igniter problems

[wilddream]

Hi there

I seem to be having some issues with my ignitor

I have a toyota corolla with a 4agte engine, link g4 storm ecu with link 2 channel ignitor.

Its a brand new engine so ive been having trouble with the timing and geting it started.

I got it firing and turning over then sudenly no spark what so ever ive checked the coils and leads they seem fine.

But when checking the igniter i noticed something with the wiring

I turned off all the aux out puts but there is still two wires with 12volt and one with 5volt going to the igniter.is that corect or have i wired it incorectly?

Also any other i deas as to why id have no spark now? Posibly stuffed igniter?

Many thanks for your time stefan

Hi Stefan

 

You will see 12 Volts on the two wires that head off to the coils.

I would not expect to see one with 5V while the engine is not running.

 

You can also do a ignition test on each ignition drive.

 

Also make sure you have selected the correct ignition configuration being distributor or wasted spark.

Thank you for the reply,

The wire that has constant 5v is the tacho wire just making sure but that wire should be from a aux output and that should be set as tacho on the laptop?

That mayb my problem as i double check everything and even with the keys out of the ignition there is stil power going to that wire.

Sounds like you might have a back feed. There should be no voltages at the ECU once the key is turned off.

You are correct in the tacho out is a AUX output and will go from there to the dash.
