Just a guess, but check the fuel filter. Clean it if you can or just replace it. I have had a similar problem with a different vehicle, and after doing everything else it turned out to be a 99 cent fuel filter.

I would try backing out the air/fuel mixture screw about a 1/2 a turn. Sounds like you have a rich mixture, those back fires you hear are unburned fuel.

Its either under the seat at the back or if it has a dry box on the front its inside there. It could be under front fenders on right hand side. Hope it helps you out..

Are you sure the water pump has failed? Read this: sporadic heat spikes, no visual movement of water in radiator, no fan running, overheating light on and off

These are just a few, but they all boil down to no water movement, like a thermostat or water pump failure. Of course there is also the possibility of a bad thermostat switch (bottom of radiator), bad thermostat even a bad overheating switch (back of rear cylinder near water inlet.)

You can check the fan switch (bottom of radiator) by noting that it just give the fan a ground when it switches. So disconnect the line from the fan to the thermostat switch and ground it (the fan line), the fan should turn on. Thermostat can be placed in a pan with water and heated to ensure it opens. The other switches are checked by ohm meter since they close when it's overheated.

We replaced most of these parts also. Further investigation shows that we were not getting water flow. The thermostat has a hole in it for relieving the system of air. The air can cause the pump not to work and no water flow. So we found that the thermostat was put in upside down so the hole with the partial rivet was at the bottom. Drill a hole in the top of the thermostat, 1/8 inch, ensure you don't drill where the thermostat closes and seals or where it will be covered by the gasket or sealant.

Put the stuff back together, fill radiator, while filling remove the dark bolt on the intake manifold near the center and purge the air out of the system while filling the radiator.

Check for leaks after starting and as you drive it to warm it up feel the radiator for a slow warming, not fast high heat changes, this is a problem. Hopefully when it gets hot the fan will run on and off properly. This should a proper fix.

Hope this helps.

could be as simple as the plug caps or maybe coils are old and crusty by now. you really should get a service manual for it for easier troubleshooting. i do not suggest reliable store. factory is the best

I work on 3000 and 4000 mules at my job. when it runs bad it can be to coil. Each cylinder, which is 2, can be the coil for that plug. What I do is pull the plug on one cylinder. If it crank then I pull the plug on the other cylinder. if it will not crank I know it is the coil for that cylinder.. It might be the plug, change the plug then change the coil and wire.
I hope you know when I pull the plug on one and it cranks and then I put the plug back on for that cylinder and pull the plug for the other cylinder.
