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.

I have a 2004 envoy which wont move when put into gear. Is this a lockdown mode and how to fix it?

if their is a check engine light have the code read ------no such thing as lock down mode you have limp mode which will let you limp vehicle home or to a shop or off road safely sounds like a transmission problem check fluid --look and smell if it looks burnt brownish and or smells burnt try a flush with a fluid and filter change may gey lucky ---look under vehicle and check the selector cable and connections sometimes disconnect or rot away lastely possible internal problem which would need a transmission specialist to look at

Not shifting on accelleration

Start by ensuring fluid level for transmission is correct. Is the check engine light on? If so, the transmission control module may have code stored in it to point you in the right direction. You can also try disconnectint/reconnecting battery which will reset transmission module.If problem corrects itself,keep driving to see if it reoccurs. If problem occurs immediately, recommend transmission diagnostics b efore costly repairs develop

I have a 2018 GMC acradia denali. The problem is the window shield wipers only work when spraying window.

Likely the multifunction switch but can be a BCM and/or an interconnecting wiring issue. Troubleshooting with a capable OBD scanner and verification of wiring integrity would be necessary to eliminate guessing.Looks like a new switch is less than $50US and if you can DIY, simply forgo a diagnostic charge and try a new switch. Else pay the man.
