The wire for the secondary on that particular circuit has to be tested If you have a ICM that secondary has to be tested there, If it is controlled from ECM it has to be tested at the ECM, because its a secondary wire it is capable of shorting the ICM or ECM it self, you only listed the year and.no engine size.

Ouch! A case of the raucous rodent! I've been there...Not fun trying to track down and repair all the damage.

First of all, let me explain how the code sets: The computer monitors the PRIMARY side of the coil to determine the burn time on the SECONDARY side of the coil. This can be a little confusing. The code will set when the computer determines that secondary ionization (burn time) was too short, too long, or did not occur at all.
If you have confirmed that there is no spark at the spark plug wires, then that is why the code is setting...ionization is not occurring at all. What can be a little confusing is that this can be caused by a failure in the PRIMARY coil circuit even though the code is indicating that the computer is having a problem with the SECONDARY circuit. (The secondary circuit can malfunction even though the primary side is functioning perfectly, but if the primary side malfunctions, the secondary side ALSO malfunctions - it is impossible for the secondary side to work if the primary side is not working.)

So, I said all that to tell you this: I think you have pretty much eliminated the entire secondary side of the ignition by replacing the whole circuit. So the problem must be on the primary side. (Probably more chewed wires)
There are 4 wires going to your ignition coil. The BROWN/WHITE wire comes from the ASD RElay and supplies battery voltage to the coil assembly. Since the other four cylinders are firing, This wire has to be OK.
The code you are getting is for coil #2. This coil is controlled by computer through the DARK BLUE/TAN wire. If you disconnect your coil connector and probe this wire with a test light connected to the POSITIVE battery post, it should "blink" when to crank the engine over. My guess is that it will not be blinking. You can do this also on the BROWN/ORANGE (coil #1) wire and the DARK BLUE/DARK GREEN (coil #3) wire to see the difference.

Anyway, if the DARK BLUE/TAN wire does not blink, then the wire is broken (chewed?) between the coil and the PCM.

How do I fix my v6 Camry the turning but would run I change coil ,cam and crankshaft sensors still wouldn't start


What was the original problem?

Did you look at Scan Tool Data?

Did you do any testing?
If not--- you found no problem
So why change any parts?

Who changed those parts-- a repair shop

Did you check for OBD Codes & look them up,
to see the possible issues?

OBD Codes have nothing to do with parts replacement

They are used to diagnose the system that set the codes
& then you have to component test to find a problem

Kept having cam shaft censor code, replaced it 5 times nothing changed, changed plugs and wires to discover #2 plug was all corroded,should we replace the power pack


I would replace all plugs first and see how it runs. If it has a miss, then I would start switching coil packs from another plug onto the #2 plug and see if the miss follows the coil pack. If so, then replace it. It the coil looks burnt at all, replace it immediately.

2003 neon not firing


could be many things, why did you change the starter? was it cranking the engine? if so you didnt need to replace it. I suspect the ignition module or coil pack. BUT, is it turning over or nothing at all, if there is nothing at all I suspect the ignition wire {not battery wire} on the terminal on the starter., does the car have a security/anti theft system? See if you can get a code reader on it to give you an error code, then research the code, that may tell you something, tough one guys without seeing it. hope I was of some use. good luck.
ps, just for fun...check ALL your fuses.

2000 model laser when driving under hard accelleration engine developes a missfire and feels like it cuts out. Have changed cam and crank angle sensors also ignition leads and one coil.Still no...


Servicing as you call it has nothing to do with diagnosing
or finding & solving problems that happen every year or so

Those several parts you indicate where replaced, I assume
were done at a repair shop

In any case,my opinion based on the actual parts replaced
tells me little if any testing for component failure was done,
as the parts replacement & continuing problem bare out

Again oil changes & such & mileage have nothing to do with
actually road testing a vehicle with the owner along ,as you should
alway do,and having a scan tool along to look at & record your
misfire data

Long story short
You have to start over
Nothing has been found or accomplished so far

Maybe a different repair shop !!

People at home, as well as repair shops, see a sensor
code & throw parts at it,when the sensor is just doing
it's job & reporting an out of range condition

Only the most knowledgeable folks & also having factory
trouble charts to learn from & follow will find & resolve things

If one coil was replaced based on obd codes,then maybe a
different coil is the bad one

I have seen when my professional scan tool software did
not help & codes were all over the place, on fords

I have had to walk a new coil from cyl to cyl to find the bad one

Your missing the fact that nothing on any motor vehicle
gets changed, until you understand how it works & how
to component test.

Codes do no tell you what is wrong or that
something needs to be replaced

Codes are used to diagnose possible system
malfunctions,& you usually will need a trouble chart
to follow

You need to study OBD2 on the internet

04' Ram 1500, bad mis-fire. cust repl s/plugs. no help. Codes for coils #7 & 8 w/mis-fire. replaced coils & wire set. Better, but still P0300. Compression good


You still have random misfires (PO300)
You most likely replaced those coils that set a code, and those were not the one bad offender,spiking the computer module.
Take a new coil and put in a cylinder,no change, replace old coil and move new one to next cylinder. You can do that once or twice a day, if you have nothing else to do. You need a 90 degree day, to really get that solved,unless you have an ignition oscilloscope.
Never had a bad spark plug in 45 years.

2002 Buick LeSabre shows 3 trouble codes: p0404, p0410, AND P0300 .. Car lacks power... will operate pretty well between 1800 and 2400 RPM. Beyond 2400 RPM there is nothing, no response when accelerator...


P0300 is random engine misfiring. Could be several problems. My car had this and I replaced the plugs and plug wires. No change. Checked the three coil units. They seemed ok. I used a new on in each spot and nothing changed. Ended up being the ignition control module that sits under the coils. Relatively easy to change. Costs around $150 at the parts store. This may correct the other codes.
