no power to fuel pump on 1991 Lincoln Town Car

the car was cranking fine the day before the next day it wouldnt start usually i can hear the fuel pump come on but now i cant the fuel pump relay was burned. i replaced it it still no power to the fuel pump what can i do. its just odd how it will do when i havent been having problems with it

The fuel pump relay is a good first place to look. The PCM relay is the same shape and size and can also be an issue. However, you may have a fuel pump electrical problem causing it to not activate. Have a fuel pressure test performed.

However, before you do that - check the fuel pump emergency shut off (inertia) switch in the trunk - just on the off chance that it is tripped.
where is the pcm relay
Same relay box as the fuel pump relay.
