I have the wiring book for $5 plus shipping if interested.

These cars used ignition modules. Probably a 4 or 6 pin connector.

    OK, Is this a Canadian car?

    If U .S. car, it has TFI module on the distributor (US only). The pick-up in the distrbutor provides the signal to the TFI. Thered/lt green wire has battery voltage with key on. Battery voltage is supplied by Red/Lt Blue when key is in start position.
    Black/Orange stripe is ground.
    Dark Blue wire and Yellow/Green dots are signals to the engine control module.

    Usually the TFI fails due to heat.

1999 ford expedition 4.6L cranks but will not start

you might try starting fluid in air horn to see if it tries to run, then at least you would know it is not an ignition problem and only on the fuel side. Maybe wiring connector to crank sensor is bad. Really not sure how you would check if Anti-theft is preventing starting, but keys are only 1/2 of system and PCM is the other.

2008 cobalt accessory wire color for car radio install?

I looked that up as I was puzzled myself, and here is what I found:

Car Radio Accessory Switched 12v+ Wire: The radio harness does not provide a switched power source. Run a wire to the fuse box for switched power.

Or this:
Car Radio Accessory Switched 12v+ Wire: Run a primary wire from the back of your radio to your to the steering column and use the brown wire in the ignition switch harness.

I have a 1999 dodge Durango 4x4 with a 5.9 magnums v8. I've gone through 3 ignition coils in a 2 week span. Could it be just a bad "run" from the manufacturer? Or is there something I'm missing?

Hi Chris
I am not familiar with your particular vehicle. But...
The main reason that an ignition coil would fail is through an open circuit in the primary winding. (Use the ohms section of a multimeter to check for continuity) Now, the only way you can open circuit the primary winding is to burn out the primary winding.
Considering that this connects to 12 volts via the "points" or "contacts". There isn't much to go wrong.
So.... Here's what I think is happening.
From my old auto electrics background.... A coil connects to the vehicles 12 ignition circuit via a special nichrome wire (often inside the wiring harness) This Nichrome wire acts as a Resistor before the 12v current reaches the Coil's Primary winding. This cuts down the current when the the ignition key is in the running mode. When you start the vehicle, the full 12v current bypasses the resistor to give to a BOOST while starting the vehicle. When the key returns to the Running position the coil is being supplied by the resistance wire so the current is reduced.
Note: There would have been 2 wires connected to the Coil originally. One is 12v from ignition switch "run" position and one from ignition switch "start" position.
If you have wired the vehicle different than the original wiring or have used a different wire then you may actually be running the vehicle directly on 12v from the ignition/battery. This would eventually burn out your coil.
If necessary, add a resistor (large wire wound, ceramic), to the circuit. Purchase or make your own.... once you know how many ohms you require to reduce the current.
Hope this solves your problem. Pitty you have paid for 3 coils before finding out.

What color wire do I need to cut just to put a toggle switch on to kill engine on 1990 Chevy Cheyenne 4.3 liter

If you kill primary voltage to the ignition coil, the vehicle shouldn't run. Primary voltage to the coil is the positive side of coil. It's a pink wire comes from ignition switch to ignition coil. There are many ways to do something like this. You can kill spark, you can kill fuel, whatever.

Wont run smooth &misfires has code po 352 ignition coil #2 primary circut

First you should have a Haynes Manual for your specific car that's available at most parts stores. Since it states that your "Ignition Coil B primary or secondary circuit malfunction", then I would first measure the Coils Resistance which is listed in your Haynes Manual. If it comes up incorrectly for the values given, then replace the coil, if not, check the Z2 Circuit which is the Ground to your PCM or computer. It should be a 12 gauge wire, black & tan that's bolted to the Engine block for a corroded condition. This corrosion will throw multiple codes except for the PCM's Ground. In the Haynes Manual there is a wiring diagram of your PCM in the back that, if I'm wrong about the color of the wire, will give you the proper color.

Does anyone know what the code po316 is on the ford escape v6? there is also po300b,po303,po304b,po357and po353 codes

P0316 .... Engine Misfire Detected on Start-up (first 1000 Revolutions)

P0300b .. Random/Multiple Cylinder Misfire Detected

P0304b .. Cylinder 4 Misfire Detected

P0357 .. Ignition Coil G Primary/Secondary Circuit

P0353 .. Ignition Coil C Primary/Secondary Circuit

From codes you need new spark plus, Ignition Wires, and ignition coils

Engine turns no spark

No spark can result from a bad coil or bad ignition module. If there is electrical signals at the primary coil but no spark then there is a problem with a coil. if there is no electrical signal at a primary coil then there is a problem with the ignition module. Here is the image of your coil. The 2 metal screws sticking out for wiring are the terminals of the primary coil. Need to test that to determine the root cause of the problem. Good Luck.8cf6119.jpg

I need to know the timing sequence for a 1998 Mercury Mystique 2 liter

ignition timing or valve timing?

ignition timing not setable.

The ignition system consists of an ignition coil, spark plug wires and spark plugs.
The crankshaft position sensor signal is the basis for ignition timing calculations. The alternating voltage signal from the crankshaft position sensor is digitized by the powertrain control module. This digitized signal is then used to position the closing time of the primary circuit of the ignition coil.
Ignition angle is determined by the powertrain control module in response to engine operating conditions. Once ignition angle has been determined, the powertrain control module interrupts the current to the primary circuit of the ignition coil thus triggering the ignition spark which is supplied to the cylinders through the spark plug wires and spark plugs.
The ignition coils are triggered by the powertrain control module in pairs (cylinders 1 and 4 and cylinders 3 and 2) sending one ignition spark to the firing cylinder and one ignition spark to the corresponding cylinder on the exhaust stroke. This make sures that any unburnt fuel residues remaining in the cylinder on the exhaust stroke are re - ignited to provide cleaner exhaust emissions.

Bypasing ignition

Hotwiring is used inilligal activities but in your case i dont have a problem in showing you how its done.

1.) Remove the part of the dash covering your ignition key assembly
2.) There should be 5 to 8 wires there
3.) Locate 2 wires of similar color
4.) strip these wires and tie then together this will turn on the ignition
5.) find the starter wire usually blue and touch it to these wires, Imidately remove it when the car has started.
6.) tape them up

If your wireing is a bit different or you dont have similar color wires then
use steps 1 and 2 from above
3.) locate the the on positive wire
4.) run a wire grom the negative battery pole to the on positive wire. (U can strip each wire there and ground it to the wire from the battery pole , the correct one will turn the ignition on.
5.) once located tie it to the ground.
6.) touch each one of the expose wires one by one until the car tumbles and starts.
