Hit bump, fuel pump fuse blew..
First of all, thanks to knowing what i know from here, it was no big deal.
But..hit a bump on highway, car dies.
Pull off ramp.
Crank no start
Ok..fuel issue.
Swapped relays, no joy.
Check fuse, blown.
New fuse, fixed.
What would pop a fuse on a normal stiff highway bump?

There's a few things that can happen. Start with the most likely, first.
The fuel pump is supported by "rubber feet". These can deform/break over the years and the pump might be oriented in such a way that the "positive" wire can hit the fuel pump cover, when you hit a bump. Remove the cover and see how the pump is oriented, in relationship to the wires. Sometimes simply rotating the pump will move the wire far enough from the cover to cure this problem.
Look at those rubber feet. If they are deformed/broken, you might want to get a new set.

thats my answer....the pump rotated enough to hit-short under the force of the impact which blew the fuse....

Had a short in my O2 wires that would cause my fuse to blow as well. Had it replaced with the fuse and was back in business. Guessing there's a short in your O2 wiring.
