2003 Mazda B2300 Problems

Crank but No Start Condition

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.

Check Engine Light Illuminated, code P0340

The Check Engine Light may come on with a trouble code for the Cam Position Sensor (CMP), P0340. This can be caused by the negative battery cable being too close to the sensor. The cable should be repositioned, clear the trouble code, and verify that the cable is causing the problem.

Runs Poorly, Possible Check Engine Light

A dirty, or contaminated mass airflow (MAF) sensor can cause the engine to run poorly. There may be a Check Engine Light with trouble codes relating to the MAF sensor. In some cases, carefully cleaning the sensor element will fix the problem, but replacement may be required.

I've owned several Ford Rangers and was looking for a 4 cyl 5 speed. Found it to be a Mazda b2300 and bought it. Having trouble with the cruise control working, checked fuse and brake switch. Any suggestions? Tony
Very reliable.. However, there is a constant rattling noise as if a shock absorber is going out. I can not determine where exactly the sound is coming from. Also, first gear disengages/pops out sometimes when releasing clutch.
