Yes there power to the injectors power to coils noting comes out


Yes there power to the injectors power to coils noting comes out ? Is the PCM - engine computer turning them on and off ? Do you know how to test control drivers inside the engine computer ? Videos on youtube . All you need is a test light , pin out diagram for PCM connectors and a little common sense . You can find wiring diagrams at http://www.bbbind.com/free_tsb.html

Working in a mazda mpv 2001, i cant find the ignition control unit, when i look for the part on ebay they sell the part as: ECU-ECM-PCM, question: is the ignition control unit inside the ECU-ECM-PCM?


It appears from a wiring diagram that there is no ignition control module. The ignition coils' primary circuits are grounded through the PCM. And the wires to the sensors are all from the PCM.

Here is a link if you want to see all your wiring diagrams. I found the above information under System: engine; Subsystem: fuel controls.

No hot wire to the coil 1997 Plymouth Voyager 3.3


Does the check engine light come on whe you turn the key to ON? It should come on, just as a little alert to you that the pcm is powered, and then go off once the engine is running. I'm not certain, but I believe on your car that the coil signal comes direct from the pcm, the engine computer. Check all the fuses in the power distribution center, especially a pcm fuse if you have one there. The Automatic Shut Down relay (ASD relay) is also there in the box. This relay cuts power to the coil and to the injectors when key is turned to off. Maybe something is going on there, you might try a different relay just to check. I think the A/C relay may be the same as the ASD relay, check the numbers on the relays. One shoulde be swappable with the ASD relay.
Good luck, I don't know what else to suggest. It would help you to find a wiring diagram just to check the engine ignition aqnd starting circuit, see how the coil gets its signal. Car repair manuals do have wiring diagrams.

Do you know how to test electrical circuit's with a volt meter ? Power an grounds and control for the coil #3 cylinder ,plus fuel injector ? If you don't know how to do automotive electrical circuit testing ,your best bet would be to take it to a qualified repair shop. The coil is computer controlled , pull it an see if you see or hear it sparking . Is the fuel injector firing. ? Videos on youtube showing how to test. Do you know what a wiring diagram is ? Free one's here http://www.bbbind.com/free_tsb.html Enter vehicle info. year ,make , model and engine . Under system click on engine then under subsystem click on fuel controls . Click the search button then the blue link. Scroll down to diagram # 6 . Coil circuits . Pink with black trace - B+ voltage , black is ground , brown is signal ground in the PCM - computer . orange with white trace is coil trigger signal from the PCM . Diagram #9 is fuel injector electrical circuits . Test power and grounds . You probably have a bad coil or injector ,wiring issue , or a bad driver inside the PCM . If the PCM needs to be replaced it will need programming , dealer only .

I need ignition coil diagram ford focus 2000 LX (connections back 4321)


you have a single 3 or 4 pin connector to the coil pack. Someimes the wires get corroded and break off at the connector. Ford has a pigtail kit to fix that issue. Usually a misfire with the check engine light on.

Green/bluestripe is from ignition switch

Black/green stripe is to PCM (computer)

Black/orange stripe is to PCM

These last 2 wires are what the PCM uses to fire the spark plugs 2 at a time.

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.
