Hello All,
I am attempting to troubleshoot a 97 GTI that I currently have no spark and would like to try and get some opinions on the direction I should continue on.
Here is the breakdown.
New battery
New after market MPEM
All electrical connections cleaned with contact cleaner and tested for continuity throughout the wiring harness.
Through testing when the DESS key is plugged in I get two beeps. Start/Stop button works and engine cranks over, but no spark. When checking the white wire to the ignition coil I see .2 Vdc at best. Following the service manual I have tested the Stator and have 58.9 ohms on the generating coil. I also read 46.6 VAC on the generating coil when cranking. For the battery charging coil I have 1.0 ohm (out of spec per manual) and 6.5 VAC when cranking. Additionally, I have tested the primary side of the Ignition coil and have .4 ohm. I have not tested the secondary since it doesn't seem I am receiving the proper voltage to the primary.
So a couple of questions with this-
1. Low oil light active - would the MPEM disable the ignition system due to the oil system ?
2. Would the MPEM disable the ignition system if the engine temperature sensor is bad ?
3. The stator battery charging coil ohm reading is out of spec. Would this cause issues to the MPEM not allowing spark ?
Thank you!
