Mazda B4000 Problems

Engine -- Verified

Water intrusion into a connector (X309) located under the cab, beneath the driver's seat, can cause a rough idle, erratic speedometer operation, ABS Light and Check Engine Light illumination, and automatic transmission shifting problems. If needed, connector repair parts are available from Mazda dealers, and possibly some Ford dealers.

Engine -- Verified

If the engine cranks but does not start, it may be caused by a tripped inertia switch. Switch the key to "ON" and the fuel pump should be heard running for a second or two. Listen at the gas filler if necessary. The inertia switch is located on the firewall and can be tripped when the parking brake is set too hard and then released. The inertia switch should be reset, and will click when it is reset.

Engine -- Verified

The engine may fail to start due to an electrically shorted sensor. Some of the sensors may internally short and not blow any fuses. A technician may find no spark and no operation of the fuel injectors in the diagnosis. One way a technician may isolate the defective sensor is by disconnecting sensors one by one to see if the engine starts.

Engine -- Verified

A dirty, or contaminated mass airflow sensor (MAF) can cause the engine to run poorly. The Check Engine Light may or may not illuminate.  MAF sensor related fault codes P0102 and/or P0103 may be stored. In some cases, carefully cleaning the sensor element will fix the problem. If not, replacement of the sensor may be required.

On some tires, under extreme conditions, the tread could separate, which can cause immediate tire failure. This may lead to a loss of vehicle control, injury, and death.

when started the car when it get hot it shorts down my light in my dash saying check engine n check gauge n battery light on when it diet is that my problem I have no ideal what the problem here that my ruck diet. okay thanks

I love my p.u. I have kept up maintenance etc and it has always run beautifully, until 2 months ago. When I slow down to stop at a light or stop sign, or to make a slow turn, it starts pulsing and dies. Starts right back up no problem. Have cleaned and changed everything anyone suggests. Three experienced mechanics are stumped. One just quit, doesn't even want to see it again. Not the sensors, fuel pump,intake manifold gaskets several other things I can't remember right now. When driving on the freeway or any where, it is fantastic, only when I slow to stop does it do this. Any ideas?? Grannie

I love me truck. However recently it stallesd, I had to wait 5-10 min for it to restart. Thought it was the cadiledic converter as it ran rough and the exhaust was red. Now it doesn't start when it is hot. Have replaced the oxygen sensors,the ECT sensor, ignition moduale, TPS, and the feul filter. After the feul filter replacement the truck randomly chugs whe going down the road. Still won't start when hot. I am lost but still love my truck

Bought this truck used and it has over 140,000 miles and has been great. recently rubber went bad in front say bars. Dont know if thats a hard problem to fix. anyone had to do it. Does it require alot of work.
Other than that. LOVE MY Truck.
