Probably not, If it was that low as to keep the motor from rotating the engine would need to be overhauled.
More than likely its a fuel or electrical issue. after the oil is added to fill line check for fuel and is it old fuel ? Yes ?replace it.
Has the car been sitting? Yes ?Is there rotation of the engine no? Starter or Battery replace it jump it. ( turns but does not start)? Yes
Electrical issue check wires, are all plugged into correct spots.
When it ran last was there noticeable issues ?
This should give you some things to try
If these do not get it running you will need a dianostic evaluation from a good auto mechanic.

You need a new oil pressure sender switch. I have had to replace mine also. Not too expensive (15.00) but tough to get to.

With the VIN number a locksmith may be able to get a key code and make you a new key or you may have to go to the dealer for the key code to take to a locksmith. Hope this helps.

My 1997 cadillac deville, northstar w/85, regular oil changes, burns almost 2 quarts of oil every change. It is not leaking.


If your car is losing oil, and if there is no evidence of oil leaking, there is no question that it is either losing it through piston rings or through the head (head gasket or valve guides).
Best thing to do is use a HEAVIER WEIGHT oil than specified for the vehicle when new, regularly monitor your oil level and be sure it never falls below one quart low, and consider having the engine overhauled when you start noticing a performance deficit or hear mechanical noise (such as rod knock) from the engine.

1991 Cadillac won't start, No click from starter, Relays click on and off on passanger side


Check to see if you r battery is too low. They have security systems that protect the battery from reaching levels that will damage it. This will be the problem if you also see the security light flash on the dash and know there has been nothing to trigger it the battery being low will cause this. WebRepcurrentVotenoRatingnoWeight

Hi! My 1999 Cadillac Deville for about 2 weeks started messaging low refrig-ac-off. Check engine light on!.


When you change your oil is up to you,you set the
months & miles you go. Any car with a reminder
for oil is just a gadget

You were told that your low on a/c refrigerant by the
message

Now the check light related or not has to be addressed,
by checking for codes & diagnosing the effected system

Your a/c system needs repair,not added to, only to leak out
& polute the atmosphere

The car wont start but the power (lights, radio, dash) all works. Also 7% oil ife left..could it be the oil level it to low?


Not likely an oil related problem. More likely battery/charging system problem. Have your battery "load tested" and alternator checked for adequate output.

It should be either no Spark or no Fuel.
Possible causes: Out of gas, no oil pressure, faulty oil pressure switch, Bad fuel-pump, fuel-pump relay, needs tune-up, defective ignition control module, wrong air/fuel ratio, defective IAC valve or EGR valve.
Other causes: Wrong timing, bad compression, or clogged CAT.
