The Communications error is usually no power to the DTC connector, which is the same fuse as the cigar lighter.

Do you have another key to test with ? IF so, turn the key from off to run ( do not start ) and let the self test finish. If the light goes out, the crank no start could be a fuel pump, fuel pump fuse, fuel inertia switch or fuel pump relay issue.

I had similar symptoms with my 2001 F-150, and it was the fuel pump relay. I swapped it with the trailer tow ( reverse or battery charge, which ever is the same size relay as the fuel pump ) and it was fine again.

I lost the keys to my 97 sunfire so I busted out the ignition now when I crank it it runs for a few seconds and shuts back off and the anti theft light flashes how can I fix this problemail myself?

My info shows you have passlock security system. The key is just a mechanical key, the key doesn't have a pellet or transponder. A locksmith should have been able to make you a new key and it should have worked fine. It's the tumbler that communicates with passlock, not the key.
Since you busted it, I doubt I can help. You need a new lock cylinder, probably a new passlock sensor, then you need to program it.

engine symbol ? That's check engine light , OBD 2 - on board diagnostic's 2nd edition ! Has to do with EPA emission standards ! Engine symbol will be on till vehicle starts and run . Now then when you try starting the vehicle is there a little red light in the center top of the insturment panel flashing really fast ? If so that is for the anti-theft system , when there is a problem with the theft system the computers on the vehicle will not let the engine crank .

Anti theft device

Try the other (spare) key. it could be just the transponder has failed in that key. if not it will be a tow to the dealer problem.

I have a 1999 Oldsmobile allero and I am having trouble with the theft lock, randomly my car will not start and then my security light will start flashing and I have to wait for about 15 min for the light...

You are experiencing GM passlock security system. Yours is starting to fail. When the system gets old it fails to communicate with all the parts of the system that need it. When the communication is broken, the car goes into anti theft mode and and turns off the starter and/or the injectors. After ten minutes it trys to connect the communication again, this is why it will work after a while. Go to this link, it has a ton of info and some ways to bypass this system so it will never happen again.

I have a '99 Ford Ranger 3.0L that won't start reliably(3 times in 2 weeks).When I turn the ignition to "on",the theft light flashes rapidly,and will eventually give me a 1:6 code(faulty link between PATS...

When the anti-theft light is flashing rapidly then either it is not seeing the key,or the transciever module is not communicating with the PCM. It could be the transciever or it could be the PCM is not powering up for some reason. I would first try replacing the PCM relay in the underhood fuse panel.
