SOURCE: 1995 cadillac deville "won't start"

When you disconnect a spark plug wire, do you get spark when you crank the engine over?
If so,
When you turn the key to the "run" position (do not crank) do you here the fuel pump run for 2 - 3 seconds?
Let me know.
Regards,

I was hooking a new stereo up in my 1991 Cadillac sedan deville and sparked a wire and now its running rough. what could it have did?


What you did was sent 12Volt Power through the Entire car. There is no way for ANYONE to know what damage you have caused. The Computer could be fried, Sensors, the list goes on and on as you can tell about putting the Old Stereo in and it working..

This is the same as Jumping your car and putting the wires on backwards... Only Worse, you bypassed the Security Features of the Fuses....

Sorry but you are going to have to troubleshoot every system to find out what damage has been done

Do you see a light that says SECURITY on the dash somewhere? This can turn off your starter and disable your car. Read about it on this link with options on how to fix it yourself.

I have a 1991 cadillac deville when i turn the key lights and every thing works but car wont turn over


You need to check and see if you have power to the starter,the purple wire while someone is turning the key to run.Should have at least 9 volts to the solenoid.Sometimes if you tap the starter with a hammer while turning key to run and it turns over it is the starter.
