1999 Mazda Protege How to Install Clutch Transmission Problem

I highly doubt it's a complete distributor failure. Have someone (a good shop) do a fault scan (OBII scan) and pull fault codes - then you'll know EXACTLY what to replace/repair instead of throwing parts at it.

How old is your battery? If I am having problems with starting, and my battery is getting close to 5 years, I automatically change it, as I want to have reliable starts. This usually fixes the majority of my problems. If it doesn't, I take it to the shop and have the starter checked.

Repalce the throttle position sensor it is most likely faulty, the sensor is located opposite of the throttle valve it has a few wires going into it.

first thing i would do is put the old spark plugs back in and try it [may be faulty new plug] if that doesnt work replace ht leads and all so take distributor cap off and check condition

Change out the high voltage wiring to the plugs and to the coil. If no help, change the coil. Make sure to use a clean spark plug to check the spark.

the distributor has points in it this may be your problem. what all have you replaced

I recommend that you go to any Auto Parts store and by a repair user manual for your 2000 Mazda Protege.  They have pictures and arrows and stuff that you will need to do the whole job.  The non-Mazda version will cost approximately $15.00.
Because of the tensioner that may come off when while you are doing these belt changes, it is too complicated to talk you through this.
But with the manual, I am confident you can change them.
