The following guide will teach you how to troubleshoot a 1994 Chevy S10 Blazer so that you can confidently assess problems on your own, using some basic automotive tools. You can find the necessary tools a local auto parts dealer. This task will take you about a half hour to complete.
Assess the issue. Try to charge the battery and attempt to crank the truck. If the battery is out of energy, the starter will not turn over.
Listen closely for any strange noises coming from the truck while it is running, such as clunking or a squeal. Normally, brakes will squeal when they are worn down. If they are beyond simple maintenance, they will make a clunking sound. If your fan belt is worn or moist it will make a squealing sound indicating that the part needs to be replaced.
Search for leaks. You will need a flashlight to check thoroughly from many different angles. Some leaks are difficult to pinpoint without a light source. A red fluid that smells sweet means that the transmission is having a problem. An oil smell and a dark brown or a black-looking leak indicates that the engine oil may be leaking. If your coolant is escaping you will see green, yellow or even red, but it will not be oily or sweet-smelling. A gas leak can usually be detected by the trademark gasoline smell.
Look at the dash lights to be sure that the engine or service lights are not on. These lights mean that there is a mechanical motor problem. Scanning the truck computer for stored engine codes can help to find the source of the problem.
