If you are referring to a firing order diagram so that you can properly arrange your spark plug wires (ignition wires) then one of these diagrams should help out.

If this is not what you are looking for then you will need to be more specific as to exactly what wires that you are seeking information for.

I have nisssan frontier o6 4 cylinder, I put a fuel pump , crank sensor, spark plug, still no start, engine spin over.


I would first check fuses. Second, check for any codes in the system. To make a motor run you need air, fuel, and spark. Pull a spark plug and use a spark plug tester while cranking the motor to determine if you have spark. If no spark, and you have replaced crank sensor I would suspect ignition control module unless you have coil over plugs. Also, when you turn the key on, listen for the injectors squirting fuel. Hard to diagnose with such little info. Just know your are missing one or more elements causing it not to start. If there is a mechanical issue inside the motor this could also cause a no start condition.

My 86 chevy blazer with 305 i pulled out the number 1 spark plug while still in the distributer whire and did not get any spark to the plug when my wife turned the engine over any suggestions


First do the SIMPLE thing: check if the distributor is getting the low voltage supply! If it isn't, that's the whole problem. Next, see if the high voltage coil is getting its low voltage supply and then if it outputs the high voltage...be systematic and save yourself money!

1995 grand marquis cylinder 4 says misfiring changed plugs whires and coilbox lifters and rockers any ideals


Then if the wire did not spark or knock you down it must not be getting spark. You could have a bad coilpak. If it sparks, then look at fuel side, like a bad fuel injector on #4.

There is a test system called Noid lights which plug into the wire harness on the injector. This will show if juice is going in, but a Voltmeter can also be used to verify power to the injector. The loaner programs at big autoparts chains may have Noid lights to lend.

Now if you know the power is reaching the fuel injector, you probably have a bad injector. Disconnect the wire harness to the injector and use an Ohmmeter to test the coil inside the injector. If it is bad it will not show Ohms.

1986 ford 351M turnsover but wont fire up and it gets lots of fuel would it be the spark plugs.


Three things are neede to make a motor run, air, fuel and spark. If your air cleaner is clean and you have fuel in the cylinders then you need to check for spark. take a spark plug out of the head and keep it connected to the wire. Ground the bottom of the plug on the engine (do not hang on to the plug) and turn the motor over. This will let you know if you have spark if you see or hear the charge. Check the firing order as well.

Car wont start


Check to see if your getting spark. Pull one plug whire at a time. with plug in wire. resting on engine (not holding) have someone turn the car over look for spark.

If you have spark in all cylinders. Also check to see if your getting gas.

Check ignition switch as these have been issue for me in the past. Use multimeter and test switch
