Not sure where you are getting voltage, but the coils get power from the key and a ground signal from the computer. The voltage may actually come from a relay.
So you should have voltage on one side with the key on, and a ground pulse on the other when the engine is cranked. The coils fire when the ground is removed.

SOURCE: 2001 mazda protege will not start

well, with all that you have changed the only two possible things that are left PCM and the ECM....

Do you have an alarm system on this vehicle? If you purchased this car second hand it may have something that is inhibiting the engine from firing. From what you have told us here that would be where I would start looking.

I really hope this is helpfull

SOURCE: Check engine light on

There are three kinds of gasoline engine misfire scenarios, first there is the "under load" misfire and there is the "at engine idle" misfire, and finally there is misfire continuously. All engine misfires exist because one of three things has occurred. First, a cylinder has lost compression, a cylinder needs a certain amount of compression to operate correctly. Second, the ignition system has failed or is failing intermittently, spark is needed at the time of compression to ignite the fuel air mixture. Third, the fuel air mixture is incorrect, proper mixture is needed for the ignition system to ignite fuel properly. If any of these conditions occur in the engine, the engine will misfire.
1. Low or no compression can be caused by

a. burned or leaking intake or exhaust valves
b. worn or broken piston or piston rings
c. worn out camshaft
d. wrong weight motor oil was installed holding the cam followers from adjusting
e. broken valve spring
f. failed head gasket.
2. Ignition system has failed or is failing
a. spark plug has fouled or is worn out
b. ignition coil
has failed
c. spark plug wires have shorted
e. engine control module coil driver has failed
3. Fuel/Air Mixture is incorrect
a. vacuum leak at the intake manifold
b. fuel injector has failed
c. EGR valve is stuck open
d. mass air flow sensor has failed
e. oxygen sensor has failed
f. air intake boot is cracked

common problems:
1. fuel injector has failed or is failing
2. spark plug wire has shorted
3. spark plug is worn out or is cracked
4. ignition coil has failed is failing

Testing a coil on the car is pretty easy. No special tools are required. Just remember to be careful, the amount of electricity generated by your ignition system can be dangerous. If your coil is already off the car, or if you would like a more specific data-driven test, you can bench test your coil. To set up the test, remove one spark plug wire from its plug, then remove the spark plug using a spark plug socket. Next put the spark plug back into the spark plug wire. Be careful not to let anything drop into the empty spark plug hole -- very bad.

ignition mod. grounds,pcm or timing belt could all be it but, I would have to look at timing first.

Next change swap the injector with another and see of the problem moves.  If it does it's a bad injector.

Son has a mazda protege dx runs rough when cold, backfires through intake, gasoline in oil, thinking idle air, but could it be injectors?

Gas in the oil can only get there threw the injector/s. One is stuck open. replace them all if it is worth the car. Back firing, I would check compression on the cylinders first, add a little oil first to all cylinders first, one or more cylinders are dry from the fuel, before putting any more money into it. Back firing threw the throttle body, could be timing or burnt valves.

2000 mazda protege 1.6L my spark plugs are getting soaked with gas

bad fuel injectors. bad spark plugs - inspect and or replace -- bad spark plug wires - test ohms resistance of the spark plug wires with a multi meter (5 bucks at harbor freight) -- or simply replace the spark plug wires.
How was it you tested the coil and spark at the plugs?

I'd lean more towads faulty fuel injection, if you go to repai this, please be sure to add a quality fuel tank cleaner like lucas (the larger the bottle the less the cost per ounce - and works VERY well), You may also want to be sure to replace the fuel filter...
Best regards

1998 Mazda Protege: 1.8l. Getting code cyl #3 misfire. New wires, new distributor and new plugs. Ideas?

Indeed, it could be a bad injector causing the "dead" cylinder. Have someone remove the actuator wires connected to the injectors and do an ohm-meter test on them to see is that #3 injector the only one showing a different value from the rest. If so, you need change the injector. The injector itself is cheap enough, just getting it changed can cost a little. I don't know what that price would be. Now, IF all injectors read out the same or close in values, Then it's apparent you need to have a compression check done on all cylinders. If you find #3 cylinder compression is very low, then you need have a valve job done on that head. Most likely the exhaust valve is burnt/faulty. I'm not looking to scare you, I'm just telling you what needs done and how simple or complex this "miss" can possibly be caused by.

Replacing sparkplugs and wires on 2000 Mazda Protege 1.6 lt engine On top of cylinder 2 and ? are electrical components that attach to plugs. What are they? trying to find diagram and assistance for...

They are the ignition coils, the spark plugs are under them. When you have them off before pulling the spark plugs make sure the holes the plugs are in do not have oil in them, if so you will need new coil boots, plugwires and a valve cover gasket as well.

How do i plug in the spark plug coils? what order?

If it's the four cyl., the first coil pack bolts over the #2 spark plug. The #2 coil pack wire plugs into #3 spark plug. The number two coil pack bolts directly over the number four spark plug, and the #2 coil pack wire plugs into the #4 plug. The firing order is 1-4-2-3.

Where are the spark plugs located on a 1989 mazda mpv

Here's where I found mine on my 2000 protege.

First you're not looking for the right wire type! If you're looking for a standard 1/4" black wire that would normally run from a distributor cap to the plug you would be wrong... so:

Look right on top of the aluminum engine block and you will see the word Mazda and behind that you'll see your engine size. Between the two you'll see a round black rubber grommet and two black blocks with wires running through them (these are the ignition coils). If you look closely you'll see another rubber grommet under all the wiring. Your plugs are under all that wiring in about 4" deep wells.

First you will need to remove four bolts that hold the coils into place (2) per for a total of (4) bolts. If I recall correctly you will need a 10mm socket to get these out.

Before continuing mark each of the four cables with a number (1-4, left to right) so you don't get these mixed up.

Next pull on the rubber grommet labeled #1 (NOT THE WIRE) and pull it all the way out. You will see your plug waaaay down below.

Hints: Using a 6" extension on your socket remove all the old plugs first. When doing so use the rubber sleeve that is inside the socket to help get the plug out of the well.

When putting the new plugs in remove the rubber sleeve from inside the socket so that the socket can be pulled off the plug and out of the well.

1.) Always use an anti-seize compound on the threads of the new spark plugs. This can be purchased along with the plugs.
2.) NEVER over-tighten. Snug is 'snuff.
Hope that helps.
