Car won’t start but all the lights come on. Can’t put in gear in ignition start mode pedal is stiff.

Sounds like the battery may be too weak to crank the engine, or there could be another starting system problem. Hands on testing is needed. No suggestions to be made here other than to obtain the assistance of a battery test, jump start attempt, or hands on evaluation.
