WONT CRANK OVER

1987 Buick Electra • 6 cylinder FWD Automatic • 110,000 miles

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.
