I've got an 1989 Chev Celebrity with a V6 that keeps dying. I've had the battery checked, replaced the fuel filter, fuel pump, replaced the spark plugs and plug wires, replaced the main computer and had the fuel pressure checked and the problem still persists. Any suggestions?

When it dies and wont restart, you need to find out what's missing, spark at the plugs? Injector pulse(fuel supply), or compression(not likley the problem) if it starts later.
If all that is ok, check for a stuck EGR, then test fuel pump pressure, If it won't restart, determine what's missing, the engine needs three things to run, Spark at all plugs, gas to all cylinders, and compression in all cylinders, tho an engine may run lacking one in one cylinder, it won't run very well!
