1998 Toyota Corolla CE won't crank or start indicates engine light only instead of all lights on gauges before putting car ignition on ACc

My engine won't even crank or start I tested the
starter the alternator and the battery they where all
fine when I turn my car into start instead of
marking all lights on like it usually does before
starting on Acc it only marks the oil light or
indicates the oil light ONLY I can it be the Switch
ignition?? I thought it could be the oil pressure so I
changed my oil pan gasket since it was really
damaged I searched my car symptoms and it can
be the solenoid so I tried cleaning it I tried the
everything but none of the corollas I searched do
what my car does a guy @autozone told me that it
could be my ignition switch maybe one of the wires
isn't sending current to turn on my starter Wich
prevent s my car from even cranking let me know
what you guys think thank you
