An ignition coil is more than likely your problem. When the car is not running pull one spark plug wire and a plug and insert plug into the wire hold plug end on ground area. Have someone crank engine and check for spark. If no spark, replace ignition coil.
Before servicing the vehicle, refer to the precautions in the beginning of this section.
NOTE: The wheel bearings are not serviceable. If the bearings are bad, a new hub/bearing assembly must be installed.
Remove or disconnect the following:
Fig. 1: Exploded view of the rear wheel hub and bearing assembly (disc brake model shown, drum is similar)
Brake drum, if equipped
Rear caliper and rotor assembly from the hub, if equipped
Hub dust cover
Raise the staked portion of the hub retaining nut with a hammer and chisel.
Remove or disconnect the following:
Hub retaining nut and discard it
Hub and bearing assembly from the spindle
Fig. 2: When installing the new hub nut, be sure to stake it into the notch on the spindle
Install or connect the following:
Bearing assembly on the spindle. Torque the new nut to 131-173 ft. lbs. (177-235 Nm)
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)
Remove the steering knuckle assembly, as described previously.
Remove the bolts attaching the hub/bearing assembly to the steering knuckle.
the hub/bearing assembly from the front of the steering knuckle. The
bolt-in front wheel bearing used on the vehicle is transferable to a
replacement steering knuckle, if the bearing is in serviceable
condition. If the bearing will not come out of the steering knuckle, it
can be tapped out using a soft-faced hammer.
Thoroughly clean all parts, including the hub/bearing assembly mounting surfaces on the steering knuckle.
the replacement hub/bearing assembly onto the steering knuckle,
aligning the bolt holes of the bearing flange to the knuckle.
the attaching bolts and tighten evenly to make sure the bearing is
square to the face of the steering knuckle. Tighten the attaching bolts
to 80 ft. lbs. (110 Nm) on Cirrus, Stratus, Sebring convertible and
Breeze, or 65 ft. lbs. (88 Nm) on Sebring coupe and Avenger.
Install the steering knuckle assembly, as previously described.
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!!!
