Wants to start spits and sputters but wont start! the car was running when it died and wont start back up! is getting gas has spark it turns over! any suggestions on what to check or what it could be?

If it is backfiring and dying I would be willing to bet you have a crank angle sensor going out when it get warmed up. Also check to see if your fuel pump is running by listening in the gas door with the cap off. I have had them do this when the fuel pump gets hot it quits pumping fuel.

Go back to basics, spark and gas getting to the cylinders? Does the engine crank at normal speed for cranking? If so, check spark and gas. If it's in time, it must have lost one or the other.
One easy way to check, spray some stating fluid into the air intake (take off the large boot) and try to start. If it runs or almost starts on the fluid, you know it's a gas problem. If it doesn't fire at all with the fluid, it must not be getting spark. Then you check out or test the ignition system.

you need to read the manual for the machine you are hooking to the vehicle .
These are errors not codes you need to understand how it works better.

Please check the following.

Check Spark at the plugs. (all of them)
Fuel filter not clogged.
Choke working properly.
Rev the engine while shooting carb cleaner through all the ports.
pull and clean and check your mixture screws. (Remember to EXACTLY count the turns out and go back in the same). See if this helps. Mike

remove coil wire at distributor and plug a HEI GM tester spark plug to see if spark at ignition coil if not test ignition coil for current and signal not short to ground

If you have not replaced plugs start there A bad map sensor will also cause black smoke and poor running

This could be a blockage in the carburator,try to clean it, especially the valves. There is a specific spray for the job on the market. You might need to dismantle it.

Broken wires to fuel pump and little rodent of some kind chewed thru it. the power steering pump shaft was broken so it got fixed cost about $450 parts and labor!

have the fuel preasure checked may not have enough preasure, the car will start but will shut down when trying to accel, good luck.

no spark but 12v at coils
