My 97 Cadillac deville won't start could that be that my oxygen censor's are not good???


Even a bad oxygen sensor couldn't keep the car from starting. It has probably lost spark or fuel to the engine. Listen for the fuel pump "whir" for 2 seconds with the key in on position, not start. Or have the fuel pressure checked, and scan for possible trouble codes. That is the place to start: scan, fuel pressure, check for spark.

2001 cadillac deville with sensors in key to start car ,.


Technically you don't. You may be able to have the lock cylinder replaced and a new key cut at the dealer from the VIN number.
The new key has to match the old chip.

Hello! when you say you checked the MAP sensor what do you mean? Did you take voltage readings at idle ? A vacuum leak is the likely culprit, especially to the MAP...The minor shake at idle being the major clue...Send a comment...guru..saailer

Tuned up car changed 02 sensor full tank of fuel still running rough


Oxygen sensor only report the condition of the engine the rough running condition can range from a worn sparkplug wires to worn sparkplugs to valve problems to injector problems. with the cadillac deville a tune up should be the first attempt to smooth the rough idle with the inspection of the cap and rotor cap and rotor do have a tendancy to arc internally and create misfire so does sparkplug wire that can leak spark voltage to ground and create misfire. the spark plug wire especially if they are brittle and hard can create issues

Cranks but wont start


check for spark and fuel
if there is no spark but has fuel then the ignition module may be bad
if there is fuel but no spark then the fuel pump may be bad
if you have both then may be the ignition lock cylinder ( if it has the chip on the key )
