Help! 1990 Corvette starts then dies

[jtpgencon]

Code 13 on module 4 (ECM) is for an O2 sensor fault. Check the wires for burns or melting, otherwise, pull the sensor and replace.

From the FSM for CCM code 13...
Check for poor connections at the CCM and the DIC which could cause an open or intermittent fault.
It's a pain, but pull the DIC and check the connections.

Thanks for the info, I just received my FSM today and I am going through the codes. I did buy a used DIC because there are buttons missing I will check connections will replacing.
Thanks for the help

I have the Infl rest light on in my 90 Convertible also. I have cleaned all the grounds under the hood on the frame, about four of them . I still have the light. Un hooked the battery for a period of time while doing this and other things also. This seems to be common with 90 models.Don't really know what else to do.
