Question about Cars & Trucks
See the commentary and diagram attached.God bless you
When you turn the ignition ON before starting the car, the "Check engine" light is supposed to come on indicating that the engine computer (also could be called ECM, PCM, or ECU) is powered on. If the "Check engine" light does not come with the ignition ON, it's possible that there is no power coming to the engine computer (e.g., due to a broken wire, faulty main relay, burnt fuse, etc.) or that there is a problem with the engine computer itself.
Run the scanner/computer for easy diagnostic and fix it.

There is a flat spot at the front of the right side (passenger side) cylinder head will have the last 6 of the Vin and letter code at the end of it for id purposes. You will see it looking down from the top of the motor.

The service engine soon light indicates you have a problem with the engine management system.The only way to get it to stay off is to lacate and repair whatever is not working correctly. Requires very specialized equipment. Take it to your mechanic.

The starter on the Northstar engine is nestled in intake valley underneath the intake manifold. You must first disconnect the negative battery terminal and then relieve the fuel pressure. After you will have to remove the intake assembly to get at the starter which then after that its pretty basic to remove the starter.
Just be sure to torque the bolts on the intake back to spec when reassembling (torque specs are written on the intake manifold in bold yellow lettering from what I can recall).
With these complicated cars you are better off joining a site like caddyinfo.com and reading their how-to forums and asking other Cadillac owners for advice. It`s very easy when you know what you`re confident and have some simple mechanical ``know-how``.
