Just tried to start my 1991 cruiser but it wouldn’t start. Also the check engine light wasn’t on with the key in the on position. I checked the ecu fuses in the dash by your left knee they were good so I checked the relay under the hood and it appeared to be good. Also checked the fusible link...
I’ve owned this 80 for 2 years now. It is my daily driver I put approximately 80 miles a day back forth to work. When I bought it had just over 250,000 miles on it now it has 281,000 on it and still going strong.
