Ignition wiring problem

[Elesjuan]

Hopefully this is the right place to post it and hopefully someone can offer some assistance.

I've undertaken a project which I almost wish I hadn't because of the lack of success, wasted money and wasted time here.

Basically I've got a set of the 2001 Toyota Corolla ignition coils which I've attempted to retrofit onto a vehicle which obviously they were never intended to be installed on. This is a project that more than a dozen people have accomplished on the exact same model car with perfect results, but I'm not having those same results.

I have coil part number 90080-19015 which according to the salvage yard was removed from a 2001 Corolla 1zzfe engine. Fellow modders have given me wiring information that they've used with great success on their cars, I followed them to the T and mine doesn't work. At first the car started and ran very very badly, now I'm getting zero spark out of any coils.

The EMS is an adjustable unit so I can control spark settings, dwell control and the whole nine yards. One of our members mapped out the electronics of a coil and found the optimal dwell settings which I'm using, so that should be correct. They fire on a falling edge of the trigger, and I'm configured for that. The exact settings I'm attempting worked fine with the stock coils but will not function with these. All my voltages have checked out, the EMS IS infact sending a signal to fire for the coils, but I'm getting NOTHING.

Here is the question about wiring I have:

Two separate toyota diagrams (one sourced from this site even) show the following..

According to Toyota this is how the pinout should be:

1: +12 volts

2: Trigger

3: Tach Ref

4: GND

According to one of our club members (and supposedly all the people who run this mod) they're using the folliwng wiring:

1: GND

2: Trigger

3: Tach Ref

4: +12 Volts

Doesn't make sense to me that they're working for other people, just not me... and Toyota claims that we've ALL got them wired up in reverse?? I'm highly frustrated here and fear that I've fried my coils somehow? Testing Between Pins 1 and 4 with a ohm meter gives me 27k ohms with all four coils. Testing that using just the coils, AND the harness that I built with the coils plugged in one at a time for testing. Tried to test between all four pins on the connector and the output of the coil for the plug and get NO value reading at all. Thought once that you could test the secondary output circuit by testing between +12volt input and the output of the coil to make sure its good. No reading usually means the coil is bad, but I don't know if thats the case with these?? Is it possible I just got a bad set of coils to begin with? I did buy them off ebay...

Hopefully someone can assist me with my problems here, I've triple checked all the wiring from the harness I built and the cars factory wiring and its all perfect dead spot on. Hard to mess up 4 wires...

Thanks for anything you all can give me!
