First check your basics. Check the fuel filter for plugging. It is on the driver's side of the frame underneath the vehicle. The other item to check is the MAF or mass air flow sensor. If there is a check engine light on have it scanned by a local auto parts store for free and let me know what the codes are. Be happy to help further.

you could be dealing with a vacuum leak on the manifold. you can use some wd-40 or carb spray to help find it. just spray it over the hoses and if there is a leak you should here a change in the motor.

Try checking the connection at the blower motor its likely the problem

You set number one piston at Top Dead Center (TDC) and made marks on the distributor in relation to its location on the engine, or at least remember the direction in which the rotor was pointing. If you didn't, then the first thing to do is set TDC and then stab the distributor. At TDC, the rotor points to the number one spark plug wire post, follow the firing order from there. While stabbing, you may have to rotate the distributor left or right a little to get the splines to mesh.

Could be a bad ground oh headlights or power not getting to the bulb hot side.
If you have a volt meter you can measure the voltage there on the headlamp.
First measure the hot side...if 12 volts there then measure the bulb ground side. If 12 v is there then the ground connection is bad.

Hope this helps you

It would help to know exactly what the voltmeter was reading.
Although many US trucks have ammeters instead of voltermeters, which are not as useful.
If you are saying the ignition switch is not causing a heavy draw as one would expect from a starter, then either the ignition switch, neutral safety switch, solenoid, bad engine ground, or dirty battery terminals are reducing current flow. A voltmeter should read 12 volts from the battery when engine is off. Why you try to start, the starter should draw it down do about 10, but then when it starts and you rev it up, it should go over 13.5. If it does not drop to 10, then you have a blockage.

This would be a loss of freon in the system, provided that you know the blend door is operating. You can have a local mechanic recharge the system and add dye to find a leak. Leaks are often bad O-rings but can also be bad mating surfaces on components.

unfortunately these trannys are all electronic with no adjustment, you will have to get it rebuilt, repaired, or replaced unfortunately..

a leaking fuel injector will continue to flow fuel after the engine is shut off. This fuel flows down the cylinder wall, past the rings and into the oil pan. A leaking fuel pressure regulator will do the same.
