It may not be the alternator causing the vibration - it could be something else being driven by that belt. I would take off the belt and check the idler pulley first, then the rest to see if there is a misaligned pulley or one of them is very rough or loose when being manually turned.

Found these two fuses for hvac. Use a test light, check voltage on fuse circuit, key on. Yes, the ignition switch is involved. Check feed to ignition switch, both show to be red wires, hot all the time. The feed from ignition switch to hvac shows to be orange wire.

Blue - oil is being burnt - rings , valve seals , Black - running rich , leaking fuel injectors . leaking fuel pressure regulator . Smokes from were , exhaust ? Engine bay etc....

Have you had any issues with your oil level raising? You could have an injector sticking open slightly letting the residual fuel pressure that is in the line bleed fuel into the engine after shutting the engine off.

there are several sensors including the VSS, TCM, vacuum actuator oil pressure and ECM
the idea is to read the fault codes to show the problem units

Backfiring is usually associated with a lean condition. Is fuel pressure correct? Is this vehicle TBI and are both injectors working properly? If timing related it should spark rattle under load and the timing would be way out and not run/start well at idle

Go to LMC late model cars an trucks. They have all the parts for your truck with diagrams. Down load the correct catalog an you can see all that is needed. As well you can go to this link an read this article about it on an older truck. I understand they are simular in design.

Need to verify air, fuel, ignition, and computer codes.
Is there a fuse blown or bad wire connection on battery, alternator, or grounds to frame?
For TBI ( Throttle Body Injection ) systems, is the check engine or Service Engine Soon light on or had come on?
That will most of the time tell you by the code what electrical computer sensor or component is faulty.
I recommend the Haynes Repair Manual for your specific year range of make and model. There are more trouble shooting helps and test with computer codes too.
When there are no codes in computer, check the MAP sensor vacuum line and connector; TPS sensor; distributor cap and rotor, spark plug wires, spark plugs and the spray pattern from the TBI injectors ( when engine is running ).
When was the last time the fuel filter ( usually mounted on the inside of the driver's side frame rail ) was changed?

Replace ballast resistor.

That could be a perfect reason to take it back to the shop where it was just repaired for repeat service. Either that or you spun out in the mud.
