The crankshaft sensor is by the crankshaft pullie (the balancer)
I have been having problems with finding the crankshaft sensor, what should i do or what can i do?
There is no distributor. The PCM uses a crankshaft sensor and a camshaft sensor to determine when to fire the coils.

A common sensor that could prevent a 1999 GMC Suburban from starting is the crankshaft position sensor. This sensor monitors the position and rotational speed of the crankshaft, and if it fails, the engine control module may not receive the necessary information to start the engine. Other potential culprits include the camshaft position sensor and the fuel pump relay, but the crankshaft position sensor is a frequent issue for starting problems in this model.
To replace the crankshaft position sensor on a 2000 GMC Sonoma, first disconnect the negative battery cable for safety. Locate the sensor, typically found near the crankshaft pulley at the bottom of the engine. Remove the electrical connector and the mounting bolt using a socket wrench, then pull out the old sensor. Install the new sensor by reversing the removal process, ensuring it is securely fastened and the connector is properly reattached, then reconnect the battery.
On a 1999 GMC Suburban with a 5.7L engine, the crankshaft position sensor is typically located on the engine's lower front, near the crankshaft pulley. It is mounted near the oil pan on the driver's side and is accessible from underneath the vehicle. The sensor is usually held in place by a bolt and connected to the engine's wiring harness. Always refer to a repair manual for specific details and diagrams for your model.
The sensor is down on the front of the oil pan just behind the crankshaft pully, which is located at the front of the engine.
The crankshaft position sensor on a 2002 GMC Envoy is typically located near the bottom of the engine, often on the engine block or near the crankshaft pulley. To access it, you may need to remove the engine cover and, in some cases, other components that obstruct your view. It's advisable to consult the vehicle's service manual for specific details and diagrams for your model.
Pretty sure it's at the front end of the crank.
