Answer
Your voltage is way too low, and you're at risk of damaging the electronics.  You've got alternator problems or wiring problems.  I'd start by measuring alternator output, and if good, following back to the fuse box and power panel.

The fuel pump wiring itself may be damaged - I've seen the connectors melt
