Ms3pro no spark

Post by Thelittlefatguy »

Hi!
I have a weird problem with spark on my Ms3pro I'm running Vw pencil coils, and wired them according to the manual. I have 12v at the connector and all 8 ground is soldered together to a larger wire, which is bolted on the valve cover. And if i activate the coil in test mode in tunerstudio, i can hear a slight clicking in the coil, but still no spark.

I have even tried using a jumper cable directly from battery ground to the wire, with the same result.

Any ideas?

Map hose isn't connected on the sensor

1:Connect and correctly calibrate you MAP sensor.
2: Battery voltage is low/marginal
3: Which VAG coils do you have? Early ones require an external ignitor.

Coils are 115 rev b
I also noticed the battery voltage was low. Only a minor thing. The nut to the starter was not tight. But that shouldn't stop it from spark in test mode? In my mind at least.
