CHECK MUFFLER

you may have a vacuum leak or a spark misfire.Take it to a reputable shop to do a diagnostic on it, could be as easy as a bad wire or a vacuum line disconnected...If all that fails the throw a blanket at it, it may be could....Good luck!

Is the check engine light on, if so I would have the codes pulled to find out whats wrong.

Have you checked base fuel pressure before and after cranking the engine ?

We're assuming the transmission fluid is at the correct level and not dark and bad smelling?

The security, antitheft, or passlock light is a visual indication that something in the car's antitheft system is failing. In most GM cars and trucks there is a hidden system that most people are unaware even exists. From the moment you put your key in the ignition, there begins a constant line of communication between your key's security chip or transponder, to the ignition's lock cylinder, and then to the car's TDM (Theft Deterrent Module). These 3 parts are in CONSTANT communication. If the key is in the ignition, then these parts are sending signals to each other. The security light illuminates when that signal gets broken, even just for a second. When the signal breaks, the car misinterperates this as an attempt at theft and goes into antitheft mode. The car thinks its being stolen or hotwired because it is not getting that signal from YOUR specific key. This is why the security light turns on and shuts down your vehicle.

you should drive in 2 auto, unless you are in conditions where you may need 4 wd then you can put the tranny in 4 auto. You don\'t want to drive all the time in 4 auto because you keep power to a solinoid all the time and will cause it to go out sooner.

secrity light on?securt system wont let it start.

TO get that screw out you need to use a tool that looks like a nail puller and you put it under the screw head to lift while you unscrew it. Once you get to the mechanism for the seatbelt, you should be able to free it because it will he able to have slack and the dogs will loosen up. Be mindful of airbags and seatbelt tensioners that are in that area though

getting coolant there,means gasket,I put head gasket fix ,works good.

if your engine falters only when under acceleration it is one of two things either bad fuel pressure or bad spark plugs wires and ignitiion components know to us mechanics as a load miss

Just for the record, its a throttle body not a carb.Sounds like the injectors are not getting power or a ground signal from the computer.You would check them with a meter or low voltage test light.

there is adjustment down on the ******. I will send you a picture, what you will need to do it put on the e brake,and block the tires. on the drivers side of the ****** the shift cable is located, pop off the cable from the arm and pull the white clip, when push the arm foward that is park,and then easily pull the cable to the arm and put back the white clip

When you say it fires, are you checking for spark at the plugs ?In most cases you have to figure out if it is spark, fuel, or compression to proceed. A mechanic would also check the computer for trouble codes but you would need a scanner or code reader to do that.

there has to be a gasket failure somewhere..doubt if the truck has a mechanical pump on it but if so equipted the pump diaphram has failed and is pumping raw fuel into the engine block.. replace this pump and the issue should go away...most pumps were mounted in the fuel tank and are electrically operated..so it may be a tbi gasket failure or line leak somewhere check all and repost findings..thnx

You must remove the dash to replace the temperature control blend door and its actuator, it is combination repair.
