Spartan 3 lite v2

hello so i purchased a spartan 3 v2 and the solid air fuel ratio gauge, everything seamed to be working good and recently the reading is just stuck at 10.60 afr even after the car has been running for a while, the power wire is connected to the fuel pump wire relay on an ms3pr ultimate so when the car turns on the wide band has power any help would be great thanks.

Hi,

Please do the tests outlined in the trouble shooting guide and post your results, Spartan 3 Lite Troubleshooting Guide

ok So did the test per instruction and out of the green wire I’m getting 0-volts I checked red power I checked white chassis ground and even switched out black sensor ground from ecu with a spare ground wire everything checked out except no voltage.

If you are using the fuse holder, please check to see if the fuse is blown.

Fuse checked out as well not blown, i even connected directly to battery red power wire to positive and white and black wire to ground and no voltage at all out green wire.
