We can't know this.. Most of us know what the part is when we see it on the vehicle. pa66 is an after market part. Manufacturers number are longer and say GM on them. If it electrical, what happens when you unplug it.. Or what the problem now?

Check again for the codes, more than one fault code perhaps.

Not likely take to your dealer, competent repair shop or auto parts store to have error codes read for Engine systems problems.

The transmission sensors are tied in with the ignition system. If something detrimental to the vehicle is happening in the transmission it will shut you out of starting it. You will have to have this checked out by a pro.

contact your GM dealer as there is a recall out on all GM products that covers the past 12 years for a problem ignition switch it doesn't matter if it is new or second hand All GM vehicle cars now being made have no hole in the key for a key ring as a result of the recall

IT is caused from, Excessively worn friction material or improperly aligned backing plate//or pad shim. You said that the pads have been changed, so maybe the shim for the pad is at fault. Hope this helps! God-Bless! clean the shim mounting and that may work.

First remove bumper cover--pad is underneath.

What button? Don't think you have one. Check owner's manual.

Since you appear to be a DIYer, I highly recommend a repair manual, you will want it again anyway. From your library, from your favorite Auto parts store, or try online filepeep.com, or manualslib.com

Lots of black smoke in the back i had a few problem like that it was the spider in the intake there a central injection system in it its 6 plastic pipe that goes to the cylinder 1 per cylinder 1 or 2 pipe crack and spray gas in the intake your oil must smeel like gas even if its not old let me no after that your car gonna run like new its not a cheap part but you got no choise thats for the question james

My guess is you want to adjust the transmission kick down cable. because why? It doesn't shift to lower gear when you push the throttle pedal down hard? I recommend you review the Repair manual at your library. or http://www.filepeep.com/ if they have it or manualslib.com

Fuel. Check fuel pressure. Replace the fuel filter. When you do this and if you still have problems. Then go after the fuel injection. It is under the plenum on top of the engine. This is a pricey part. I would replace the fuel pressure regulator first(still under the plenum) then replace the spider injection, as they call it. But when you get in there and you see the plastic injector lines broken, replace it all.

under drivers side door by frame

Yes, if you have the proper tools to do so. The problem is finding the right replacement seal or seal kits.

It is on the inside of the truck's frame almost directly under where the driver's seat is located.

No, there isn't a switch. Check the trans fuse.Could be eatx fuse. Could be the transmission is old and tired.

Worn out key cylinder or ignition switch. Cant tell when key is off. There is a wire which as you put in the key it makes contact as the the key pushes this metal contact up. You can unplug it. It should be a blue wire you should be able to see once you remove the covers of the colomn.
