    • 1). Open the hood of your Mazda and locate the spark plugs. They are on the engine block.

    • 2). Attach the spark plug tester to the spark plugs. Attach one tester lead to the spark plug lead on top of the spark plug and the other lead end of tester to the engine block.

    • 3). Start the car. If the tester fires, then the problem is not with the wiring and may lie with the fuel pump.

    • 4). Replace the spark plug. Unscrew the existing spark plug with a wrench and put a new one in. Start your Mazda again, listening for any hesitation. If there is none, then the problem was with the old spark plugs and not with the fuel pump. If there is hesitation, continue troubleshooting.

    • 5). Remove the air filter. Uncap the cover on the engine side and pull the filter out. Clean the filter with an air filter cleaning kit. Replace the air filter and start the car. If the hesitation in start-up continues, your fuel pump is beginning to wear out.
