we are having the exact same problem, exact same year model Cadillac we are looking into 2 answrs that seem to occur when searching net for help : oxygen sensor, and this:

have seen problems where the key does not talk to the computer security system correctly. There is a transmitter on your key that has to talk to the antenna in your ignition switch. It can be very, very intermittent. Usually the fix is a new switch with a new antenna which will comes with a new key that has to be programmed into the computers on your vehicle. This can be diagnosed with a scanner. you can bring up the key input going in to the PCM. If the key input is not valid, the fuel injectors will not fire and so no fuel goes into the engine. or

Had that problem last summer.
Was worse on hot days and sometimes couldn't get it to start after the car was warm.
New fuel pump saved the day! ...

Why does your battery drain on your 1976 Cadillac Seville?

Either the battery has a dead cell and needs replacing or something is pulling power from the battery when the engine is off. I had a problem with my 1986 Cadillac DeVille where the power antenna was stuck and the motor would run all night trying to lower the antenna. To resolve the problem I just removed the fuse for the power antenna motor.


The barber of Seville shaves all of the men living in Seville no man living in Seville is allowed by law to shave himself the barber of Seville lives in Seville who shaves the barber of Seville?

This is the Barber Paradox, where all men must either shave themselves or be shaved by the barber. The barber is said to "only shave men who do not shave themselves" which creates the paradox: as the barber he cannot shave himself because then he would be "shaving someone who shaves himself." The solution, of course, is to have a female barber in Seville.
