Has fuel pressure but not getting gas - 1999 Dodge Durango

Could be a "fuel pump relay" or ford equivalent that converts ECU fuel output demand signal to power to the fuel pump. To test jump direct positive to fuel pump and see if you get pressure at the rail. If you get pressure, that may be part of the problem. If not enough pressure (but measure) you may have a fuel pressure regulator or ford equivalent issue.

Yes it can if it can't maintain the correct fuel pressure. I would also check that the injectors are getting a signal from the ECM.

Check fuel pressure regulator vacuum hose if it's got gas in it the
fuel pressure regulator is bad and will need replaced. Will get into oil through vacuum hoses

Hey jessica, from what you describe it sounds like a fuel pressure problem. A vehicle can have "weak" fuel pressure & may still be drivable but will not perform well on a hard acceleration. First get the fuel pressure checked and PLEASE go to someone who will use a fuel pressure gauge not stick a screwdriver in the test port and see if fuel sprays out! I believe the fuel pressure spec. for this vehicle is 55-60 psi with the key on. The codes po171,174 indicate "both banks lean" which could be caused by a lack of fuel pressure. These codes can be caused by a M.A.F. sensor problem (Mass Air Flow sensor). Common problems with M.A.F. sensors - they can get dirty and not work properly. I still highly recommend the fuel pressure test first! If it lacks pressure you know you have a bad pump. If the vehicle has a replacable fuel filter this needs to be checked & or replaced then re-check fuel pressure. If fuel pressure is OK then check for problems with the M.A.F. ( Dirty, Air leaks between sensor & engine throttle body, defective sensor) Hope this helps!

Sounds like a fuel problem, not enough gas getting into cylinders to burn. Have the fuel pressure checked with a fuel pressure gauge. Correct pressure in the fuel rail is critical for the injectors to spray enough gas. If pressure is low, possibly a weak fuel pump or partially clogged filter. When fuel pressure is tested, the fuel pressure regulator can be checked as well.

On the back of the engine there is a fuel pressure valve. Take the cover off and screw on a hose(like the one from the fuel pressure tester, or if you have an old air hose that has an end that screws on to a bike tire valve stems , that is the size of the the fuel pressure valve) Anyway, after you get a hose that you can screw on the pressure value, just turn your key to the on position, don't start it, just turn it so the fuel filter will kick in. The fuel will flow right out of the hose. So get some gas cans or whatever you are going to put the gas in and make sure you keep the end of the hose where the gas is coming out lower than the level of gas in the tank.

You have to check the pressure of the fuel, most pumps will pump fuel when they are bad. The problem is not enough fuel pressure.

If you have gas spurting through the valve when depressed, you fuel pump should probably be alright-but that can only be determined with any certainty with a fuel pressure tester. I would think it the volume of fuel was a decent amount, your pump is alright. When you try to start the car you should NOT step on the petal-that shuts off the injectors.

Does it even sound like it wants to start? Or does it just crank?

No there is not a place to put gas when you run out of it under the hood.. You are using a fuel injection system and you are thinking carbeurator... If you ran out of gas you will be able to get fuel pressure back in the fuel rails by turning key on and off.. but not in the crank position. You will hear the fuel pump priming.. just make sure that the fuel rails are full of fuel... and water mixing with oil?? if there is water mixing with oil in your system i will assume it is coolant.. and i will say head gasket. It is fairly expensive so if you know someone i would suggest to get them to do it... You can do a oil pressure test and see if your oil pressure is in spec.. and pressurizing the cooling system with a pressure guage to see if the cooling system holds pressure.. my guess is is that it wont

CHECK TO SEE IF YOU HERE THE FUEL PUMP START AFTER YOU TURN THE KEY ON. FUEL PUNP, FILTER, FULE PUMP RELAY.
