It backfired and low engine power is a sign that the fuel pump is going out but to be sure we need to check the fuel pressure. here is a guide to help and I have included how to change the pump out in case you need it:

Fuel Pressure 400 kPa ±34 kPa 58 PSI ± 5 PSI

You can rent a fuel pressure gauge at the auto parts store. Check out the images (below). Please let us know what you find. We are interested to see what it is.
