I have a '85 olds cutlass supreme that came with a v6 but now has a 350 v8. Anyhow it has started, ran, and drove fine for a couple months now. Car also has a 'Stellar Alarm System' installed on it to. The problem: is that now car will not start now it won't even turn over. But all the lights, fans, signals, radio, and etc. work. Just replaced ignition key/cylinder and ignition switch. Checked battery connect/disconnect. And wiring the best I could. Please help with sum ideas. Thank u.
