I really Need Help.

I finally got my jeep running and took it to school a few days ago. At lunch, we went on a powerline trail (real, real muddy) and got real stuck. When we were come alonging it out, a buch of mud and water got kicked up into the engine compartment. It slowed down for a minute and made some funny sputtering noises, so I gave it a break and let it idle for a little while. It ran fine and we drove to a gas station to meet some people. As I was pulling out of the gas station, it just cut off. It had plenty of gas, so I waited about twenty minutes and it started. The next time it cut off we had to use ether to get it going. I got it home and it ran fine going home, but wont start again. Itll crank, but the battery's nearly dead so Im charging it. I didnt know where to start, so today I replaced the fuel pump and filters (no gas was coming out of the fuel line at the carburetor), but it still wont spit out any gas.
I dont know what to do, so I really need any advice.

Thanks,

Re: I really Need Help.

so the new fuel pump isn't kicking out any gas? if not then either the new pump is bad(it can happen) or you are out of gas, provided you are checking the gas flow BEFORE the filter.

1: Disconnect fuel inlet line from fuel pump
2: if NoGas @ FuelLine then
Apply vacuum (not with your mouth unless you HAVE to)
If Draw Air then
Check FuelLine for cracks or disconnections in the fuel line
If Draw Gas then GoTo 3:
If Draw Nothing then
Check for plugs, mud/rocks in the gas tank maybe
3: if NoGas @ outlet of FuelPump then
Check Ensure FuelPump = Good/Working

Huh.

Maybe JeepChick is right, I do talk funny after I have been coding all day.

Anyway, good luck let us know what you find.

Re: I really Need Help.

you may have gotten some crap in the return line or on some rigs the vent at the rear. try taking off your gas cap, and try to start it, and see if that allows it to start up.

Re: I really Need Help.

I think RedSand is on the right track. Considering how old your jeep is, the fuel hoses are most likely just as old. A common problem is the fuel line get old and hard. Soon, it starts to suck air, however, it won't let gas leak out. More than likely, while you were down in the mud, something moved one of the rubber fuel lines enough to open up a small crack to let air in. In other words, it acts just like a vapor lock.

For anyone that has a jeep older than 10 years, I highly recommend replacing all your old fuel lines. How many of you are still running the original factory fuel line between the gas tank and the chassis?
