What was the problem with the ignition coil?
Ended up at dealer, $600 and some coil packs later she took off, running smooth. Less than 30 minutes later, car dies again in fast moving traffic. Car gets towed back, dealer puts 5 of their best on it, three hours later they Dx a bad ECU.
How much does it cost to fix an ignition coil?
Less than 30 minutes later, car dies again in fast moving traffic. Car gets towed back, dealer puts 5 of their best on it, three hours later they Dx a bad ECU. The good news is that the lead on this repair has the hots for the friend, so he offers a great deal: Parts at cost, minimal labor. New estimate = $1,200.
What are the voltages on the ignition coil?
I plugged in power cable to ECU, and found voltages on pins 60, 61, 62, 79, 80 and 81, similar to voltages I found at the coil pack connector. The ECU is trash, so I pried it open being careful to cut away the silicone sealant so I didn’t have to pry too much.
Why does my ignition coil keep burning out?
Here is why! The leading cause of premature failure of an ignition coil is due to a worn or bad spark plug ignition cable. A bad spark plug ignition cable will have a much higher than normal resistance.
What causes a spark plug to melt an ignition coil?
A bad spark plug ignition cable will have a much higher than normal resistance. This high resistance causes a very high amount of voltage to be generated from your ignition coil’s secondary winding. This excessive voltage creates a high amount of heat which consequently melts the coil’s wire insulation.
Why does my spark plug keep burning out?
A bad spark plug ignition cable will have a much higher than normal resistance. This high resistance causes a very high amount of voltage to be generated from your ignition coil’s secondary winding.
What is the diagnostic code for a bad ignition coil?
You can also do this yourself with an OBD-II scanner, which you can purchase online or from a local auto parts store. The possible standard diagnostic trouble codes (DTCs) are P0300 through P0312, which are codes for a detected misfiring. Codes P0350 to P0362 are reserved for ignition coil circuit malfunctions.
What are the symptoms of a bad ignition relay?
Fortunately, a number of symptoms can tell you beforehand if there is a problem waiting to happen or if it has already happened. We will now look into the signs of a failing ignition relay in detail. 1. Ignition is Unresponsive The ignition relay’s primary job is to help you start the car.

Why are the ignition coils on my Nissan Quest not working?
Van stopped on road and would not restart. Burning electrical smell was coming from the engine while trying to restart. Took the vehicle to the a dealer for repair and they found the coils and ECU burned out due to short in the ground wire. Repair cost $3200.
Why does the ignition coil keep burning down?
I didn’t check #1 and #3 because intake is still in place. Fluctuating voltages are good, but signal voltage is 0.4 at high signal, so each one is continuously firing the coil pack and melting them down. I also checked the ECU to make sure it had proper voltage, It had 12V on cable at pins 119, 120 and 7v at pin 109.
