My Chevrolet 7 4 Wont Run

The Chevrolet 7.4-liter engine is primarily used in Suburbans. When having problems with your 7.4, there are several things to do before taking it to a repair shop. Common issues include the battery, fuel and starter problems. You can diagnose these minor problems. However, a qualified mechanic should always perform major repairs.

Instructions

1

Turn the key in the ignition and listen for any sounds coming from the engine. If you hear "clicking" then a technician should test the alternator on a diagnostic machine.

2

Turn the ignition halfway to turn on the instrument panel. Look over the instrument panel to make sure you have enough fuel to start the engine (if not, add about 1 gallon of gas).

3

Open the hood of the vehicle and look over the battery connections. If you find the battery connections loose, tighten them with a pair of channel locks or pliers. Try to restart the car. If the car will not start, the charge might be low.

4

Use a voltmeter to test the battery. Connect the positive and negative leads of the voltmeter to the positive and negative leads on your battery. Look over the reading. If the reading is under 11 to 12 volts, you need to charge the battery.

5

Connect a battery charger to the positive and negative terminals on the battery. Plug the battery charger into an electrical outlet and let the unit sit for about 12 hours. Try to restart the vehicle after 12 hours. If the vehicle does not start, you need to replace the battery.

6

Get under the vehicle and look for the starter. The starter is a small black box on the right side of the engine. With the emergency brake engaged and the car in "Park," have a friend turn the ignition and listen for a "buzzing" noise coming from the starter. If you hear the buzzing, you need to have the starter replaced by a service technician.
