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.
