I had the same thing happen when my battery terminal was loose; it killed the alternator, so the battery doesn't get charged. There are cheapo battery/charging system testers that plug into the socket, or your local auto parts store often offer free testing of the alternator and battery.

SOURCE: 4 wheel drive service light is on, wont engage

On the full size, the front actuator is electric, not vacuum.

When in 4wd mode, a switch on top of the transfer case conducts 12 volts out to the actuator. Wire #50 (brown) is the 12v feed, and it conducts to the light blue wire (#900) to the actuator.
When shifted out of 4wd, the switch opens up and no voltage goes to the actuator.

Check voltage at the connector for the front actuator (at the front differential - it looks like a large bullet that threads into the front diff.) If it has 12 volts, the actuator is the problem. If it does not have 12 volts, check the transfer case switch and the power feed to the transfer case.

I'll assume it is the actuator, if the plug to the actuator is getting 12 volts when in 4wd.
The way this actuator works, is it is a sealed chamber that gets heated by voltage. When it heats, the pin in the end swells and pushes a shift fork in the front differential. The shift fork engages a spline on the passenger side of the differential, and boom! you have 4WD.

GM offered an upgrade to this actuator that is a motor instead of a heated device. However, it requires a small harness addition, a spacer, and a new actuator. It is about a $150 to $200 option.

If I were you, I would buy a new heated actuator. They are available at most auto parts stores, and are about $90. They are also on eBay for about $55 plus shipping. These are very easy to change - just thread out the old one, and thread in a new one.

Good luck, That actuator is usually the problem 90% of time but check the fuse first in your fuse box.

No spark from coil to distrubuter


Disconnect the ignition coil output wire at the distributor cap.
Connect a spark plug to the end of the ignition coil output wire which you just disconnected.
Connect a ground wire to the threaded portion of the spark plug.
Disconnect the ignition coil ground wire from the negative terminal on the coil (Green Wire).
Connect one end of a ground wire to the ignition coil negative terminal.
Turn the ignition switch to the ON position.
Tap the other end of the ignition coil ground wire jumper on an good grounding point (for example the battery negative terminal) and look for sparks at the spark plug that correspond to the frequency of your tapping of the ground wire.
If you have a good spark at the spark plug, the ignition coil is good.
If you don't get a good spark, check for approximately 12 VDC from the coil positive terminal (black wire) to ground with the ignition switch in the ON position. You should also get approximately 12 VDC from the coil negative terminal (Green wire) to ground
Ignition Coil Resistance Check

In addition to the test above, you may elect to perform an ignition coil resistance check as confirmation of the coil's condition.

Check the ignition coil primary coil resistance by connecting an ohmmeter between the positive (Black wire) and negative (Green wire) terminals on the coil. The resistance should be 0.4 to 0.6 ohms.
Check the ignition coil secondary coil resistance by connecting an ohmmeter between the coil output terminal and the ignition coil negative terminal. The resistance should be 5000 to 7200 ohms.

You may have a bad coil or bad ground or wire connection

Sounds like a bad ground, jump a wire from negative batt terminal to a good bare metal spot on the bed of the truck, (where the latch grabs is one of my favorite spots) if all starts to work you need to ground the bed, if not time to check for power(fuses,connections, poorly installed trailer light connector) let us know what you find!

you dont have a good enough connection from the battery to the ground or the live wire on the battery is a weak connection.. Run a new wire from the negative side of the battery and attach it to the body somewhere to a nut but bare the paint to do so and clean the bolt so you get good contact, can also run a wire to a bolt on the engine. Also check the connections to the battery both positive and neg and clean the battery terminals and cable terminals. A corroded terminal reduces cranking power by 80 percent.

It's electrical.And won't start


I would have the alternator checked at any of the chain auto parts stores who will do it free.
I would also, while there, buy a battery terminal cleaner (~$3 US) remove first the negative terminal, cleaning clamp and post, then remove the positive terminal and do the same. If you still have signs of bad connections, you may have to remove and clean the other ends of the battery cables (dirty job) and always remember to remove the negative lead from the battery first otherwise you run the risk of slipping with a tool and shorting the positive terminal to ground which will make neat fireworks even if it isn't Independence Day.

Was running fine and acted like it ran out of gas. will not start has gas and fuel pump is priming.


it di it did run out of gas your fuel filter is likely pluged full of **** and it aint going to the motor
to find out if im right find your fuel rail and try bleedijng it there is usualy a schrader valve for the teck to hook to for a clean out if the fuel doesnt come out when you push the inner pin down on the schrader valve then you have your problem

it also might be a good idea the make sure your fuel pump is working
ie: can you hear the pump in the tank?

Make sure the battery terminals are tight. These cars have a double stacked positive side terminal that, to get tight enough, usually means stripping the threads on the battery. After fighting with this connection for more than a year, I finally put an old fashioned post adapter on the positive threaded side terminal, then put another 'marine' adapter on the post. After stripping the rubber insulation off the two positive wire's terminals, they'll stack up on the marine post and wing nut them good and tight.
