2004 Mazda B3000 Problems
Water intrusion into a connector 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.
The Check Engine Light may come on and the engine will run poorly. During diagnosis the technician may find a trouble code for the Camshaft Position Sensor (CMP), P0340. It is recommended to check the CMP driveshaft for looseness in the housing because if the shaft is loose, a new sensor will be damaged again. If the shaft has play, the CMP sensor and housing unit will need to be replaced. Our technicians recommend using the factory type timing tool for the replacement procedure.
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.

I purchased a Mazda B3000 in 2004. Since day one I have had sporadic staring problems. Every once in a while when I turned the key to start it nothing would happen. After trying a few times it would finally engage. Took it to the dealer during the warranty period and it would work fine. It does not appear to make a difference warm or cold the same thing would happen. Is this a starter or ignit...
I have a Mazda B3000 2003 1st truck I ever owned and love it but the electrical was a problem. The battery it comes with doesn't put out enough so I had to mount a bigger better one & never had a problem since with the electrical. The gas tank has some weird collapsable hose that recently went out but other then those two things it's been great
