Hello, What we are going to need to do is determine what is missing. Spark, fuel or both. The easiest way to see if engine is getting adequate spark to run car is to spray some carb cleaner in the throttle body. You wil need to remove the big black hose at t body and gently spray a little cleaner in it. Try to start car. If it starts then stalls, then we know the ignition is not the problem and by your desdription, would be a fuel pump. It is located under the back seat set into gas tank. You could do this yourself.
If the car does NOT try and start with cleaner, suspect an ignition problem. You would need to remove the end of coil wire from distributor cap and with insulated pliers or other, hold the end of coil wire very close to ground ( metal) Crank aand watch for spark. If none. suspect ignition module located on distributor. It may be getting hot and cutting out then cooling for restart. If you HAVE spark at coil wire, then you need to pull one plug wire from spark plug and do same thing to check for spark. If you do NOT have spark at plugs, BUT have spark at coil wire, you have a problem with distributor cap and rotor. You will need to do the tests. I hope I have helped in narrowing down your problem. LMk and Thanks
