what would cause a car to cut off when you go up hill.?

Question

1994 saturn sl2

Answer 1

You weren't giving it enough gas and the engine stalled? It ran out of fuel?

Answer 2

Could be "trash" in your tank, - like leaves, pieces of paper, bits of tin, bottlecaps, - and all sorts of other stuff that kids might put in filler neck (when playing), - or that adults would put in your tank when they aren't playing! Could be that the pick up line is at rear of tank and slightly above the "level" of gas tank, which would make it "slide " to the rear and get in way of pickup.

Is it more prevelant, when gas tank is near empty, or near full? Since gas will pick up at easiest place to pickup, (with no interruption of supply line), --If the fuel pickup line has a hole in it a little ways up from bottom, when the fuel slops to back, it falls below the "hole" and fuel pump will pump air esasier than gas, - as air is lighter! This is much more likely with fuel pump on engine or someware along the frame of car!

Also there is a slight possibility that you have a air leak in fuel line near the front of the car, --and when the angle gets steep enough the "head" of pressure to pull fuel uphill is higher than on the level, or going down hill. In other words, it is harder to pull fuel up to a higher level,- and again, the fuelpump will pull whatever is easiest (such as air)!

Last of all, how steep is this hill? It is possible that you have a bare wire, and it is grounding out by hitting some other metal object when the "slant" becomes enough to move wire backwards. And occasionally might make the car "jump", or "stutter" on sharp accelrataion!

I have a 22 Model T Ford, which has no fuelpump, and the gas tank is (barely) higher than the carbureter, so that the fuel will feed by gravity. If the hill is very steep, and the tank is less than half full, the only way to go up that hill is backwards! Since that makes the gas higher than the carbureter!!!

Answer 3

Coincidence? I'm not sure about the engine type, or fuel system. But If it were a carburetor I would say the float in the fuel bowl. Since this would have to be injected, I recommend you take it to a shop. They'll have to fix it any way. Does it happen a lot or is this a 1 time thing?

Answer 4

Do you have a full tank of gas? If not thats your problem... if you do then your gas tank floater might be all the way at the front of your gas tank and when you go up the hill it thinks you have no gas and no gas is going to the car... not sure...

Answer 5

SOME TIMES, NOT OFTEN MIND YOU, BUT SOPMETINES A MOUSE WILL GET INTO THE FUEL TANK AND AS IT DECAYS PIECES OF IT DECAYING BODY BOUNCE AROUND IN THE TANK TILL I GETS SUCKED UP INTO THE FUEL PICKUP.

Answer 6

fuel pump is bad
