I put a new computer in my 1884 sunbird, 4 cylinder, the lights will go on but it wont turn over, it won't even try. Any ideas. I am a single mother on low income and can't afford much. Thank you annette

Well, I'd first need to know if the engine turned over before you replaced the computer (tried but didn't start)?

Because your starter or ignition switch could be bad.

Also, how did you know there was anything wrong with the first computer? And where did you get this new computer, and are you sure it works?

Even if the computer was bad, your engine should still turn over, even if it doesn't start.

So I'd check the battery, fuses, starter, ignition switch and all the wires/circuits in between.

It didn't turn over before the computer was installed. The garage told me the computer was gone. I got it from a warehouse in truro. The battery is fully charged. Will I get the starter and all the other things checked? Any other suggestions? Thank You Annette

If the engine will not rotate, the computer would be the LAST thing to check.

Take it back to these guys and have them fix it on their dime.
