To reset the immobilizer on a 2008 Mazda B50, you will need to have the key fob for the vehicle and be able to access the driver's side door. The process is as follows:
Close all doors and turn the ignition key to the "off" position.
Press the brake pedal and hold it down.
Press and release the "unlock" button on the key fob.
Turn the ignition key to the "on" position and release the brake pedal.
Press and release the "lock" button on the key fob.
At this point, the immobilizer should be reset and the vehicle should be able to start. If the above steps do not work, you may need to refer to your vehicle's owner's manual or contact a Mazda dealership for further assistance.
It is important to note that the above is a general guideline, the actual process may vary depending on the version of your vehicle, it is always recommended to follow the manufacturer's instruction or consult with a professional.
I deleted the new boys answer. He is answering questions that don't make sense for points.
When the engine light comes on and is flashing, it is sensing something that may be an issue, when it is on solid, you do have an issue. Only a pro grade scan tool can read all codes including historical code entries. Of course when you disconnect the battery, you lose them all.
What I would suggest you do is move/swap the coils from Cylinder 1 and put it in Cylinder 2. Also check the wiring connectors on both 1 and 2 and give them a spray of electrical contact cleaner. Then run the car and see if the Misfire Code moves to Cylinder 1. If it does, then it is the coil that is faulty.
Also when you replaced the spark plugs, did you check the spark plug gap with feeler gauges, or were they pre-gapped plugs?
no year told nor any engine told or a VIN
why not tell the job first???
or read the service manual , buy it.
is the cam timing lost , say CAM
my wild wild guess, is cam belt snapped/
keep in mind if the engine (a secret) is the interference type.
the next step you do may wreck valves in the DOHC head.
do not crank it over now or $2000 damage
post your vin first
then tell what failed. name 1 part out of time./
It sounds like there may be an issue with your ignition system. When you hardwired the fuel pump, did you also bypass any other electrical components such as the relay or the fuel pump control module? If so, this could be the cause of the lack of spark from the coil. I recommend double checking all of the electrical connections in the ignition system to make sure they are secure and not damaged. It's also possible that the issue could be with the coil itself or the electronic control module (ECM) that controls the ignition system. If you are unable to find the cause of the problem, it may be best to have a mechanic diagnose the issue for you.
Unfortunately, there is no way to get rid of the anti-theft deterrent in the 2004 RX8. The only way to disable it is by using the vehicle's key fob to deactivate the deterrent. If you are having trouble with it, you should consult the vehicle's manual or contact a Mazda dealer for more assistance.
A malfunctioning oxygen sensor: The oxygen sensor measures the amount of oxygen in the exhaust and sends this information to the engine control module. If the oxygen sensor is faulty, the engine may run too rich or too lean, which can result in excessive fuel consumption.
A clogged air filter: A clogged air filter can restrict airflow to the engine, causing it to work harder and use more fuel.
A faulty fuel pump: If the fuel pump is not working properly, it may not be delivering an adequate supply of fuel to the engine, causing it to consume more fuel in order to compensate.
A leaking fuel injector: A leaking fuel injector can allow fuel to escape from the engine, leading to an increase in fuel consumption.
To determine the cause of the excessive fuel consumption in your Mazda Demio, it is best to have it diagnosed by a mechanic. They will be able to perform tests and inspections to identify the problem and suggest the appropriate repairs.
It sounds like you have a leaking engine cylinder head gasket, the combustion gases are getting into the cooling system and causing an air pocket, this leads to overheating and other symptoms you mentioned.
If your Mazda Demio 2011 starts but does not idle properly, there are a few potential causes and steps you can try to fix the issue:
Check the idle control valve: The idle control valve is responsible for regulating the engine's idle speed. If the valve is faulty or not functioning properly, it can cause the engine to not idle correctly.
Check the air intake system: The air intake system is responsible for bringing air into the engine, and if there is a problem with the system, it can cause the engine to not idle correctly. Check the air filter and the intake hoses for any blockages or damage.
Check the fuel system: The fuel system is responsible for delivering fuel to the engine, and if there is a problem with the system, it can cause the engine to not idle correctly. Check the fuel filter and fuel lines for any blockages or damage.
Check the ignition system: The ignition system is responsible for providing the spark that ignites the fuel in the engine, and if there is a problem with the system, it can cause the engine to not idle correctly. Check the spark plugs, ignition wires, and ignition coil for any issues.
If you are unable to diagnose and fix the problem on your own, it is recommended to have a mechanic or dealership technician take a look at the car. They will have the necessary tools and expertise to properly diagnose and repair the issue.
The resistor size for the water separator circuit on your car will depend on the specific make and model of your vehicle. It is important to use the correct resistor size to ensure that the circuit functions properly and does not cause problems such as the water bleed light coming on.
To determine the correct resistor size for the water separator circuit on your car, you will need to refer to the wiring diagram for your specific make and model. The wiring diagram will show the size and location of all the components in the circuit, including the resistor.
If you do not have access to the wiring diagram for your car, you can try contacting the manufacturer or a dealership for more information. Alternatively, you can have a qualified mechanic inspect the circuit and recommend the appropriate resistor size.
It is important to note that working on the electrical system of a car can be dangerous if you are not familiar with the proper procedures. If you are unsure of how to determine the correct resistor size or how to install it, it is recommended that you have the work performed by a qualified mechanic to ensure that it is done safely and correctly.
If there is no spark coming from the coil on your 1987 Mazda B 2600 with a 2 barrel carburetor, there could be a few potential causes. Here are a few steps you can try to troubleshoot the issue:
Check the ignition control module: The ignition control module is responsible for generating the high voltage needed to create the spark in the ignition system. If the module is faulty, it can cause a lack of spark.
Check the spark plug wires: The spark plug wires carry the spark from the ignition system to the spark plugs. If the wires are damaged or not connected properly, it can cause a lack of spark.
Check the spark plugs: The spark plugs are responsible for creating the spark that ignites the fuel-air mixture in the engine. If the spark plugs are worn out or damaged, they may not be able to create a spark.
Check the ignition coil: The ignition coil is responsible for creating the high voltage needed to create the spark in the ignition system. If the coil is damaged or not functioning properly, it can cause a lack of spark.
If none of these steps help resolve the issue, it may be necessary to have the ignition system checked by a mechanic or repair shop. They can test the components of the ignition system and determine the cause of the lack of spark
It is possible that the black wire that is connected to the little black box on the side of your distributor could be causing the lack of spark in your ignition system if it is broken or not connected properly. The black wire likely carries a signal from the ignition control module to the ignition coil, and if it is not functioning properly, it could prevent the ignition coil from generating the high voltage needed to create a spark.
To troubleshoot this issue, you will need to repair or replace the broken wire and ensure that it is securely connected to the little black box on the side of the distributor. You should also check the connection between the little black box and the ignition control module to make sure it is secure and functioning properly. If the issue persists after repairing or replacing the wire and checking the connections, it may be necessary to have the ignition system checked by a mechanic or repair shop to determine the cause of the lack of spark.
no, no and no, the PCM not bad., no miles told. 300K?
INPUTS TO IT ARE WRONG. and 50 things it can be..
PCM is computer and GIGO rules (garbage in nets garbage out)
check fuses yet,? scan he PCM OBD2 port for DTC errors yet?
we do tests using tools and meters, and gauges to find the truth.
spark to all spark plugs matters most all of them not just 1.
if it had spark and timed right, the engine runs on test fuel (spray) for 3 seconds.
2.3L I4 engine ,chain cam drive, is maybe good. but if was bad the noise from it is crazy loud, and never ignored.
engine good, spark good, fueling good, is the order for diagosis
see Scotty , cranks but does not start
https://youtu.be/064Ilsz8Fzg
the fuel dribble test only finds a dead pump and never finds
fuel pressure too low, only rail fitted, fuel gauge finds that (a tool)
even too high is possible (jammed FPR)
