Why does my battery have intermittent starting difficulty?
If the battery has an intermittent inter-cell connector problem, the voltage will drop to very close to zero yet if the key is released the voltage will mysteriously go to nearly a full charge condition or whatever it was when the ground cable was reattached as mentioned earlier. I hope this is helpful.
Why does my Car start intermittently after starting?
A faulty alternator is typically intermittent, which would explain the intermittent issue you’ve described. Barring that, and assuming the battery and starter are indeed fine, I would next check the spark plugs and finally fuel injectors.
What should I do if my battery won’t start?
If you run into this type of problem a cheap voltmeter can become your best friend. If you have no starting current, check the “open circuit” (ground cable removed) from the battery and the voltage checked at the battery’s terminals. It will almost always be normal. Reconnect the ground cable and re-check the voltage.
Can a two year old battery die intermittently?
Clean the terminals, yes. Especially if they’re visibly corroded. It’s unlikely for a two year old battery do die intermittently; however, weirder things have happened. When a battery is intermittent, one of the plates inside is sloshing around, shorting out and not shorting out. Again, unlikely. The starter, however, might be the problem.

What causes a car to start intermittently?
Intermittent starting problems can be tough to diagnose. Starting problems with vehicles are almost always related to electrical or fuel delivery issues, but there are a lot of parts in these systems.

What should I do if my car battery is intermittent?
If it’s not the battery, be prepared, intermittent battery issues can be a pain to diagnose (and to live with). We had a stuck AC valve which would drain the battery in a night, but would only stick once a month or so…took forever to figure out.
What are the symptoms of a bad charging system?
Symptoms of a charging problem include a low battery, dim headlights, hard starting or a charging system warning light. Many parts stores have an alternator test stand and can test alternators to determine if they have failed or are capable of putting out their rated amp capacity.

Why does my car not start when I Turn on the ignition?
This is caused by a loss of voltage someplace in the electrical system. Most of the time this is caused by a bad connection at the battery or a bad battery cable. I usually check and clean these connections and see if there is anything that is loose, or if there is any corrosion. If these are fine, then it may be a failure in the fuse box.
Why does my truck not start on battery?
Symptoms: Truck will not start on battery power, and struggles to even run lights. Battery installed 8/2014, tests 12.4V static, not load tested yet. Truck has had intermittant no-start issue that has gradually gotten worse. As of yesterday, will NOT start on battery.
What to do if your Jeep Wrangler battery won’t start?
The first starting point when diagnosing a dead battery is to verify your battery has the correct voltage. Incorrect or low power to the starter will not start your Jeep. Batteries use CCA (Cold Cranking Amps) to measure starting power.
Why is my starter not getting enough power?
It might not be a main power wire, but instead it could be one of the smaller ones. (If you can’t get power to the circuits that energize the relays for the heavy loads like the starter, then it doesn’t matter if the heavy wires are okay or not.) You may need a better mechanic.
Is there a way to diagnose intermittent stalling?
Diagnosing an intermittent stalling problem can be a challenge, especially if the engine only stalls occasionally (and at the least opportune time). And if there are no pending codes, hard codes or history codes in the vehicle’s computer to give you some direction, you may find yourself guessing at a diagnosis.
Is there check engine light for intermittent stalling?
Many times, there will be no check engine light and no fault codes to give you a clue as to what might be causing the engine to stall. So the trick to diagnosing an intermittent stalling problem is to catch the vehicle when it’s acting up — and that rarely happens when you have the vehicle in your shop.

Why does intermittent stalling occur in a car?
One of the more unusual causes of intermittent stalling we’ve heard about is a defective vehicle speed sensor. When the vehicle stops moving, the PCM may not engage the idle speed motor (carbureted engines) or idle air bypass motor (fuel injected engines) so the engine will idle normally.
How can I tell if my car is stalling?
So the trick to diagnosing an intermittent stalling problem is to catch the vehicle when it’s acting up — and that rarely happens when you have the vehicle in your shop. You may have to keep the car and drive it for a few days to see if it stalls.
Is there a problem with the ignition key?
When you turn the ignition on, the red light should come on for a second then go out. If this happens, the car is happy with the key and you don’t have a car key problem.
Can a car start after hitting the start key?
You may hit the start key several times and magically the car starts and all is normal for an indeterminate time. Jumping may also result in the same phenomenon (all of a sudden all is fine syndrome).
When to know if your key fob battery is bad?
If you notice that your key remote does not unlock your car, lock your car, or start the engine for those with the automatic start button as early as it should, it’s probably time to replace the battery. 2. Multiple clicks needed to unlock the doors
You may hit the start key several times and magically the car starts and all is normal for an indeterminate time. Jumping may also result in the same phenomenon (all of a sudden all is fine syndrome).
In this case, it’s important that you contact a mechanic as soon as possible so they can determine what is causing the intermittent contact. In many cases an intermittent starting problem is linked to a bad wire connection that may become dirty due to exposure under the hood.
What are the symptoms of a bad starter relay?
Listed below are a few of the symptoms of a damaged or worn out starter relay. If you notice these warning signs, make sure you contact a local ASE certified mechanic to completely inspect your vehicle as these symptoms might indicate problems with other components. 1. Vehicle does not start
What are the symptoms of a bad key fob battery?
Symptoms of a Bad or Failing Key Fob Battery. 1 1. Reduced signal strength. Most of today’s fob keys will send a signal to the vehicle up to 50 feet in many cases. Many car, truck and SUV owners 2 2. Multiple clicks needed to unlock the doors. 3 3. The key fob does not work consistently.

Why does my Mercedes not start when I charge the battery?
This Mercedes-Benz is not starting because of a low battery. In this case, what you need to do is trickle charge your battery using any of these 12 volt battery trickle chargers. If you need help read this article on How to charge a Mercedes-Benz the right way. Mercedes won’t start, and it’s not the battery.
What does it mean when Your starter motor fails?
Starter motor failure produces one common symptom across all makes and models: When you turn the key, the starter solenoid will click, but the engine will not rotate. You also Read More
