Re: fuel system problem
ARE YOU SURE YOU REPLACED ALL THE FUEL FILTERS? SOMETIMES THE CAR MAKERS LIKE TO STICK A FUEL FILTER INSIDE THE FRAME BACK BY THE FUEL TANK, ALSO 93 WAS STILL CARB. RIGHT. WHAT ABOUT DRAINING THE FLOAT BOWLS OF ALL THE WATER AND DIRT IN THEM? AND DO THEY HAVE INLET FILTERS ALSO? WORST CASE HOW ABOUT THE IN FUEL TANK FILTER. THIS WOULD BE ABOUT RIGHT FOR THEM TO ACT UP WITH WATER AND DIRT.IT REALLY SOUNDS LIKE A FUEL PROBLEM WITH WATER CLOGGING A FILTER AND CUTTING OFF GAS MOMENTARILY. TIME TO CHACE THESE DOWN ONE BY ONE. LEAVE THE FUEL TANK FILTERS TILL LAST, THE'RE NASTY TO DO. UGG! HOPE THIS GIVES YOU SOME IDEAS AND IF YOU NEED MORE HELP, REPLY TO:ARCLIGHT1217

you need to check fuel pressure with a pressure gauge to see if its within specs.it should be around 35psi and no lower then about 32psi.your problem sounds like a fuel pressure problem and the pump should be changed as well as the filter, but check to make sure the fuel filter is not plugged as this can also cause a pressure problem.
possibly camshaft position sensor in the distributor, or weak fuel fump starts acting up when warm, or throttle position sensor. heat has a effect on sensors and electrical components in some weird and hard to find ways.
Does the fuel gage read any higher now that you put fuel in it? If so, It was probably out of gas like you suspected. However, running a vehicle out of gas is extremely ******* fuel pumps. If your fuel pump was worn, with a lot of miles, it is probably toast now.
I have a 1986 325e with high mileage 275,000. Car starts fine and idles ok. I'm experiencing an intermittent problem where when placed in drive the car will sputter, lightly backfire, and not move forward until i pump the gas and give it time to correct whatever is not operating properly. Then it runs just fine. I'm thinking it's an air or fuel issue. Just recently tuned up the car and put some bgk44 after the problem started but still experiencing the same problem.
sounds like you need a tune up. start with a fuel filter, spark plugs and wires. it would also be a good idea to run some seafoam through the gas to clean the fuel system after you put in the new filter.
if you have an electric fuel pump that would explain the hum. unhook your incoming fuel line and blow the line clear, sounds like you've got some junk in your tank.it'll build up on the screen in the tank then fall off (at least partially) when your making turns or hitting bumps or holes. next time it's only got a gallon or so of fuel i'd drop the tank and check the pickup tube inside. sux but that's the only way to get to it. while you've got the tank off and out from under the jeep, might as well clean it out real good and replace anything inside (usually the screen) that doesn't look right, dirty etc. wouldn't hurt to run a bottle of fuel system cleaner in the next full tank of fuel either. preferably as soon as you put your tank back. good luck
This is water in your fuel lines. when it was very cold, the water in the lines froze. when it melts, it runs to the injector system and causes these types of things to happen during acceleration. i would pick up some techtron. ths is good stuff. it will remove the water and, clean out the fuel system.
