1999 Ford F150 cranks & no start, theft code 16.

I have a F-150 99 with a code of P1131... Is it
The P1131 means that your upstream oxygen sensor (the one closest to the engine) is not switching rich to lean and back as frequently as it should. This could be due to a vacuum leak, a failing oxygen sensor, or a rich fuel mixture.

Lean mixture - Too much air not enough fuel.
