What is the make, model, and year of the tractor? The throttle on my tractor simply sets the amount of fuel going to the injectors. It is not a speed control. I did not pay money to have speed control. It does exactly the same as yours.

SOURCE: my driver side seat will not move forward or backward

Can you hear the motor turn when trying to go back and forth? If not, motor may be faulty or bad relay in the wiring to that motor.
If you hear motor and seat doesn't move, then the motor may have fallen off track

SOURCE: fuel gauge keeps going up and down, it goes back

The fuel gauge sending unit has failed and is driving the gauge erratically. It's in the tank, attached to the fuel pump. Replace that and you'll be good to go.

all later model chevy vehicles are plagued with this problem it,s the fuel level sensor mounted on the fuel pump module inside fuel tank unfortunately on some models it,s only available with purchase of whole new fuel pump module that can run as much as $500.00 dollars for just the module not including labor to drop fuel tank and replace I encourage you not to waste time and money with aftermarket less expensive pump module assemblies not to knock any parts people but our shop just installed the 3rd napa fuel pump module in a 98 blazer because the new pump will not read correct amount of fuel finally it was replaced by a pump module assemblie from dealership at cost of $458.00 for pump it now reads correct hope this helps if you need more detailed instructions on how to replace repost at fix ya thanks

SOURCE: Can't pump gas into tank.

You most likely have a plugged EVAP system vent valve and/or a charcoal vapor cannister. If either one is plugged then the air trapped in the tank can't get out as you add fuel. The fuel will back up in the filler neck and cause the fuel filler nozzle to kick out as you are attempting to fill the tank. The vent valves are prone to plugging if you drive on a lot of gravel or dusty roads but I have seen them plug up even on vehicle that never leave the asphalt. You may need to go to a good service facility or dealership to figure exactly out where the problem is.

well, i assume you did a compression check and have the plugs gapped properly? Okay then, this might not be what you want to hear but, disconnect the fuel lines, install a low pressure electric fuel pump(between 3 and 10 psi one) and install a variable pressure regulator, set it at 4psi and drive the truck. still need more power move to 5psi, adjust untill your happy.

Sounds as if you have been thinking the issue is fuel related, but what about spark? Bad ignition module or coil? (can be tested at parts store). Vacuum leak? Test with vacuum gauge.

Try changing the fuel filter. If it clogs up the engine won't get the fuel it needs to run at wide throttle openings, the engine will ****** the timing, and you'll lose power. With less throttle the filter can flow well enough for the engine to run properly.

CVT problem


Simple answer, no, it will not most likely cause any increased wear to your engine or transmission. Yes, it is normal for the engine to rev while climbing a hill while in cruise control.

The cruise is designed to be used on flat (or semi-flat) stretches of highway at 55mph or higher so you don't have to hold the fuel pedal the whole time and your foot doesn't get tired. The cruise control system will try it's best to keep your vehicle rolling at the set speed, increasing/decreasing the throttle to compensate for changes in engine load.

If you are driving with cruise on, try lightly putting your foot on the pedal and you might notice that the system will actually move the pedal itself. If you are in cruise, and you come up to a large hill, try putting your foot on the pedal and getting it up the hill on your own w/o cruise then resetting cruise once you are off the hill.

Also, cruise is not supposed to be used in moderate/ thick traffic or on country roads with a lot of rolling hills. The cruise control system is a "dumb" system meaning (not that it's pointless) but it will only change the pedal as the speed changes and it has no idea what's coming up next, even while you are already on the hill.

So, it is normal operation of the cruise control to try to compensate for a hill by constantly revving up the engine and letting it fall back down to try to keep moving at the exact same speed you set it for. If this is a bother, you can always use your foot to hold the pedal while climbing the hill normally.

Don't worry, it won't cause any increased wear and tear on your vehicle. I hope this helps. Good luck and don't forget to rate! Thank you!
