Why Does My Car Start Sometimes And Not Others

Sometimes when i try to start my car, it doesn't seem to catch. No fuel supply because of a faulty fuel pump, bad fuel pump relay, blown fuel pump fuse, plugged fuel filter or line, or failed ecm injector driver circuit or injector power supply relay.

In that case, you might hear a repeated clicking sound that can come from the engine compartment;

Why does my car start sometimes and not others. I took it to my mechanic and he could not find any issue or recreate the issue. First, if the van cranks over we can rule out the starter, battery and starter relay. In fact, battery problems were the cause in over half of the cases (55%) where our patrols were called out to a car that wouldn’t start.*.

Given that yours will start sometimes but not other leaves a few possible causes. When it will not everything inside the car turns on but the engine itself wont start. If the lights dim in your car, (but not considerably) that probably means that your starter is getting power and the ignition works

Assuming the van cranks over you will want to be sure the engine has. Get them cleaned and tightened. Turning the key turned on all electronics and i could hear what i believe to be something in the fuel system spinning as i attempted to start the car.

In this case, you may suspect worn out plugs or low fuel pressure. Sometimes my kia wont start. If that does not fix it, then you may well have either a defective starter, or a worn out ignition sw.

The alternator’s job is to keep the battery charged and evidently its doing its job. The first thing to have your automotive buddy check dear are the battery posts and lugs. I may not drive for a couple days and it will cool again.

This sound will relate to a dead battery or a faulty solenoid. It just happened again this morning and when i went out to check it an hour ago it now started this time. There are a few ways your battery might go flat or even die:

If the vehicle will crank sometimes and others it will not, you may have a faulty starter. Dont overthink this one, it is a common problem. The most likely causes would include a fault with the ignition switch, battery cables, fuel pump, starter, or low fuel pressure.

If the battery has plenty of power to turn the motor over for a while, it’s definitely not the alternator. Lastly, if your car starts intermittently, your car will sometimes start, and sometimes it doesn’t. It seems to work when it wants to but it does seem to stop cooling if i've been out driving a couple hours.

That is why it pays to have a qualified shop diagnose the causes instead of just throwing new parts at. (or poor connections at one of these parts). If it does not crank over and simply makes a clicking sound, i would suggest checking the starter relay as this is a common issue which will produce a clicking sound even when the battery and alternator are good.

I replaced the battery, so that is not the issue. This only happens sometimes, and when i took it to the shop, they couldn't find anything wrong. A few days ago my 2003 honda accord would not start.

Why does my air conditioner only work sometimes (intermittently) in my 2000 toyota tacoma prerunner? It stopped working last summer and a few days later it was cooling again. The battery’s usually the main culprit behind issues with starting your car.

The classic trouble guide says the engine needs spark, air and fuel to fire off when i. Third, suppose your car starts intermittently, and you have a starter solenoid issue. Try jumpstarting the car when its not working (if it works, you can cross off the battery as a possible problem) also make sure battery cables/ground have good connection and arent corroded;

Flat, faulty or dead battery. Consider hiring an experienced technician, such as one from yourmechanic, to come to your home or business and determine if you have need spark plugs or a starter replaced. I called aaa to have them tow the car.

If it cranks normally, and doesnt start, the reason maybe no spark because of a faulty ignition circuit. Top reasons why cars won’t start.
