If the dash lights are flickering and the gas gauge isn't working on your 1986 Mazda B2000, it could be due to a faulty electrical connection or a failing voltage regulator. Check the fuses and wiring for any signs of damage or corrosion. Additionally, the issue might stem from a malfunctioning instrument cluster or a bad ground connection. If the problem persists, consulting a professional mechanic for a thorough diagnosis is recommended.
Check the oil sending unit.
Put in a new fuel pump, it will save the time wasted on everything else
Yes, the radiator fan on a 2000 Mazda Protege should activate when the engine is idling, especially if the temperature gauge indicates that the engine is getting hot. The fan helps to maintain optimal engine temperature by drawing air through the radiator to cool the coolant as it circulates. If the fan is not running during idling and the engine temperature rises, it may indicate a problem with the fan, the temperature sensor, or the fan relay.
don't accelerate as much or change up a gear
It probably needs a tune up. My 1998 Mazda 626 was idling very rough, so I did a tune-up by replacing the spark plugs and wires. This made the engine run better, but the rought idling continued. I took it to my mechanic, and he found a vacuum leak somewhere, and $270 later, it idles smooth as glass
It is possible that your radiator needs to be topped up or that it is empty. My little 1991 Mazda Autozam Revue did the same thing so i checked the radiator and both tanks were just about empty.
