That “spike” is called INDUCTIVE KICKBACK and it’s often prevented by adding a reversed bias flyback diode. Pinball machines are notorious for blowing the transistors that drive the coils in the game... same reason.
FORD knew the 2002 F150 had bad DPFE sensors. Their solution was to cancel the sensor from setting a code. But these faulty DPFE would open the EGR valve while engine was too cold to handle it. Lean condition would ensue and the spark would not ionize so the COP sought an easier path internally and fry itself. Nice, real nice. I went through a bunch of them. Took me a while to connect those two things together.
EGR does not cause a lean condition. Exhaust is an inert gas and therefore cannot possibly lean out a mixture. If anything it can enrich the mixture somewhat. EGR does cause a misfire, but that leads to unburned fuel. Unburned fuel has low electrical resistance and the coil will not need to work hard to fire those plugs.
@silverbird58 Today's emission and fuel economy rules would never allow points and condenser. They're too inefficient and inaccurate for timing control. And Points needed to be replaced every 12-15K miles. Modern systems are mostly trouble-free for 100K miles.
I'm trying to buy a Toyota Corolla 5 speed 4 cylinder 1996 model my friend says that the coil pack keeps shorting out every time he changes it,in minutes. What causes this and how do I fix it?
my 2wire coil pack wires were reversed.wires just hanging out .dont know which wire goes to which pin.please help solve..can this blow coils.they are brand new
So my coil melting twice could be coused by my old spark plugs right. I have a 3.6 liter GM it's in a 09 Buick Enclave number 3 has melted twice on me . first time it about cought my Buick on fire. Can you help please
got a question, we have a 1998 c3500 sivrado, big block coil has melted, guts melted out of epoxy, like a ball of snot. what can cause the coil to melt out? any response would be great, grounds on motor check out ok to battery and the engine to frame ok, one of the guys thinks it is a dist going bad?? any experience would help.
I have a 2005 Pontiac Vibe. I have had the same coil pack die three times in the last 4 years. I replaced the plugs about 2 years ago and the Vibe doesn’t have a wire set. Does anyone have an idea why that might be happening?
What did the plug look like when you pulled it out? Where is your engine ground located, and is it in good shape? Is there anything near that coil (exhaust manifold, etc) that could cause it to overheat while it operates? If the problem isn't related to one of those three things, I'd start to look upstream at the ignition control electronics. Maybe they are damaged and passing excessive voltage to the coil. It may be economical for you to simply buy a new coil pack every once in a while from RockAuto and DIY replace as needed.
Hey would you have any idea why my Pontiac G3 keeps blowing coil packs.gone threw 3.one lasted a 100.miles replaced thinking it was faulty.the second one lasted about a 1000 miles.please any advice
They just go bad on they're own. If one goes it's good to just replace all because they could go in days weeks or months but eventually will go. Just buy all of them and change them as they go
Strange Person! xP u found the solution?? Bcoz i have the samme problem in my honda civic 2006 when is come load coil pack is going...in couple of hours...i change alot but the problem is same...
I have battery voltage ground signal and low ref going to my coils but no spark what would cause that 🤯 is it possible for all my coils to burn up at once 😬
you seem to know your stuff but.............VERY Suprised you failed to mention prolly the #1 REASON for coil failure............. oil leaking into spark plug tubes from bad spark plug tube seals!!!! dam how could you miss that???? maybe trying to sell more coils for your company instead of simply and cheaply changing bad tube seals??? hmmmmmm..................
I have infinite FX35 2008 Always it burns the ignition coil They check everything but no sussed... Before all this thing start . the car burned the ECU then i ordered original one ... and every thing gose ok . But now the coil ignition start to burn every 5 month Please advise
@Sam S Many thanks Sam... Could you please help me in other thing If you have harness electric wire diagrams send it to me... i spend to much money on this car
Sounds like a short in a/c somewhere and it’s back feeding or your alternator may not be strong enough to run it all, so when you turn it on it pulls the motor and voltage down to far
number one COP coils going bad is the new engines run too lean its something that we can not do any thing about but hay just think its great for us keeps us in a job
Delphi coils will fail even if you don't drop them from my experience. Fancy Chinese junk. Bosch is making junk also now. Eldor is the only quality ignition coil for now.

Thanks for this. Explains why my coils are failing one by one right after I changed my 230,000 mile plugs and wires on my Avalanche.

@@davidbsac Faulty DPFE was causing an open EGR. That is unmetered air and can cause a lean condition.

Hi my nissan sentra 2010 keeps burning out coil pack #2 new plugs new coils . Could the ignition control module in the computer because in this ?
so how do we prevent corrosion on the plug connector.
what should we apply on the contact point?
Dielectric Grease my friend
I have a 01 626 Mazda put it in neutral stay running put it in reverse or drive cuts off could it be my coil packs going bad
On going problem with my sisters suzuki swift...very information video
I'm trying to buy a Toyota Corolla 5 speed 4 cylinder 1996 model my friend says that the coil pack keeps shorting out every time he changes it,in minutes. What causes this and how do I fix it?
Same with my 09 Buick Enclave . # 3 coil has melted twice . vo tech teacher says it might be the ecm .
Could be ecm or I had one doing the same thing and I changed my connectors that plug into the coil and it fixed it
my 2wire coil pack wires were reversed.wires just hanging out .dont know which wire goes to which pin.please help solve..can this blow coils.they are brand new
Shall i change my sparkplugs when replacing my coil pack?
Adam.43 yes
Just look at your spark plugs if they are burned or not
Best on RUclips

What did you do to fix? Same happened to my 09 Traverse. Now it won’t start 😮
@@zkqg Replace all of the spark plugs when you change a coil. Plugs are mad cheap.

Same thing that's happening with my 09 Buick Enclave 3.6liter
Check your alternator may be over charging or also a short in it. May also check the actual plug that plugs into the coil pack

I just installed 6 coils on my 2003 bmw and the coils not making contact with the spark plug please help
ok..so what would cause all 6 coil packs to go at once? code of 0300 on all 6 cylinders with cel now flashing.
They just go bad on they're own. If one goes it's good to just replace all because they could go in days weeks or months but eventually will go. Just buy all of them and change them as they go
@@mwfrost3427 i think he said they all went at same time..
Check spark module that the coils sit on can’t think of the name of it, pickup coil or something
Is it possible to repair the death coil?
They have remanufactured OEM coils.
I have this problem with my Vauxhal Astra G 1999. I change the ignition pack but the problem comes back after a couple of months.
Strange Person! xP u found the solution?? Bcoz i have the samme problem in my honda civic 2006 when is come load coil pack is going...in couple of hours...i change alot but the problem is same...

Oil causes misfire conditions but rarely causes a coil to fail. If anything the coil isn't working as hard when the tube fills with oil.
Nice. Subscribed.
Thx man.. that was some recoil!
wowwwwwwwwwwwwwwwwwwwww what a great video thanks once again it was so helpful

I have a Ford edge 2010...is burning out my ignition coil for 2nd time ..what is the cause and I need to replace control module?
same things happened to me this is the 3rd one!
Did u use dielectric grease? Arcing maybe?
I have infinite FX35 2008
Always it burns the ignition coil
They check everything but no sussed...
Before all this thing start . the car burned the ECU then i ordered original one ... and every thing gose ok .
But now the coil ignition start to burn every 5 month
Please advise

@Sam S
Please please 🙏🙏
Was told be teacher at tech school my ecm was bad I haven't changed it yet guess I better put new plugs in then start all over again .
I have same problem same engine, but mine happened after a few minutes, what did you do?
I have a 2003 Mitsubishi eclipse that burns the coils when I use the the ac on the car. does anyone know what could cause this?
sounds like a short. follow ac wires and see if they go with the coil wires
Sounds like a short in a/c somewhere and it’s back feeding or your alternator may not be strong enough to run it all, so when you turn it on it pulls the motor and voltage down to far
I got a Honda accord ex v6 99 crank and it won't start up I got new distributor cap and spark plugs wire new rotors and nothing and no spark
jjsnoopy7 check the main relay of fuel pump
+Junito Amadeo thanks but I fixed it already it was the ignition coil
jjsnoopy7 good 💪
Everything about a vehicle engine now days sucks
I love the coil.
Thoughout oil to the plug
Sounds simple so I need to replace plugs gap them replace coils and wires and see what happens
number one COP coils going bad is the new engines run too lean its something that we can not do any thing about but hay just think its great for us keeps us in a job
Not me . Definitely not friends
I’m ordereing freshies tonight
Do bad coils make a car sputter real bad?
Yes because it delivers the spark to the plug and if it’s not send the right amount of spark it will misfire or not fire hot enough
Delphi coils will fail even if you don't drop them from my experience. Fancy Chinese junk. Bosch is making junk also now. Eldor is the only quality ignition coil for now.
U will be cursed constantly
