You'll have to do some investigating to find out.
First, is it a lack of spark to the plugs, or fuel to the injectors ?
Then, is it something getting hot like a relay or the coil, or something like a build up of pressure in the gas tank.

SOURCE: starts and runs 3-5 seconds and shuts down

Sounds like your security system is shutting the car down. You should be able to leave the key on for 15 minutes and it will reset itself. Make sure you are using factory keys, and they are in good condition.

On some models, the Engine Control unit has a power supply relay. These relays some times get internal dry solder points. After driving for some time the the solder will get hot and separate. When it cools down it makes contact again. You will have to replace this relay or open it up and re- solder the solder joints. The relay is usually located on the main relay station in position 3. the relay station is located behind the right dash panel.[right hand drive vehicles]. You may need to refer to a manual for your specific model to find the exact location of the relay.

trapped air. When temp needle climbs to 1/4 way, loosen coolant temp sensor to bleed off trapped air in cylinder heads. Air is gone once coolant starts to stream out, but only open slightly at a time. May have to do in increments as trapped air will cause rapid overheat

I have a 1993 Pontiac transport van and it will start up and run for 5 or 10 seconds and die


You may want to do a fuel pressure test to start. The pump could be defective. The fuel pressure should hold steadily and not decline with the pump off. If the fuel pressure falls, you either have a fuel leak, stuck injector, faulty fuel pressure regulator, or a bad fuel pump check valve. If the pressure holds at the correct spec, note the pressure as the engine runs and then dies. If the guage shows correct pressure, you can then move on ruling out the fuel system.

engine wiring harness upper and lower could be degraded, coil could be bad, throttle positioner, fuel distributor could be bad and depending if its a half year car and you have an OVP that could be bad. Also after a full tune up have someone adjust the duty cycle.

In 1996 the Trans Am came with an LT1 unless an LS1 was swapped in. Timing is not adjustable in either engine though. Why do you feel you need to adjust the timing?

you should probably just replace the iginition module if someone didnt test it with a graphing meter or lab scope. also check the fuel pressure. those are signs of the ignition module though

provided you don't have a vacuum leak, (check all hoses for tightness and cracks with engine running) it's probably your idle air control valve or sensor.
