How do I Troubleshoot a 1990 GM Truck That Wont Start

General Motors makes a wide variety of trucks for the consumer, but all of them rely on gas and a battery to start. If you are having problems starting your GM truck, you can troubleshoot the problem by taking a look at these two components. When your battery has a low charge or is dead, the trucks motor will not be able to fire up. GM trucks require gasoline to run, so a low fuel tank could be the culprit to your truck not starting.

Instructions

1

Turn the key in your GM truck to get the gauge readings. Check the fuel level and make sure you have enough fuel to start the truck. Add fuel if needed.

2

Pop the hood on the GM truck and locate the battery. Use a socket wrench to disconnect the battery terminals from the battery. Clean the battery terminals with a wire brush and a can of soda if corrosion has set in.

3

Reattach the battery terminals to the battery and start the truck.

4

Jump start the truck with jumper wires and another vehicle. Allow the truck to run for about five minutes and then turn it off.

5

Try to restart the truck. If the truck doesnt restart, you will need to replace your battery.
