No start condition even after I replaced my battery. Well today I was giving a repair order with one concern. Customer states "after replacing battery car still doesn't start at times and sometimes takes longer than usual." Well this was an easy repair the 1st thing I did was check the terminal's for looseness or damage like cracks, corrosion, and if the ground cable that connects to the body was not being interrupted by an outside source. As soon as I grabbed the the positive terminal and then checked the negative I found that both terminals were left loose by whoever replaced the battery. After I tightened the cables I ran a battery and charging system test which everything passed.
Something so small like that is overlooked all the time. So take your time and pay close attention to what you are doing and you won't have these issues.
Here are a couple things I would like to help people doing research on vehicle repairs. So for those with no idea on where to start or what symptom's to look for when your vehicle is not starting often and you have to start your car by jumping it every couple of days or everyday.
First thing for you to know is there are only 3 things that will keep your vehicle from starting. The 1st is Fuel. You need gas to start every car. The 2nd is air to mix with the fuel which creates combustion. The 3rd is spark you need power to spark the "spark plugs" which burn the Fuel/Air mixture.
The fastest and easiest way to verify if you are having a lack of, or too much fuel issue which is causing your car to take a longer period of time to start or floods out the spark plugs to the point of a No Start. Look for the fuel rail which is usually found near the intake manifold. Most vehicles have a nozzle like tip (looks like a valve stem) If you have someone with you have them crank the vehicle while you push that nozzle in you should get fuel to come out very pressurized. Which eliminates your fuel issue as far as fuel pump.
The 2nd important ingredient in this soup of combustion is Air. Make sure your air filter is clean of debris and your throttle body is open which lets all air into the engine. The air is measured by the Maf sensor (Mass Air Flow) which measures the volume and temperatures' of the air the vehicle is taking in from outside. Fuel/Air mixture is read by the Maf sensor and fuel pressure regulator. If you have a Maf sensor that is going bad on you your car might not start. Some vehicles SOME vehicle are designed to run in SAFE mode and wont run well but will start at times. At that point you have an idea that your Maf is bad. Replace it and eliminate the air issue.
The 3rd and most important is ELECTRICITY. No power means No start. If you go to your car and you don't get a click or a very slow crank but turns on. 99% chance your battery is going bad. If you get a jump and the vehicle stays running then you can eliminate the charging system because the ALTERNATOR is generating power to the battery. Batteries usually last 3 years or so 60,000 miles. At times the internal cells in the battery go bad. I will go into details about batteries and the internals on another day. If your battery is good and you think your starter is bad. The easiest way to check if your starter is getting power is by the headlights dimming while cranking. If the starter is sticking you will hear a jammed noise like a click click noise.
Hope this was helpful. Leave me questions on your concerns.
