2.5L 200 EFI Motor - No Spark
Hello All,
I've been fighting this issue for a few weeks now and looking for any input or additional areas to test. Here is a list of all the troubleshooting I have done so far.
Stator test complete
- blue wires measured 185Vdc
- red wires measured 35Vdc
- resistance measurements for each were good as well
Trigger test complete
- each wire to ground measured 1.2-1.3Vdc
- black sleeve to yellow sleeve wires measured 3.8-3.9Vdc
- I did switch out the trigger assembly with a new spare I had from my 2.4 motor and the results were the same, so I switched back
VST is powering on and fuel delivery is good
Power to each coil is measuring 120-125Vdc, and it should be 180-200Vdc. I switched out coils from my 2.4 motor and the results were the same. I knew this step was a long shot, but I was frustrated at this point and wanted to do something.
Switchboxes were both replaced a few hours ago.
Black/Yellow wire to switchboxes measures zero with key off, but measure 1.5Vdc with key on and here is where I have a concern. I believe this should read battery voltage with key on.
