P0261 - front injector open/low EFI

P1353 - front cylinder no combustion EFI

the data does not support a conclusion.

it seems your front cylinder is not firing. each cylinder requires only 3 things to start and run:

- spark

- fuel

- compression.

check for spark. if you have good spark, ass indicated with a ignition spark tester, perform a compression check. if the compression is good (let's say 120-150 psi) and the reading from each cylinder is within 10% of the other, then I would move to fuel.

it's most likely you either have a bad injector or a wiring problem with the front injector.
