Asked by for the 1999 Chevrolet Tahoe
1351 is an electrical issue with the injectors . check for any rodents living under the plastic covers causing wiring issues. common failures.

1461 does not come up in my system but 461 is fuel level sensor fault with either the guage or tank sensor failure.
either way, you need a shop to track these down and do the necessary tests.
