How does the crankshaft position sensor operate what is it Job to do? and how do i test the injectors for pulsa with a noid light where are the injectors located on this vehicle?


The crank sensor is needed for the coils to fire. It is on the drivers side, mounted in the engine block back by the transmission. The injectors are under the plenum. The plenum wraps around them. I wouldn't worry about them right now. And your probably right about being flooded. I would throw new plugs in it when you replace the sensor.

Do a 2004 Envoy SLT 4.2L have a Ignition Module?


Crankshaft position sensor,cam sensor . your vehicle should have coil on plug , a coil at each spark plug !
Ignition Coils
Each ignition coil has an ignition 1 feed and a ground. The PCM supplies an ignition control (IC) circuit. Each ignition coil contains a solid state driver module as its primary element. The powertrain control module (PCM) signals the coil driver to initiate a firing event by applying a signal to the IC circuit at the appropriate time. When the signal is removed, the coil fires the spark plug. The spark plugs are tipped with platinum for long wear and higher efficiency.
During normal operation the powertrain control module (PCM) controls all ignition functions. If either the crankshaft position (CKP) or camshaft position (CMP) sensor signal is lost, the engine will continue to run because the PCM will default to a limp home mode using the remaining sensor input. As mentioned above, each coil is internally protected against damage from excessive voltage. If one or more coils were to fail in this manner, a misfiring condition would result. Diagnostic trouble codes are available to accurately diagnose the ignition system with a scan tool.
If a crank sensor is replaced a Crankshaft Position System Variation Learn must be done and a scan tool is need to do this.

2004 GMC Envoy SLT 4.2L the engine will crank but want start why?


P1516 = Throttle Actuator Position Performance
P2101 = Throttle Actuator "A" Control Motor Circuit Range/Performance

Both of these codes indicate a problem with your throttle position actuator system. I'm not sure how GMC/Chevy treat this, it's possible that if the PCM/ECM will not allow the engine to start if the throttle actuator is not working properly (it may cause the engine to accelerate rapidly when running). You could try replacing the throttle actuator, but that may not solve the problem if it's a wiring issue. Best to have it checked out by a qualified mechanic.

The engine will crank but will not start why?


Do you have any codes or an engine light on, in your dash board ? Have you checked for spark at your plugs ? There are many things that could cause a vehicle to not start. Bad camshaft/crankshaft sensors. Poor ground wiring. Defective spark plugs or wires/coils.
