Re: 94 z28 lt1 shuts off
Just to emphasize the importance of reading the codes FIRST, this is what the code description for DTC 46 indicates:
CKT 229 ia a dark blue wire from the theft deterrent module to the PCM pin A25, and supplies the 50Hz signal the PCM is looking for in order to enable the fuel system.
DTC 46 does NOT turn on the SES light.
DTC 46 will set and the engine will stall if the proper signal is not being received on CKT 229 by the PCM after 1.7 seconds.

Re: 94 z28 lt1 shuts off
when I scanned it, it was set on the year 1991 and that's the code I got with it DTC 47, when I realized it was on the wrong year I changed it to the year of my car 94, the reader keeps saying to check cable and now will not connect, just at work will check make and model of the reader after work
cheers

Re: 94 z28 lt1 shuts off
DTC 47 indicates the knock sensor module is missing, or circuit is bad. But if you had the scanner set to the wrong year/engine, it may not be valid.

Innova 3120??? Now where have I heard that before... Oh yes, I wrote a scathing review on it. It won't work on your car despite what anyone says.

I found a work-around to reading the correct trouble codes but it's a bit tedious. See the above topic, posts 6 and 7.
