1987 Buick Electra Limited with the 3800. It Has 110,000 Miles. You have to spin it over 3-4 times for 5-6 seconds and it finally cranks. I have done a tune up on it which included plugs, plug wires, oil, oil filter , fuel filter, PCV valve, and air filter still has to spin over 3-4 times before it will crank any ideas or test that might help fix this problem.

Sounds like fuel pump relay , gm uses the relay to turn the fuel pump on for 3 seconds when the key is turned on , after that it uses oil pressure to keep the pump on , have someone at the rear of car turn on key don't start just turn on listen by fuel tank for the pump , if you don't hear it replace relay. If you do check fuel pressure .
