My ZR-1 is wigging out bad!!!

[ffvetteman]

I started my 92 ZR-1 for the first time in over a month and all hell broke loose.

My check engine light stayed on along with my 'service ASR' light. I could not turn on the power key either. And I drove it around the block and noticed the digital temp sensor was not working, but the guage was. Then about ever 20 seconds, the security light would flash and at the sme time it would flash 'sys' where the digital readout for the temp should be. It would flash 3 times then go back to normal and start all over again about 20 second later.

It also was holding an idle of about 1800-2000RPM. And when I turned the key to start the cooling fan would start right away.

The car is all stock except for the Samco duct and the DRM chip. I put the stock chip it and it made no difference.

The good news is the service ride control light is off now that I tightened the cap nut.

Where do I start??

I did disconnect the battery for a few hours, which made no diference.

Any one got any ideas?
