2003 Impala no longer comes up with codes,
Is your CEL still on?
My Actron will say 'no codes stored' or 'end of codes'
CEL?? I'll have to ask my son
Check Engine Light. Yellow icon resembles a motor
it was, but not now, still will not start.
Does it come on when you turn key on, even when not running..it should...that shows it works. Codes or no codes. Otherwise bulb may be out. Or OBDII system fuse.
