2003 Expedition. Fuel system loses pressure if it sits for a while w/ engine turned off. Symptom: Crank for several seconds (5-10) to build up pressure, re-crank & engine will start immediately. ...


seem to get this problem with the 4 litre jeep engine where you have to crank for a second then twice and it starts on teh thrid crank ,and i havent been able to fathom it out as yet ,but the explorer has a electronic voltage switch on top of the tank thats is operated by the immobilisor ,So what i would do here is to remove the fuel tank and join the two big wires together which effectivly by-passes this switch and i think this may cure your problem .Lower tank on a jack a bit then disconnect the multiplug and the petrol pipes ,join the two wires on this switch which is on top of the sender /pump unit ,pump the fuel out to lighten the load using the fuel pump with two wires to it ,then lift tank back up and reconnect ,good idea to remove the sender unit and check the gauze filter on the end of sender unit whilst you have it out .and check for rust in the bottom of the tank

I have a 2005 Malibu V6 LS. Whenever I fill the tank with fuel(completely full) the engine light comes on and stays on for a couple of days. This causes problems with my remote starter - it doesn't work...


your car has a fuel level sensor on the fuel pump which is in the gas tank that is going bad this makes your engine light come on also makes your gas gauge read faulty, I think you can buy the fuel level sensor seperate from the fuel pump but i am not for sure my wifes car does the same thing i just havent got around to fixing it yet but when i do i will repost and et you know.

Having difficulty filling gas tank of my 2004 Suburban at gas station. The gas pump constantly clicks off. Cannot fill at normal speed. I have recently had the check engine light appear -- stating that...


You may have a fuel tank vent valve that isn't working. This valve lets air into and out of the fuel tank as fuel is added to the tank and then later used by the engine. If the valve won't open or is plugged with dirt/dust/debris then it's becomes very difficult to add fuel to the tank. This problem would also cause the EVAP system to fail a self test and turn on the check engine lamp with a related service code. Often there is more than one reason a particular code like this can be set, a loose fuel cap being just one of them, and it takes a bit of testing to determine the exact cause. A good service facility should be able to test the system and determine what is wrong fairly easily on this one. Good luck, hope this helps.

Am told I need to replace my charcoal canister for about 500 dollars. Gas tank is hard to fill. Auto nozzles will not stay on when filling. Engine service light is on as well. Was told by dealer that this...


A few things to try...if you are in a self serve state, When filling the tank, insert the nozzle the least that you can, use the slowest dispensing speed possible. As far as the canister, it can become faulty from "topping" the tank off. Fuel gets in the canister. Service engine light is on probably because of the canister fault. But to make sure, have your local auto parts superstore scan for the fault codes...usually free of charge. Hope this was helpful.

Did you have the fuel pump changed? They might of bent the electronic float assembly in the gas tank causing it to read 3/4 full.and making the check engine light come on.

Who's to say it didn't contain some water, dirt , or other contaminate ? Wouldn't be the first time water was found in fuel or dirt or whatever. Could have faulty ground tanks, or a bad load of fuel was dropped off. Call or go to service station & let them know, as well as ask around if anyone else in your area filled up there and had problems. Did you try a little additive (HEET") or similar in tank to remove moisture , just to see if it helped at all?

Take it back to where you had it serviced. They probably simply missed connecting the fuel level sensor. The engine light is probably from a missed emissions hose that goes to the gas tank.
