Hello and welcome!My name isCustomerand I can assist you with your question.
If the engine starts each time with a jump, then this is usually a bad battery or a bad connection at the battery.
Sometimes the starter can work intermittantly and cause a no crank condition but work just fine when it is being tested so there may not be any hint of a bad starter. So the best way to diagnose this condition is to check the battery voltage and the voltage down at the starter with the key in the CRANK position when this no crank condition occurs.
I understand that sir.
I am saying that they go bad intermittantly and may have tested out ok, but can still be bad causing this intermittant no crank.
In addition, we are checking for voltage down at the starter. This will ensure the integrity of the starting circuit.
Now, the question is why would it start each time when you jumped it?
There could be two reasons. Either it is something related to a low voltage situation (battery or connection issue) or it is simply a coincidence. Because it might be something un related (starter relay, connection issue possibly PCM) but just happen to start working again at the same time when you jumped the vehicle.
Keep in mind, we can even speak on the phone if you would like.
I have to log off line for a bit. I will send over a premium offer with my phone number. If you would like, you can accept my offer and call me so we can talk more in detail about this. I will be back on line in about 1 hour.
You would use a test light or a voltmeter to check for voltage on the big and small wire going to the starter while an assistant turns the key to the CRANK position.
You are most welcome.
I will be here if you have any further questions.
