exact part name?

[Winfield1990]

So to fix the no spark issue in the car I just bought , 93 festiva gl I went ahead and bought an ignition coil its on its way through the mail still resistance was ridiculous.

I also went ahead and checked my distributor out earlier today and read the resistance between the black wire and the yellow with green stripe and got crazy resistance amounts also. So thinking the "pickup coil" incase thats what its called in this distributor needs to be replaced.

however I cant find the part , is it under a special name or even available without buying another whole distributor? There are no festivas around here to take parts off of , that ive been able to find.

Is the part your talking about inside the distributor? If it is located inside of it then its the ignition control module. That would cause a no spark issue.

[Winfield1990]

yes its the part inside of the distributor .... when I look up ignition control module shows identical picture to whats next to the ignition coil that says power unit on it... Just wanted to make sure I did not order the wrong thing.

[Winfield1990]

this is whats inside of the distributor.. Almost identical looking anyway minus two magnetic pickups.

but everytime I see whats labeled ignition control module I get something thats similar to whats next to the ignition coil near the fusible link

93s are EFI and the camshaft position indicator/sensor/pickup (whatever that thing is called) is right inside the dizzie. This is not a replaceable unit and requires getting an entire dizzie. With key on and engine turning you will have no spark even though you will have live lo-tension wires on either side of the high voltage line coming out of the coil. The ECU is not receiving a signal from the gizmo inside the dizzie and is therefore not signalling the ignition system to fire.
New and rebuilt dizzies cost an arm and leg. Check the wreckers and u-pulls for early 90s B6 engines etc that have an identical dizzie and grab one of those to try out. Then take your time lining up the key into the camshaft (easy to do wrong) and remember which one of 3 different positions the rotor fits on correctly.
It's nice have lots of spares of things lying about so that you can test parts simply by swapping them out.
Good luck!

the reason you got "crazy resistance" over those 2 wires is because you were testing an inductive pickup. this is normal. it feeds a signal to the ICM (the little box you identified as Power Unit, next to the coil). If the coil failed, it can easily overdrive and wreck the ICM. the ICM can be easily had at any junkyard from a multitude of Mazda powered cars.

Note: the ICM controls the ground side of the coil. it is a solid state switch that is triggered via the inductive pickup in the dizzy. if this part has failed, you will never have spark.

Could you walk me through testing procedures of the ICM and distributor coil?

The search feature should lead you to an excellent post on how to test the distributor of EFI cars. I never paid much attention to that post at the time because I am blessed with numerous spares to try out rather than diagnose each and everything.

[FestYboy]

ICM is easy, take the coil harness plug and probe the ground wire with a test light (its the smaller of the 2 wires and can be verified by NOT having power present with the key on). take the test light and affix the other end to the POSITIVE battery post. now crank the engine..., a good pickup and ICM combo will cause the test light to flash at you. if it doesnt flash, grab the ICM you just picked up from the junk yard and insert it, try again. (its likely the alternate ICM isnt bad...).

Alternately, its also easy to grab a pickup from many Mazda engines of the same generation...

[Winfield1990]

would a volt meter work instead of a test light to test the pickup / icm combo? I do not have a test light

[FestYboy]

no, volt meter isn't fast enough. and you NEVER want to use a sweeping needle style volt meter on a car (well, almost never, but we won't get into that).

[Winfield1990]

alright well I actually stumbled on a test light its intermittent atm , so if can clean up some contacts and make sure can get it working right. When get a chance try testing everything out... atleast my hayes manual got here.

[FestYboy]

its a start

[Winfield1990]

well used test light on the positive battery terminal , and the black/yellow wire to the ignition coil no light flashed while cranking.

I do not recall ever hearing the relays click on ever though , and im not entirely sure my fuel pump is priming , I do not hear anything , granted my back seat is still in and not even sure the pump works to start with. Have not tested fuel pressure , or anything.

So ill have to try to get to the relays to test them a little later if I get a chance , when I get my tools back to the house.

[Winfield1990]

Progress....

After fiddling with some connectors , inspecting the main relay which looks corrosion free , remove and cleaning a few grounds even though they looked clean to start with. I got voltage back to 12 to the coil input , along with tester showing a good icm / pickup combo.

Volt tested the best I could with my voltmeter since it only goes up so high , the output voltage of the ignition coil and spark plug , and wire out of and into the distributor cap everything looks sufficient to produce a spark but I only tested 1 plug output wire and plug so far , I am getting fuel atleast in 1 cylinder that is due to a puddle at the tail pipe , but I dont hear anything remotely close to spark ignition yet.

So I guess I am going to test each spark plug hopefully get a visible spark grounding the plug out , along with compression check then look into timing , maybe each injector individually.
