1G No spark 1g Talon TSI AWD Auto

[custard459]

Hey everyone,

I have an issue with getting spark to my 1g Talon TSI AWD auto. Are there any common issues that prevent getting spark? Any ideas on where I should start? Fuses? Crankshaft position sensor?

I know that this one doesn’t have a distributor.
Any ideas would be helpful I’m not very good with the electrical.

@92AWDHX40 I didn’t see one when we tried starting it. Any ideas on what to look for with the ECU? Or how to check it (sorry really new to all this)

How To Diagnose A No-Start

Diagnosing a No-StartI've been seeing a lot of No-Start related threads popping up lately, and I figured a basic Tech Article for diagnosing a few of the most common No-Start problems might be in order. Any images posted are courtesy of my 1990 GSX your setup may differ slightly; refer to...

Pull it out open looks for any damage burned capacitors

Thanks! And if it looks all good is there any way to check if it is still kicking?

No you showed damage of its not coming pm the dash. Do that first.

Hey everyone,

I am working on a 1g Talon and I’m not getting any spark. Everyone suggested I check the ECU, and that is working perfectly fine. And it’s all 4 of the spark plug wires are not getting any spark, Any ideas?

I heard that the crank angle sensor could be an issue or the coil/transistor, how would I go about checking that?
Is it also worth checking the grounds in the engine bay or is that a waste of time?

What did you verify?
FYI 1g does not have a crank sensor.
Only a cam sensor which functions for both. Did you check the ignition transistor and connector yet?
Sitting 20 years ecu would be my highest suspect.

When checking the ECU I used the old analog multi meter to check the diagnostic readings and it came out with the reading that there are no issues. I haven’t had a chance yet to check the transistor/connector yet. And my bad yes the cam angle sensor
