Codes ???

[Gottado]

I've got a '94 K3500 and it has developed some problems lately. How do find the codes on the 94? I know it blew a donut on the crossover....can that affect the turbo operation?

If you have an exhaust leak it will affect the turbo
As far as the codes go to www.ssdieselsupply.com and look at FAQ its in there how to read the codes on the 94 It worked for me
