Where are the spark plugs located? Also where is the loation of the fuel filter/

I would first start with the coil, distributor cap, rotor, spark plugs, and the spark plug wires. If that doesn't fix the problem, I would then change the fuel pump (located in the gas tank) and the fuel pump relay switch (located in the kick panel on the driver's side). If that still does not fix the problem, I would change out the Air Flow Sensor (located on top of the air filter box), and the Fuel Sensor (located where the air filter tube attaches to the intake manifold).

Hello: There should be a white placard under the hood giving you the spark plug gap, Its called an ession label for your engine, the gap probably is .060 of an inch. The fuel filter should be behind the fuel tank or to the passenger side under the rear of the car.

I suggest a full tune up.

1. Air filter.
2. Fuel filter, carbureted engine filter is located inside the line fitting where it attaches to the carburetor. Fuel injected engine filter is located in-line under the truck near the tank.
3. Oil and filter.
4. Spark plugs and wires.
5. Distributor cap and rotor if applicable.
6. PCV valve.

plug gap 0.044 inch
The fuel filter on most Mazda cars can be located on a bracket in the left rear of the engine compartment, next to or beneath the brake master cylinder fluid reservoir.
Looks like this:

I have replaced Distributor cap, rotor, wires, and spark plugs in my 2000 Oldsmobile Bravada AWD smart track. To replace one spark plug I had to collapse the steering column, but everything went O.K. Did you marked the wires?. Did you reconnect them in the firing order?
The fuel pump is located In the fuel tank. Remove the fuel tank and take the fuel pump out from the top. This is part cost $300 and need some skills to be replaced.
The fuel filter it is directly in front of the fuel tank. Another one is incorporated with the fuel pump.

TO REPLACE SPARK PLUGS YOU REMOVE COIL PACK MOUNTING BOLTS THEN REMOVE THE COIL PACK WITH BOOT OVER THE SPARK PLUG.YOU HAVE 6 INDIVIDUAL COIL PACK TO EACH CYLINDER. YOU NEED A 3/8 RATCHET WRENCH - LONG 3/8 EXTENSION -SPARK PLUG SOCKET - SPARK PLUG GAUGE.AND TORQUE WRENCH.THE 2000 MODEL JEEPS FUEL FILTER INSIDE THE TANK.1993 - 1996 MODEL JEEPS FUEL FILTER LOCATED LEFT SIDE OF THE VECHICLE NEAR THE FUEL TANK.

Well if it is cranking you need to see if you are getting spark and fuel.....Try turning the ignition on without cranking the motor....You should hear your fuel pump making a whirring sound for about 3 sec.and then shut off...If no sound from pump (which is located in the fuel tank) check the fuel pump fuse If fuse is good check fuel pump relay...If all checks out ok with fuel pump take into consideration when the fuel filter was changed last....I dont recommend adding fuel injection cleaner to your tank without first changing fuel filter...additive is designed to break up debris thus breaking up all trapped particles in filter sending debris through your injectors.... To check for spark pull the #1 spark plug wire and place it on an angle on tip of plug (allowing you to see if spark is present) have an assistant crank engine while you look for spark..... Do not hold spark plug wire in your hand while engine is cranked.... I hope this has helped you

I agree. Try replacing the spark plugs, install new spark plug wires, change the air filter, change the fuel filter, and test the battery and alternator. Run a bottle of fuel system cleaner and water remover through it. To replace the spark plugs you'll most likely have to go through the wheel wells cause of their hard accessibility from the top. The fuel filter is located on the inside of the frame on the driver's side. Hope this helps. God bless

They go into the cylinders through the middle of the valve cover.

It is small and round (2 wire connector) and located either in the flexiable air intake hose to the engine or in the engine air filter housing.
