Hi Gerrie1974-
WildBill49 here......Not knowing the specific year and version of your Mazda, I cannot give you a specific part at fault, but I can help you. I am assuming we're talking about an electronic distributor single coil ignition system
If the spark is weak directly out of the coil (with a known good coil hooked up with correect polarity), then the problem is in the spark trigger module... There is a variety of designs, but the basic components remain the same. This is the part of the ignition system that replaces the breaker points. It consists of two parts - a magnetic spark trigger sensor, and a spark signal amplifier/controller. these are sometimes combined into one ignition module.
Replace this module, and spark from the coil should be strong! If it is still weak, reverse the two wires to the coil.
Weak spark at the plug wire with the above good indicates distributor cap/rotor replacement time...
Gerrie, I hope this is what you are looking for, best of luck, and if you feel my advice worthy, please rate it!!!
Thanx-

fuel pump located inside petrol tank,
you have to remove the fuel tank, only 4 bolts, and a few pipes.
befor doing so, check fuel pump relay located in the middle of dashboard on the floor(horse shoe type plastic cover)
