Mazda B4000 Repair and Maintenance

A guide to problems, costs, maintenance and repair for your Mazda B4000

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.

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.

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.

if your transfercase motor goes out. dont by another one. i can give u an easy fix.... and it ony takes 30mins r less 2 fix.

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 senso...

Automatic transmission sucks
