First off I need to know if this is an electronic version of the 466 or not. There's a few things to check if it's computer controlled but I won't bore you with the details until I know which you have. Write back.
Had the same problem - turned out we bent one of the prongs on the oil pressure switch when we were connecting it.
If it is not running and the fuse an relay is good it needs replacing. Even if it is running it may no be pumping. A fuel pressure test will verify if it is good or bad.
Can be a hole in the radiator or a problem with one or more of the hoses. A mechanic can run a pressure test to see where the problem(s) are located at.
sounds like a fuel problem change the fuel filter first
Just had this problem. I replaced the oxygen sensor and it appears to be running fine.
mine did that and i replaced the crank shaft sensor,problem was fixed
do a pressure test had same problem it was a bad fuel pump
Has the fuel filter been replaced?
Try getting the PCV pipe replaced. Mine had a problem with it conking-out at stops and on turns and that turned-out to be the problem. It could also be a vacuum leak.
If the heater blower has humming noise when motor is running, first check its capacitor. If the capacitor is fine, then the motor is the problem and may need to be replaced.
What year and make of car? My 1997 Honda Accord's radiator fan kept running after it was shut down. Upon inspection of my system I had low coolant and no pressure. Replaced the radiator and have not had an issue since. Check and top off your coolant, if it continues then I have no clue as to the problem.
The pressure switch that tells the furnace the vent fan has started and is running properly, did not close. Try tapping it lightly with a finger once the fan has started, then get it replaced. Follow the rubber hose from the vent fan to locate the pressure switch.
