Instructions1 Use a wiring diagram for the year model of your vehicle. Locate the terminals running into and out of the ignition module. Placement of the module varies from model to model so check the appropiate service manual of your vehicle for the exact location.
2 Turn the ignition on and use your DVOM to check for voltage to the ignition module and the positive terminal of the ignition coil. Place the negative lead of your DVOM to a solid ground and use the positive lead to probe the wires running to the ignition module and to the ignition coil.
3 If your DVOM shows that voltage is present at both locations, remove the DVOM leads and set the meter aside. Connect the ground lead from the 12-volt test light to the negative terminal on the ignition coil. Have your partner crank the engine over several times. Your test light should flicker on and off. If so, your module is working properly and no further testing is necessary.
4 If your test light does not flicker on and off, visually inspect the wires running into and out of the ignition module. Look for burn marks, melted wire insulation and breaks in the wires. Use your wire splicing tool to remove the bad area in the wire and use your wire connectors and splicing tool to repair the faulty wires.
5 Use your DVOM to check for an open circuit condition in the primary coil winding. Touch the negative probe to the negative terminal on the ignition coil, touch the positive lead to the positive terminal. Set the meter to read ohms. If the reading shows infinite ohms, your ignition module is faulty and should be replaced. Follow the service manual instructions for replacing your ignition coil.
6 Look to see if the DVOM test shows low to no ohms; if so, then you have a faulty ignition module that will have to be replaced. Follow the service manual instructions for your vehicle to replace the module.
Thanks

SOURCE: lack of power, hesitation, #1 miss firing

you may need to perform a leak down test to the cyliner and maybe you may have carbon on that valve. make sure the new spark plug wire has the correct continiuty

SOURCE: It seems like one of the cylinders is not firing.

first need to check if fireing or not , your saying it seems to be? Try removing plug wire with engine running and hols a inch or two away and see if you here the engine idles down , if so it's fireing if not may be coil weak, good luck.

PO300 multiple misfire detected it was saying # 3 Cylinder changed spark plugs and wires,coil pack,# 3 fuel injector, any suggestions


Do a compression check, there is a chance that you are down on compression on #3. Or make sure that your injector is firing on #3. Could have a bad wire going to the injector.

I have a Mitsubishi gallant cylinder number 1 not firing but spark plug is firing engine misfire,engine check comes on for it to start and it has a hard start help.


If you have spark, but no fire, then check injector for proper activation. If good, check compression. If injector good, and compression bad, possible head gasket, valve, piston, etc.

Code 306 means cylinder 6 is not producing power. And as you know it takes fuel, spark, and compression at the right time to make power.
Generally, if the injector is firing at the right time the spark plug should be firing as well.
Are you sure the plug is firing ? And is it possible injector 6 has no fuel to spray ?

I'm assuming you have done a compression test and all cylinders have equal compression, right ?
If you think it is a fuel problem, you would check for power and a ground signal at each injector before replacing them.

Dead cylinder number 2 bad injector number 2


use a digital volt meter,put it on the ohm scale check number 2 fuel injector should be 11 to 16 ohms if not reads zero fuel injector faulty.if numbe 2 fuel injector okay.use noid light hook it to fuel injector electrical connector with fuel injector disconnected and see if pcm is firing the fuel injector noid light should blink when cranking the engine.if light steady pcm not firing 2 fuel injector,if noid light dont light up.there is a open in the wiring connector 2 fuel injector 2. if fuel injector okay,check spark plug, carbon foul you have a bad ignition coil or wire if you see oil on spark plug you have worn piston ring or leaking valve guides allowing oil to foul out spark plug.do a compression test check compression to see condition of the cylinder.

Check engine light is on, they say multiple miss fire in cylcinder 6. but no one can find the problem van runs great


first do a cylinder compression test on engine to verify good engine compression this should be around 110psi to 175 psi check for vacuum leak, intake port for #6 cylindermay be leaking air, or also check coil for that cylinder, if wire and spark plug have already been changed, last replace fuel injector for that cylinder.
