Car Troubleshooting in a Nutshell
Whenever you’re troubleshooting a car problem, it’s best to be methodical. You can analyze pretty much any problem with a good multimeter, though there are also a number of smartphone apps you might try as well. A fuel pressure gauge is also a good idea to test your fuel gauge. If you turn the key and nothing happens, no engine, not even the lights come on, then chances are you’ve got an electrical problem. Check the battery posts and cables. Try whacking it with your shoe to see if you can re-establish a connection. Some problems will intersect, so it can be difficult sometimes to find the root cause. And remember to be patient. Frustration is where you often make the most mistakes.
