Continues cranking. Wont turn over. what s my next step?

I have a 1990 Oldsmobile Siloquette van. It continues cranking , but won't turn over. What should I do to find out the exact problem.
I was thinking that it might have something to do with the fuel pump, fuel infector, fuel filter, or fuel pump relay?

A vehicle needs fuel and spark to run. If the vehicle isn't running, then it is not getting either fuel or spark. You can use a test light or spark tester to check for spark. The spark plugs attach to plug wires. The wires attach to coil packs which is mounted on ignition module. The module has wires that go to crank shaft position sensor which provides power for the spark. You can test sensor with an ohmmeter to see if there is resistance. If not, it needs to be replaced.

Fuel is from fuel pump, through fuel filter and through fuel pressure regulator to fuel rail, then to the injectors.
On the fuel rail, there is a test port, You can place a rag over the test port and press the valve in. There should be lots of fuel pressure. Or you can use fuel pressure tester.
Also, when you turn key to ON position, you should hear the pump turn on for a few seconds. If you cannot hear it, then check the relay with an ohmmeter to see if it is good. You can use a voltmeter and check power to the relay and to the pump as well. Check fuses if needed.

You mean it cranks but wont start (cranking and turning over are the same thing) When cranking, rap on the fuel tank, if it then runs, the pump is bad and will need to be replaced.

Cutlass ciera wont start


Does the starter spin the motor at normal cranking speed? If there seems too much friction, try turning the engine over by hand to check if the engine turns freely. Put a socket and wrench on the center crankshaft pulley bolt and turn clockwise. If you cannot turn the crankshaft with a wrench easily, then the starter can't either. Turn the crank all the way around to check for something preventing cranking.
Is the battery still enough power to crank at normal speed? If it's already too low, recharge it, and try again.

Hi, if your motor turns over ok & appears to be getting fuel, I'd probably check for spark by putting a spare plug in one of the leads & turning the engine over to see if it sparks, if it doesn't spark maybe it's your crank angle sensor/coil etc.
