it to the shop, I learned that the plastic mesh filter screen attached to the fuel pump was coming apart. Parts of the filter were being sucked into the pump and seizing it. I now have the stock filter screen on and that shouldn't come apart. I can't believe it was something that petty to screw up my ride.

 

A while back when I was looking at fuel pumps online, I noticed that some of them had a warranty that was only good if you replaced the mesh filter at the same time as the pump. Are you saying that you did replace the whole pump/mesh filter assembly with an aftermarket and the aftermarket mesh filter caused the problem? Was it your old stock filter screen that you put back on?

Turns out my problem was the main relay, not the filter pump so I re-soldered that and so far, so good. However, it would be good to know whether to avoid afermarket fuel pump fliter assemblies if that is what caused the problem.

 

It was the aftermarket fuel pump filter that came with the pump kit that fell apart. I now have the stock filter in.
