Crankshaft Position Sensor

What model and litre size of engine? I looked at a C1500, if you have distributor, no crank sensor. Have a helper crank it, while you visually check for spark at the plugs. If you have spark everywhere, use a gauge and check fuel pressure. Any applicable trouble codes?

There is a pick up coil which does the same job as a crankshaft sensor. Check out the diagrams (Below). Please let us know what happens.

This vehicle is not equipped with selected component . How can I help? does the vehicle has problem starting?

We do not have spark, we should check for fuel.
There is an electric fuel pump underneath. When starting, Can you hear the fuel pump?

Yes either the ignition module or the distributor pickup.
They will need to be checked , because they are most likely to cause that problem.

When you install the new distributor, line up the vacuum advance in the same direction as the old distributor was pointing, rotate the shaft so the rotor will be pointing approximately in the same location as the #1 spark plug terminal, then slide the distributor into the engine. The angle of the drive gears will cause the rotor to rotate slightly and the distributor slides all the way into the engine. Replace the distributor hold down clamp and nut, but do not tighten.

Start the engine and use a timing light to adjust the timing to specifications (typically 6 to 10 degrees of advance with the vacuum advance hose disconnected and plugged at 550 to 650 rpm idle speed).
