I bought this car needing a starter. Once I finally got the starter in it wouldn't start. After some digging I found there was no spark so I checked for codes but there wasn't any. I had the battery unplugged when u did the starter would this cause no spark?anything with security systems? I have a reading for rpms so u dont think its the cps getting a little frustrated as electric stuff isn't my thing. Any ideas on what i should try?
