I had this exact same model. If you're not positive all 4 wheels are under power when going forward slowly, check the 4x4 electronic switch. The fuse might be blown.

check the box oil drain plug for metal bits indicates bearing failure or chipped teeth

I would check fuses first, no lights is usually a clue a fuse blew, but since it is connected to blower, you may have blower resistor which blew fuse, so start there is where I would start. All fuse panels have a chart of which fuses control which circuits in vehicle. Good luck FREE-BUSINESSES.com

I wonder if the manual shows some sort of a RESET.

If You Did A Load Test On The Battery to Make Sure Its Not (WEAK) or bad Period!!! then the next step when it doesnt start did you check for fuel and spark? maybe the cps (cranKshaft positioning sensor?? did you check the voltage and ohms of devices? did you use a scanner? did you get any codes ?

unfortunately no ! Your best bet take it to the dealer . The P0420 always ends up being the catalytic converter ! P2104 isn't throttle air control . P2112 - Throttle Actuator Control (TAC) System - Stuck Closed. Description: This powertrain control module (PCM) fault status indicates the throttle plate is at a lower angle than commanded. Possible Causes:

• Binding throttle body, stuck closed.
• Damaged PCM.

Diagnostic Aids: Application Key On Engine Off Key On Engine Running Continuous Memory All GO to DV1 P2104 - Throttle Actuator Control (TAC) System - Forced Idle Description: The TAC system is in the failure mode effects management (FMEM) mode of forced idle. Possible Causes:

• Open or short in multiple accelerator pedal position (APP) sensor circuits.
• Damaged APP sensor.
• Damaged powertrain control module (PCM).

Diagnostic Aids: This DTC is an informational DTC and can be set in combination with a number of other DTCs which are causing the FMEM. Diagnose other DTCs first. Application Key On Engine Off Key On Engine Running Continuous Memory All GO to QE1 P0506 - Idle Air Control (IAC) System RPM Lower Than Expected For Vehicles With Electronic Throttle Control (ETC) Description: This DTC is set when the powertrain control module (PCM) detects an engine idle speed that is less than the desired RPM. Possible Causes:

• Air intake restriction.
• Exhaust restriction.
• Engine mechanical fault.
• Damaged electronic throttle body (ETB).
• Damaged PCM.

Diagnostic Aids: This DTC is informational only and it may be accompanied by other DTCs. Diagnose other DTCs first. If other DTCs are not present inspect the intake air system for air restrictions and damage. If no concerns are present, clear the DTC and retest. For All Others Description: This DTC is set when the powertrain control module (PCM) detects an engine idle speed that is less than the desired RPM. Possible Causes:

• IAC circuit open.
• Air inlet is plugged.
• B+ or VPWR to IAC solenoid open.
• Damaged or incorrect IAC valve.
• IAC valve stuck closed.
• VPWR to IAC solenoid open.
• IAC circuit shorted to PWR.

Diagnostic Aids: Disconnect the IAC valve and look for little or no change in engine RPM as an indication of a stuck or damaged valve. Application Key On Engine Off Key On Engine Running Continuous Memory Vehicles With Electronic Throttle Control (ETC) Refer to the Description, Possible Causes and Diagnostic Aids for the DTC. All others GO to KE1

Sounds like the solenoid for the starter has a burnt spot on it. I don't think leaving the key on is heating up the starter so I do not know what is happening there. Are you getting a lot of water up in the starter so it is freezing over night. I would test the solenoid or replace it.

Make sure your getting 12V at the starter (fm batt) & have a good, clean ground from the batt. Good luck

When this happens check the fuel pressure, I will bet you have none or it is very low.

Check crank shaft sensor and cam sensor.

Is the check engine light on ? What fuel pressure does it have ? Could be the FPDM -fuel pump driver module !
