My suburban was wrecked last fall (rear ended

Not that I know of. But remove one cable, and put a test light across the gap. If it lights, you have a constant drain. Then remove fuses, etc. one at a time, until it goes out.

With accidents, it is common for wires to get cut, insulation opened, alternators to get burned out by a short, etc.
So it also would not hurt to put a voltmeter across the battery to check the alternator output.
The idea is it has to be about 12.5 idle, and over 13.5 at high RPM.

Changed fuel filter and now it wont start,,,how

You may have air in the injecter pump.You need to crack the lines loose at the top of the injecters.Just loosen as many as you can reatch.Back them off about 1-1 1/2 turns of the nut.Crank until you see the dielel squirting out without bubbles and re-tighten them individualy as the air is bleed out.When changing fuel filters try and fill them with disel as high as you can and then try to manualy prime the system while opening the bleeder valves.Well hope this helps and good luck.

Stater cranks over and will not start had celonoid

The starter is doing its job if motor is turning. To fire an engine you need fuel and spark, You can remove a fuel line near the delivery to the intake, get a gas proof container, like a mayo jar, and try key for a few seconds, fuel should come out pretty good.
To check spark, remove one spark plug wire, put within 1/4 inch of some metal around engine (I don't recommend holding on to it) Try key again, you should see a blue colored spark jumping to metal. It usually makes a zapping sound.
If you have fuel and spark then it becomes a timing issue and in some instances a compression issue. At this point you have to have more automotive knowledge to figure it out. Good luck!

How to replace the high beam bulb on a 98 GMC

Headlamp Bulb: Service and Repair
REMOVAL PROCEDURE
1. Make sure the headlamp switch is in the OFF position.
CAUTION: Halogen bulbs contain gas under pressure. Handling a bulb improperly could cause it to shatter into flying glass fragments.
To help avoid personal injury:
- Turn off the lamp switch and allow the bulb to cool before changing the bulb. Leave the lamp switch off until the bulb change is
complete
- Always wear eye protection when changing a halogen bulb.
- Handle the bulb only by its base. Avoid touching the glass.
- Do not drop or scratch the bulb.
- Keep dirt and moisture off the bulb.
- Place the used bulb in the new bulb's carton and dispose of it properly.
- Keep halogen bulbs out of the reach of children
NOTE
: Avoid touching the bulb or letting the bulb come in contact with anything damp. Oil from your skin or moisture on the bulb can cause
the bulb to explode when the bulb is turned on. It either comes in contact with the bulb, clean the bulb with alcohol or a suitable degreaser and
wipe the bulb dry.
2. Remove the bulbs from the headlamp capsules by reaching from the engine compartment and by twisting the bulb counterclockwise.
3. Remove the 2 long screws from the top of the radiator support.
4. Pull forward the headlamp assembly (3).
5. Disconnect the electrical connector (2) from the burned out bulb assembly (1).
INSTALLATION PROCEDURE
IMPORTANT
:
- Replace a high beam bulb with another high beam bulb. The high beam bulb has a red gasket.
- Replace a low beam bulb with another low beam bulb. The low beam bulb has a gray tip and a yellow gasket at the base.
1. Install the new bulb assembly (1) into the headlamp assembly (3).
Twist clockwise the bulb assembly.
2. Seat the bulb assembly with the connector facing down.
3. Connect the electrical connector (2) to the bulb assembly.
4. Install the headlamp assembly.
5. Install the 2 long screws through the top of the radiator support.
6. Tighten the screws.
