2000 plymouth voyager. 2.4L. wont start when gas gauge reaches 1/4 tank. within the last couple of wks ive noticed that it idles high when you first start it and now it wont start when the gas level reaches 1/4 tank. if we put more gas in it, it will start. what would cause this?

You most likely have to remove the filler
hose, to drop the tank,so syphon the gas
directly from the tank with the hose off,
where ever your going to remove it from

sending unit in tank or gauge on dash may be faulty
check engine light should come on if engine dies

my 2000 Dodge Stratus 2.4 while idling, the engine seems to surge

It sounds like the sending unit has a dead spot on it causing it to read inaccurately. The tank would have to be dropped and the sending unit replaced. Check out this page and illustration to better understand what's going on. "How a fuel gauge works"

You need to check your main fuses under the hood first and then check them under the driver side dash board.

You have a bad ground, probably at the sending unit on top of tank. Check all fuel system grounds.

when u run out of gas this overheats the in tank electric fuel pump, if the pump is already worn by high miles and running below 1/4 tank of fuel then it fails, you will need to replace the in tank electric fuel pump.

check fuse for gas gauge. or if your gauge is inside the tank, you may have to replace the tank

what kind of vechile is it

remove belt and check the pulleys. this belt routing is odd and its very tight. i have seen many failed tensoner pulleys on these. it should spin smoothly and quiet. and grinding or bumpyness in it and i would replace it. check all pulleys while your there. they are not expensive.

good luck,
Michael
