I have also had issues with boost switches and ended up filling the switch with solder.

I noticed the wire that connects to the boost switch (it is a ground) was getting pretty warm / hot. This causes the diaphragm in the switch to melt / fail.

I THINK my problem was caused by either a bad relay or the older fuel pumps that might be near the end of their lives and may be drawing extra amperage. You can run a volt meter from the relays in the trunk to get a gauge on how the 2 pumps compare.

I don't think it is a switch issue.
