99 ranger won't crank, periodically, has anti theft.

I looked at your security system, it is starter motor disable and fuel injectors. You can usually get the starter crank, but, if it is the security system, it still won't start because of fuel injectors. I don't know any way to bypass security system. You can check for applicable trouble codes, if there are any?

Car will not start

You probably can't.
If the anti-theft module is in the cluster, you would need the correct key chip for the car the cluster came out of.
You might be able to bypass the passkey system by running a wire to the fuel pump relay and other components.
You may need a shop manual to find the circuits.

Replaced the fuel pump. the car starts, but won't stay running

The anti-theft system will keep the car from being driven, so I would start there. You may need to reset the anti-theft or check the ignition key for problems.

I changed engines from a 1996 chevy cavalier to a 1997 cavalier,i don't get any gas or fire won't start

These cars were made with an anti theft security system. If you swapped motors, you may have interupted that system causing the the security to turn off the ijector fuel. Just a thought.

My car will crank but won't stay running, i replaced my alternator and my fuel pump relay but it still won't steay running

Could possibly be the anti theft system. This system can actually turn off your fuel injectors 1-5 seconds after starting. http://vatspasslockpasskeysecurityhelp.yolasite.com/

Is there a light on the dash that says SECURITY? These anti theft systems have been known to disable fuel.

1997 Chevy Cavalier Starts and then dies after a few seconds.

Find a good auto wrecker, and try replacing the mass air flow sensor.

Http://vatspasslockpasskeysecurityhelp.yolasite.com/ Go to that link. You are exactly right. The engine swap has confused the anti theft security system. It can disable the starter and/or the injectors/fuel. There are ways to bypass these systems. You can do it yourself too. Ive personally done dozens of these bypasses, and they work great. Good luck
