Re: 89 camero electrical
Check your fuel pump relay. Could also be an accessory power relay, though I am not sure if Chevy used them in 89. I had a pherd with a bad APR. Did very much as you described. Took me a new battery, and alternator, and a lucky day hearing the fuel pump buzz to find it though. Part was about $13.
