Died while driving......meaning running down the road and it just quit, right?

If so, first step is check for spark. Don't bother with plugs yet since we know four plugs don't all fail at the same time.
If you have spark, it verifies that the cam and crank position sensors are functioning.
It also proves the camshaft(s) are turning, meaning there is no belt or chain concern.

I don't know what engine we are discussing, so I don't know if it has belt driven cams.........but most Mopars had belt drive back then.

If there is no spark, you should be able to see the camshaft with the oil fill cap removed......have someone crank the engine while you observe for rotation of the cam.
If the camshaft is turning, you can home in on one of the two position order of failure, for no known reason, exchange the cam position first, crank position second, ignition module last.
One of those steps should get spark and a running engine.

If there is spark, the fuel pump becomes, to help make that determination, pull the air inlet hose off the throttle body, fire a healthy shot of carb cleaner into the throttle body while holding the throttle open, reinstall the hose, and crank the engine.
If it starts and dies, you have proven, by substituting something to burn, a no fuel condition.

The owners manual may indicate the car has a fuel pump reset switch, known as a rollover switch. These are common on Fords, Sometimes on Chrysler, never on GM.
If one is listed, reset it.

You should be able to hear the fuel pump run for one to three seconds every time the key is switched to the 'on' (not crank) position.

If there is no may be time to enlist a professional that has a means to measure pump pressure, and pump circuitry.

Going further makes me sound like a shop manual so I'll leave it at that.
