i was driving my truck tonight and all of a sudden it just quit and shut off and i couldnt get it started and i had to have it towed to the garage to have my mechanic look at it its a 1999 f150 4.6l with 80000 miles on it what could be wrong with it it was still moving and was running fine right before it quit

what could be wrong with it?

It could be something to do with the fuel. Like if the fuel filter or fuel lines got clogged your engine would just stall and stay that way until the clog is fixed. Happened to my cousins jeep.

it wont start and the lights dim when you try to start it and the collant resiovior is filled with a brown foam and its not from oil cause i check the oil everyday and it hasnt gone down any

Good old Bill

Did anything electrical work when the engine shut off? Radio, lights, or was it all dead?

I am assuming that it will at least crank, An engine has to have three things to run, fuel, air and spark. Start by checking for fuel, turn the key on and push down on the pressure relief valve on the fuel rail, looks like a tire valve on the passenger side. Carefull as the pressure is high and fuel will go every where if pressure is good. Then check for spark Pull the easiest COP, put a spark plug in it, DO NOT HOLD ON TO IT WITH YOU BARE HANDS, unless you enjoy that sort of thing lol, put the end of the spark plug near a bare metal area. Have somebody crank it over, you should have spark. If both of those are good, you have a bad sensor. Best thing to do is pull the codes, that way you are not spending a bunch of money changing good stuff, to me thought sounds like either the fuel pump or the mass air flow sensor crapped. Also check the fuel shutoff switch under the glove box, sometimes those go bad.

Anything electrical quit working before the truck quit running? I had a vehicle that before it shut down, the radio quit playing, and heard some other beeping from behind the dash. turned out to be a bad alternator draining the battery then it just died.

When did you look at your resevoir last, has it always been a brownish color, was the fluid inside brownish or just the inside of the jug have the brownish film on the inside?
