SOURCE: 2001 mazda protege will not start

well, with all that you have changed the only two possible things that are left PCM and the ECM....

Do you have an alarm system on this vehicle? If you purchased this car second hand it may have something that is inhibiting the engine from firing. From what you have told us here that would be where I would start looking.

I really hope this is helpfull

SOURCE: 2001 Mazda MPV upper front oxygen sensor change

I replaced this sensor about 6 months ago. (If this is the sensor that is located near the firewall on the exhaust manifold under the ignition coil.) The only way to easily replace it, is to remove the MAF and air filter assy. then remove the intake plenum, remove the ignition coil, and then you'll have access to the sensor. You'll need a sensor removal socket. If the socket slips around the hex of the sensor, then you'll need to use a regular deepwell socket and cut the cable from the top of the sensor, or use a combination wrench that will fit it.
The most difficult part of removing the intake plenum is getting the nut loose from the EGR valve. DO NOT just remove the two bolts holding it to the intake plenum. It will not line up correctly during re-assembly and may not seal tightly either.
This took about a Saturday to do. You'll need new plenum gaskets to replace the old. While your at it remove the throttle body and clean the carbon from the ports that lead to the EGR valve and replace that gasket as well. The gaskets will run about $30.

SOURCE: Need to replace 2001 Mazda Protege Oxygen Sensor

The front O2 sensor is located at the bottom of the heat shield just before you get to the exhaust. It has a wire connected to it. You will have access to this from the top of the car.You may need a O2 sensor tool that you can borrow from most major auto parts retailer. Disconnect the battery first then unplug the sensor. Using the O2 socket remove the sensor. The sensor should come with a packet of anti seize, apply it to the threads and install it. Plug the sensor back up and connect the battery and you should be done. Good luck.

There should be a line connecting the solenoid of the transmission to the ECU. It could be the wiring is bad or the contacts need cleaning or the IAC valve may need cleaning or is not working.
