1990 GMC Truck V8 Four Wheel Drive Manual 120000 miles

It has only slight hesitation starting first thing in the morning but after warming up it won't restart until engine cools. The engine will crank just fine but won't turn over. If I leave it still at work all day then it restarts just fine. I just can't move it within a couple hours. I've put heet, fuel injector cleaners, and new gas in the tank. I've replaced the fuel filter, spark plugs, and spark plug wires. Someone told me try the distributor.

Do you

Could be one of the electronic items in the distributor(pick-up coil or ignition module). Have you checked to see if it has spark when it wont start?

Use a spark tester so you dont get shocked. They are cheap and available at auto parts stores. Test for spark out of coil and out of distributor
