Well long story short Im getting no spark. I've tested just about everything at this point.

I've got new spark plugs

3 dizzys to test on that are known good

Tested the grounds

Continuity on igniter wire all the way to igniter

It seems that the only thing I've seen wrong is no power on the actual coil. But seeing as that is a problem on all 3 dizzys what could cause that?

Is this the same continuing issue as in this thread?

In that post you stated that you got the ECU wet.

jake00si

This is a whole new issue..I thought the Ecu had gotten wet but it was just the starter that had gotten wet and shorted out.

test the ignition coil,Is it a b16a2?

It could be your ECU or your main relay. If the coil isnt getting any power thats your problem. Check continuity between the power source and the wire for the coil

jake00si

No it's LS/v now. And I'll swap out the Ecu today but I'm not sure if it would be the main relay since it clicks like normal and I'm getting fuel pressure

What car?

Any CeL codes?

Does the Blk/Yel wire attached to the coil and igniter unit have battery voltage with the key in ON(II)?

Does the Yel/Grn wire running between the igniter unit and ECU have a short or open?

jake00si

It's an Em1. Stock harness. Motor is ls/v. There is continuity between the igniter and the Ecu. Yes the yellow and black has power with key on. No cels

Former User

Check the wire for short.

jake00si

I've swapped the ECU with a buddy and still nothing. Tested the ignition switch and it seems to be good. When I test the dizzy with it plugged in..no + at the coil but i'll get + all around the coil..going in and coming out. But shouldnt the - side of the coil be grounded instead of hot? Makes sense to me

Rather than bump, do this:

canadaek

the coil is grounded by the ignitor to cause spark . check you crank sensor and do what ron said .

tundra2000

did u check the ground on the thermostat housing?

jake00si

i took a few days off from messing with it. tomorrow im back at it

jake00si

Pulled out the whole harness to do some continuity checks, check for shorts and ohm it out. Everything seems fine so far..which leads me to believe it could be the ecu (even tho i've tried two p28s).

Battery is good (brand new)->Ignition switch good->Main relay good (tested it and the fuel pump works)-> Tried 2 different P28s which seem fine -> 3 different dizzys -> Spark Plug wires ohm out fine-> New Spark Plugs.

Grounds seem fine but I might not be getting the pulsing ground from the ecu to create spark.

Other than changing out the ecu again im at a complete loss

its not a relay? i had the same problem and i had to replace a like bmfi relay, or something like that haha

jake00si

who knows..it could be anything. but im under the impression that only the main relay controls it...and that is within tolerance. wth is a bmfi relay?

mark11017

main relay only controls fuel other then supplying power to ecu which if it wasnt turning on obv you wouldn't have spark.

jake00si

Sooo pretty much pull all the relays...sweet. lets hope this is something i've overlooked
