Your 92 Lumina will not fire it was in a minor accident and has not fired since you have replaced the crank sensor and it still will not fire what could it be?

Not sure if the '92 Lumina has an inertia switch or not. The inertia switch (also called fuel shut-off switch) will trip in an accident and shut off the electrical power to the fuel pump. You might want to check your owner's manual to see if there is one and where it is located. Also to learn how to reset it.
