It's possible that the BCM is causing these issues, you may want to check the fuses first though. Have you checked the charging system (battery, alternator etc.)?

The fuses are okay and the battery was checked. The alternator was not. Neighbor who has a repair shop tried to pull codes on the vehicle but the computer could not communicate with the BCM. Thanks for the quick reply.

Does the engine light come on at all?

The check engine light is on, but it was on before for the fuel sensor. The traction lights flashes several times and then remains on and the security light just stays on. (Does not flash at all)

Hate to say it but it does seem like the BCM is not communcating with the vehicle for some reason

Would it be the front or the rear bcm? And where are they located? Thanks

Theres only 1 BCM on your vehicle and its located under the left rear seat

Is there a way to test the bcm?

Theres really no way to actually test the BCM, here are some giveaways of a failing BCM though.
Pay attention to your vehicle. When a BCM is malfunctioning, the electronic components of the vehicle will begin acting in strange ways and not working properly. Some of the possible causes of a malfunctioning BCM include the clock on the radio not keeping its time and reverting to 12: 00 when the vehicle is turned off, then turned on again.
Check to make sure all the electronic devices are working properly. If you use a key fob to lock and unlock the doors, the function may not work. Or if the doors do lock and unlock properly, other things can happen in conjunction with the lock/unlock action, such as the horn honking or the lights blinking each time you use the fob.
Turn the radio and CD player on. Sometimes a CD player will stop playing a CD and will begin broadcasting a radio station. The frequency of these actions depends on the severity of the malfunctioning BCM.
Check the fuse box if you suspect that your vehicle's BCM is on the blink. Make sure all the fuses are in good shape. If any are burnt out, replace them immediately. If you have replaced blown fuses and you are still experiencing problems with your vehicle, take it to the dealer so the mechanics there can run a diagnostics test on the vehicle.
Take your vehicle to Auto Zone or Checker or another similar auto parts store. They also have the capabilities to run a diagnostic test on your vehicle if you are short on time or can't take it in to the dealer. The only drawback to taking it to an auto parts store is that, most of the time, the person performing the diagnostic test can't read the code and will refer you to a dealer, anyway.

At this time the car won" t crank. The radio, power locks, windows and interior lights are not working at all. The instrument panel lights and blower fan are the only things that work inside the car. So I guess we are looking at the bcm as being the culprit.
