    WHAT SHOULD A COMPUTER COST FOR MY VEHICLE?
    iR SURGES SOMETIMES WHEN STOPPED AND THE ENGINE LIGHT IS ON

      An engine light being on does not mean that your computer needs to be replaced. It means that there are fault codes stored and there is a problem with some sensor data being received (or not received). There is not a way to estimate what your bill will be until someone diagnoses this.

      It depends on if a new computer from dealer, or remanufactured or even a used one. could be as much as $600 or as cheap as $150, this is parts cost and does not include diagnostic labor or installation labor

    My friend changes his thermostat is a 2001 Cadillac Deville, since then it is acting like it has an air block.
    After changing the thermostat, the ngine acts like it has an air block in the cooling system. How do I get the air block out of this model car?

      There is no special bleed procedure for this vehicle. What were the symptoms that it was decided to replace the thermostat? The engine must have been running hot or even overheating before, or you would not have replaced the stat, right? My gut feeling says bad head gaskets of which they are well known for.

      Please clarify something. If you take a line off the fuel filter and turn the key to crank, you are saying that there is NO fuel flow there? Yes / No clear answer please. This "carb" you refer to is not a carburetor, it is a Throttle Body and the system is known as TBI or throttle body injection, just sayin.

      Test AIR PUMP A fuse. The P0420 means the cat is junk about 90% of the time. About 10% of the time the rear O2 sensor is junk.

      Do you have a security light illuminated on the panel? If so you likely have a faulty ignition lock cylinder or a faulty ignition key. the key has a resistor embedded in it that the ignition lock cylinder and security module read the value of and this is like a password that enables fuel.

    Why does my fan for heater & air not work?

      The blower motor runs by receiving battery voltage and a ground. You just stated that there is battery voltage at the blower motor. Now check and confirm that there is a ground. It should run and if it does not then the motor is junk. Try smacking it with something while power is applied to it. It may begin to run.

      Book labor for this job is 12.5 hours, but I doubt anyone will pay any mind to that. Major job that distracts you from getting other work done. Cannot be done properly in 12.5 hours so labor gets upped to about 18 hours at around $100 / hour plus the list price on the parts. Most shops will not do a job like this cheap. But ya never know. Requires high skill level. Often you get what you pay for.

    Truck will run but fuel pump runs down the battery

      Replace the fuel pump relay or at least remove it and that should stop the pump from running.

      Remove the START 1 relay from the underhood fuse box. If the problem is still there then yes the starter is stuck and needs to be replaced.
