SOURCE: 1992 190e mercedes won't start?

it sounds like your fuel distributer is clogged. Replace your fuel filter. first you can try to bleed your system. take 12mm. wrech and loosen up you lines(one at a time) and crank your engine over(with a battery charger)and force your fuel bubbles out of the lines. while the engine is cranking and the line is loose knock on the line with the wrench and you will probably see a whole buch of rust poor out of the loose fitting. do thius repeatedly untill engine fires off-then with engine running loosen up your lines and repeat if any lines loosen up and there is no idle change that means that cylender is not firing and your injecter is not working. These mechanical style injecter's take alot of pressure to open the poppet valve to spray fuel.hope I have been helpful

SOURCE: 2000 dodge stratus 2.4L has no fuel pressure at

check fuses and the fuel pump relay if good have someone turn key in the on position with key off while you listen for the fuel pump to kick on if you dont hear anything pound on the tank with hand while the person turns it over. you might jar it to come on. if not check power to the fuel pump. Also make sure you have gas in it if questionable on how much put 1 gallon in just to be on the safe side. No I am not poking fun I see the simplest things kick our(technicians) behinds

Fuel pressure


fuel pressure needs to be checked with a pressure gauge attached to the fuel pressure testing port. it is a Schrader valve located on the fuel rail which is what supplies the injectors with fuel, it looks similar to a tire valve.

Where is the outlet to test the fuel pump on a 2005 dodge stratus


I believe you have to put a "T" in-line to test the Dodge Stratus fuel Pressure.

If there is a Port, it will be located on the Fuel Rail. Do not test the EVAP Port.

How do you check fuel pressure


You will need to rent a fuel pressure gauge from the local parts store.
Locate the fuel pressure test port, you may have to refer to service information to locate this port or you may have to T into the fuel supply line.

  • 2 Cycle the ignition key "on" and check your readings, write this number down. Start the car and run it, record your fuel pressure reading again. If your performance problem occurs when driving then you will need to take a road test to record the fuel pressure when driving. Tape the gauge to the windshield and have an assistant watch the gauge while you drive.

    Hard starting


    Do a fuel pressure leak down test, the test port is located on the fuel rail that supplies fuel to the injectors on the top of the engine, the pressure should not drop more than 5 PSI after the engine is shut down, make sure the fuel gauge (special tool) is not leaking at the schrader port connection. If the fuel pressure leaks down right away you need to replace the fuel pump inside the fuel tank, it has a defective pressure check valve. I understand you can buy a universal test gauge from most parts stores for about $20.00 that hooks up to the above mentioned test port.

    Sounds like the fuel pump is going or gone out and it trys to start but it wont turn all the way over


    By what your stating, that it starts and dies every time, It seems to be fuel related. You need to perform a fuel pressure check. You will need a pressure tester, one that would at least be able to read pressure to a maximum of 150 lbs of pressure. Although you really only need about 50-60 pounds of pressure to maintain proper fuel injector operation. There is a test port located on the fuel rail where you would conect the pressure tester. The test port is usually located on the drivers side of the engine near the rear section coming up from the firewall. Unscrew the pressure port cap if its still there and connect your tester. But also keep in mind you may have fuel pressure of some sort in the rail so be careful. While the tester is screwed to the test port you want to cycle the ignition key on and read pressure, you may want to repeat this several times. You must have at least 50 pounds of pressure, if so it should start. If you are losing pressure while your maintaining a visual check on the tester it could also be a faulty pressure regulator/fuel pump or even a rubber hose connection inside the fuel tank that connects the fuel pump to the fuel line. If you have any questions Im here to help. Thanks for using FIXYA

    Can you get rid of the fuel pressure on a 2005 I5 by just taking the fuel cap off?


    No you cannot, however there is a fuel pressure test port under the hood.
    The test port is located on the fuel supply line near the fuel injectors. This test port has a schrader style valve that operates like a valve stem on a car tire. Depress the center of the valve to release the pressure. Do this only on a cold engine and with eye protection on. It will spray 10 onces at best.
    Good luck
