Have had another thread on this but starting another in a dif direction .. Ive been trying to find a short to ground for few weeks now and cant for the life of me .. Codes were maf low input.. Purge .. Clutch pedal.. O2bank1sensor1high voltage .. Found blown emission fuse .. Replaced.. No change.. Removed fuse box .. Checked connections .. Replaced.. Car wont start immobilizer coming on .. The immobilizer would come on occasionally prior to this but usually i could play around with the fuse box n fix it .. Now mothing.. Ive tried the relearn procedure and nothing .. My question its

Does anyone know what is controlling those sensors ? Coulf i have a shorted out ecu? How can i check that .. Bad fuse box? Again how can i check that.. There doesnt seem to be any worn wires to short things out soo im trying to find an alternative to where this short is ..
