I have a 94 Z28 and my CEL came on this morning. I've been searching since I've been at work but it's early and I'm not a good searcher any how. I did come up with you're not able to jump the leads on the 94's but most OBD I code readers don't work either? Anyone have an easy way to get the codes so I can get the issue addressed? Thanks!

 

For most 94 models, except for some built during the end of the year, all you need is an OBDI scanner with an OBDI cable. (Plain code readers won't work). If it is a late 94, then you need and OBDI scanner with an OBDII cable or a home made adapter.
