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.

What will cause a 2009 Pontiac g8 gt 6.0 motor to not fire one side of motor

I am reading something all about Limp Mode

Which seems to be all about
Thread G8 GT Limp Mode P1516 P2101 P2176

the car being driven at extremes... in other than
prescribed parameters ... causing OBD codes to be posted

My guess you are experiencing Limp Mode

I tried to pull up schematics from Autozone... but your car is not supported Looking for common coil (or coils) fuse(s).

G8 GT Limp Mode - P1516, P2101, P2176
Particularly this last thread [4 cylinder failure]
... but read on

and disconnecting the battery [ ill advised ] to reset the "condition"

Lifter failure or stuck in limp mode or WHAT is going on PLZ HELP LS1TECH

Not Limp Mode

How do I fix diagnostic codes of p2101 p2119 p0172and p0368 on a saturn ls300 2004 how can I fix this please

I guess not! Rarely does a vehicle set four codes at once. Was this something that happened at the same time, or have you had a check engine light for a while and just now got driveability issues bad enough to warrant repairs? Regardless, here's what I was able to find for you.
1. The P2101 and P2119 codes may be related. They both refer to the TAC (Throttle Actuator Control) Module. The code is set if the module reports values the ECM is not expecting to see. The 2101 code basically says to replace the TAC. The 2119 codes says you could inspect the throttle plate to see if carbon buildup is preventing it from closing properly. I would do the inspection and cleaning if warranted and then see if the codes clear and stay away. Otherwise replace the TAC.
2. The P0172 is a veritable Pandora box of yuck. The code is called "Fuel Trim Rich Bank 1", which is a polite way of saying "I hope you have a fat wallet". The list of possible causes here is as long as you arm. They include:

  • Faulty front heated oxygen sensor
  • Ignition misfiring
  • Faulty fuel injectors
  • Exhaust gas leaks
  • Incorrect fuel pressure
  • Faulty Mass Air Flow (MAF) sensor
I am linking you to the page I researched for this code as there is a Saturn Factory Service Bulletin regarding this code.
P0172 Saturn Fuel Trim System Rich Bank 1
This may be a good starting point to try to remove this code.
3. The P0368 code suggests a bad camshaft position sensor. You should be experiencing driveability issues (stutter/stall) with this code.

Hope this helps!
