I have a 2003 mazda protege 5. I've changed the fuel pump, plugs, oil and filter. It just won't start. Please help.

change the transmission fluid, replace the oil and oil filter check spark plug cables, check starter coilpak, and make sure there is coolant

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

on the 2.0L it is all the way in the back of the engine just over the axle

There are two bolts on the side of the fuse itself. Under the fuse box on each side. Unbolt those and it will come out.
