I have a 2007 suzuki xl7 and only the front 3 cilinder are working the other 3 on the back they have no spark i replace the coils,and still the same


what engine, must be the V6, sure, the H27? engine
is car in usa, ?
the reason i need that INFO is spark systems very by COUNTRY.
you said coils, so that tells me its V6, and has 6 cops
6 coils over plugs. (unlike other engine in other countries)
so its like ours here. (or like the one I just sold, I now hate Suzuki)
they bugged out here, so are Yogo status to me:
(isuzu,suzuki,daewoo,yugo) dead dogs. all.
so what do we do, well that is easy.
we check fuses first. (we test the ones that look good)
or read the schematic on the H engine, in the book, and see which fuse runs IGN.
next we scan the PCM and the PCM sure can tell you problems.
XL7, 3.6L V6 in USA car.
ok, I logged in to mitchells for you.
and guess what, there are 2 fues
even coils
odd coils.

fuse 18 or 19, Im too lazy to look up which bank is even...
its just 2 fuses, so... moot point.

btw, we check fuses first on all electric fails
and spark is electric.
fuses that look bad, are in fact bad.
fuses that look good can in fact be bad.
we test them.
there are 2 tests (3 if ocd)
1: ohm check them. 0 good , infinity bad.\
2: key on check volts, 12v on both sides,of fuse good. if not , bad. (live tests never lie)

then the fuse blows again, after all that is its job to prevent fires on shorts.
so we have shorted COP.
3 fuses in hand find cop that is shorted.
1 cop plugged in at a time.

I use and ammeter, but I have tools.

Fuel pump


Testing of the fuel and ignition systems is in order. Intermittent problems need testing when the problem is present, otherwise it won't help find the problem.
I would start by checking for spark on a spark plug wire (or two or three plug wires, in case it may be a bad coil), during those times when it won't start. You need to see a blue, snapping spark to verify ignition system is working.
To check the fuel system, have the fuel pressure checked, and the injector circuit checked. Good that you hear the pump, but you don't know if fuel pressure is correct, or if fuel is getting into the cylinders. One short test is to spray starting fluid or carb cleaner into the intake while engine is cranking. If engine fires up for a few seconds, you know it is a gas related problem.
If ignition system is the intermittent problem, could be failing coil or coils, ignition module, crank position sensor, even the computer, or a wiring problem like a bad connection. Testing of each component will be required, or you could start throwing new parts at it, like many people do, until you find the bad part. Find a reputable mechanic-there still are a few, lol.

Car will crank there is no spark have replaced coil and condenser


Test the ignition system output, ignition systems can vary in configuration but operate on the same principal. Ignition systems can consist of a coil, pick up coil, crank angle sensor, cam angle sensor, spark plugs, spark plug wires, distributor cap, ignition rotor and a distributor and any variations of these components. An ignition coil is a voltage stepper coil that transforms a low voltage (12 volts) signal into tens of thousands of volts needed to jump the gap of the spark plug.

This coil is activated by an ignition module triggered by using the camshaft/crankshaft angle sensor; timing is adjusted by the PCM (computer).This primary electrical signal is generated by the PCM which calculates spark timing by using a variety of sensors including coolant temperature, mass air flow, and oxygen sensors. Go to 2carpros.com for a video on how to check this using a 12v light tool. On the engine repair section search, type, "engine cranks but will not start." If my answer helpe you, please leve good feedback. thanks

SKIPPING PROBLEM . SPARK PLUGS & WIRES HAS BEEN DONE. THERE'S NO 12 VOLTS AT THE COIL CONNECTOR PLUG WITH THE KEY ON. LYMAN


Sound like a ground problem; the fastest way to identify the Power and Ground Circuits is using a wiring diagram. If you don't have one you'll have to find out by trial and error as you probe each circuit.

The power circuit is tested with the Key On and Engine Off. Place one end of your multimeter or Test Light on the Battery Negative Terminal and with the other end, probe the Power Circuit. Turn the Key to the Run position. If the Power Circuit is OK, the Multimeter will show 12 Volts or the Test Light will light up. Here are the possible results:
* You got 12 Volts on the Power Circuit
Good, this is a good sign. The next step is to check the Ground Circuit of the Coil on Plug connector that you're testing.

* No Power in only one Ignition Coil
Without 12 Volts, the Coil-on-Plug Ignition Coil will not work, thus you have just eliminated that specific Ignition Coil as the source of the fault. Replacing the Ignition Coil with a new one will only be a waste of time and money since, without Power the new one will not Spark.
Since the Power Circuit is shared by all of the coils on the majority of Coil-on-Plug Ignition Systems. The most likely cause will be an open short in that Ignition Coil's Power Circuit.
You'll have to consult your Repair Manual's wiring diagrams to make sure how everything is wired up.
After repairing the short, re-do the Spark Test to verify the Ignition Coil is now working.

* No Power at any Ignition Coils
The fuse or relay that supplies this voltage is blown or BAD.
You'll have to consult your Repair Manual's wiring diagrams to see where this fuse and/or relay is located and replace as necessary.
After replacing the blown fuse or the defective relay. Retest the Ignition Coil.

Them, the Ground Circuit is tested with the Key On or Off. It doesn't matter because this is a Chassis Ground. Place one end of your multimeter or Test Light on the Battery Positive Terminal and with the other end, probe the Ground Circuit. If the Ground Circuit is OK, the Multimeter will show 12 Volts or the Test Light will light up.

* You got Ground
Good, now the next step is to verify that the Coil-on-Plug Ignition Coil is receiving the Triggering Signal. This info belongs to the next section of this article.

* No Ground in only one Ignition Coil
Without this Ground, the Coil-on-Plug Ignition Coil will not work, thus you have just eliminated that specific Ignition Coil as the source of the fault. Replacing the Ignition Coil with a new one will only be a waste of time and money since, without Ground the new one will not Spark.
Since the Ground Circuit is shared by all of the coils on the majority of Coil-on-Plug Ignition Systems. The most likely cause will be an open short in that Ignition Coil's Ground Circuit.
You'll have to consult your Repair Manual's wiring diagrams to make sure how everything is wired up.
After repairing the short, re-do the Spark Test to verify the Ignition Coil is now working.

* No Ground at any Ignition Coils
This usually happens thru' human error in most cases and is a very rare thing. Usually the engine was replaced and this ground was not re-attached.
You can Ground this circuit with a jumper wire. Jumpering to Ground just one Coil-on-Plug Ignition Coil should provide Ground to all of them (consult your Repair Manual's Wiring Diagrams to be sure).
With this jumper wire to Ground attached, crank the vehicle.
If in fact the Ground Circuit does have an open short, this (the jumper wire to Ground) should make the vehicle start, or at least get the Ignition Coil to Spark.
Repair the open short and retest for Spark or retry starting the vehicle.


Hope this helps. Keep us updated.

The ignition coil on my 89 s 10 blazer smoked minutes after the engine died i replaced the coil now im getting no spark


Inside the distributor car, there is a device called the condenser coil. If your spark coil has shorted out, it may have sent a powerful surge through your entire system causing several items to burn out. The condenser coil looks like a small silver tube with one wire coming from it. It screws underneath the rotor button. Replace that and see what happens.

Okay i just replaced the distibuter cap in my maxima. i have now got spark from the coil but no spark otherwise. i have tested it and thats how i know im only getting spark from the coil


If your getting spark from the coil and none to the plugs.Then its either the wires or plugs. I'm curious .... what are you using to test for spark at the coil?

I have a 99 grand am SE 2.4 4 cylinder and my problem #2 misfire, repalced spark plugs with AC delco rapid fires, replaced coil packs, replaced coil pack housing, changed spark plug boots, had ignition...


A misfire doesn't always have to be ignition... it's just the most common cause. Faulty or plugged injector, low compression. You need to check fuel pressure and test the fuel injector flow. Then check compression. If you don't have tools for these tests, take it to someone who does. Testing is much cheaper than throwing parts at the problem.
