The car is not reading the key and thinks someone is trying to steal it. Try another key or see a dealer.

SOURCE: 88 cadillac deville, ac blower fan wont shut off,

Most common cause of this is the blower fan (proper name for the fan you refer to) continuing to run is a shorted out Electronic Climate Control Module. This solid state device replaces the older style fan speed resistor block (at about 4 times the price) This unit is found on the top of the HVAC box under the hood. (HVAC means heating, ventilation and air conditioning) The HVAC box is found on the passenger side of the firewall. Look behind the A/C's accumulator. It will have an electrical wiring plug on top of it. It will be fastened to the HVAC box with a few 7mm hex head screws. Very easy to change.
FYI, do yourself a favor and replace the blower fan motor at the same time. The Electronic Climate Control Module usually fails because the motor is drawing to many amps of current. This is because it's bushings are worn out or the brushes are worn out.
This is very common on Cadillacs and Buicks.
PS Not sure why car won't start. Either you drained the battery or blew a fuse which controls starting the engine. Need more info regarding the "no start" condition.

Wont start have changed the crank and cam shaft senior still just turns over

Did you change the sensors yourself? If you did you need to reset the computer. Disconnect the both cables from the battery. Hold them together for 3 minutes. This will discharge the memory in the engine control module. Reconnect the battery and start the car. Let it run for a few minutes then drive the car so the computer will "learn" the new sensors. If the engine still won't start then there is another problem such as fuel pump or not enough fuel pressure to the injectors.

I disconnected the battery cables waited a short time and touched tha cables togeather to reset the ESA . Now when I reconnect the battery cables back on the vehicle it will not start. All the light

Car not starting or turning over indicates towards multiple possibilities. It can be issue with battery or weak battery. But if battery checks out ok, then it can be starter issue or faulty alternator or problem with low fuel pressure or no spark at spark plugs due to dirty spark plugs or faulty ignition coil or injectors getting cracked or dirty and needs to be cleaned.

To confirm the problem, the basic troubleshooting is required.

From start to end troubleshooting these problems I suggest you to check the help link below and follow its procedure: -----

Gas is leaking from my fuel rail (phlegm) on my number 5 fuel injector on my 1994 camaro

  • Park the Camaro on a flat, level surface and set the parking brake. Open the hood and secure it in place with the hood prop. Disconnect the negative battery cable.
  • Open the gas tank to relieve pressure on the fuel lines.
  • Remove the sight shield from the fuel injector with a socket wrench. Loosen the screws on the hose clamps and disconnect the fuel lines connected to the injectors. Keep a rag handy to catch any fuel that leaks.
  • Disconnect the vacuum hose and ignition coil wire, then unplug the electrical connectors. Remove the fuel injector mounting bolts, undo the retaining clips and remove the fuel injectors.
  • Put a thin coat of engine oil on the new fuel injector's O-ring. Place the O-ring in position, install the new fuel injectors and secure the retaining clips. Install the mounting bolts with a torque wrench set at seven pounds.
  • Plug the electrical connectors back into the fuel injectors. Reconnect the vacuum hose and ignition coil wire. Connect the fuel lines and tighten the hose clamps with a screwdriver to secure them in place. Bolt the sight shield in place with a socket wrench.
  • Place the gas cap back on. Reconnect the negative battery cable

    I tried to start my engine this morning and it did start then died i did this four times and now it wont even turn over I was able to rev if to 4 rpms and it just died it may be the fuel pump but I would...

    You have run the battery down, not enough power to turn the starter over. First thing is to look at the battery and see if it is 4 years old or older. If so replace the battery. If not then charge the battery back up but you will need to disconnect the wires from battery first to charge it correctly. Clean the battery terminals on battery and the cable end that connect to battery. The fuel problem is with the fuel filter or the pump. Lack of fuel pressure to injectors causing it to die. Will need to replace filter and pump to correct this problem. Hope this will help you.

    1999 Subaru legacy will not start

    Check your terminal connections, if they are loose they will need to be inspected for breaks. If they are broken you will need to replace the connection. Make sure they are clean and free of corrosion.

    Other possible Problems
    If the car wont turn over your starter could be bad.
    If it turns over but wont start it could be any number of these problems.
    Coil Pack
    Plug Wires
    Spark Plugs
    EBX (Engine Brain Box)
    CBX (Chassis Brain Box)
    Crank Sensor
    Fuel Pump
    Fuel Rail
    Fuel Injector
