My blazer has had a no starting issue months now. Just cranks an cranks. Initially security light was on an blinking but it has gone back off an all lights are normal except check engine which last scanned the codes was a key ignition malfunction & a security issue. I have tried the key on an off thing for 2 years of my life (not seriously but takes long time lol) have checked fuel pressure it is fine. An fuses checked an so on. So now I'm getting told to buy a remote start an should fix my issue. Anyone point me in right direction as what kind will work ? Its a 2003 chevy blazer. 2 door. Automatic. 4.3. And its 2wd. The locks and windows are all manual. Idk if makes a difference but yeah. Anyone?
