Fuel pump not priming

  • Jan 23, 2014 · So how does one refill the large cartridge fuel filter container after changing its filter, reassembling it dry, and therefore losing the prime charge on the mechanical lift pump? After nearly killing my batteries, and going through a full can of starting fluid, I realized just cranking and short run bursts was not going to do it.
May 06, 2011 · There isn't anything that's monitoring your fuel pressure, the priming function is static - so it's not going to be anything in your fuel system. It's going to be something electronic. If fuse-able link were the cause, it wouldn't work at all. If it were the relay, then it would run all of the time when the key was off.

I replaced the fuel pump and tested voltage to the pump. Looks like the pump is never getting voltage to "prime" either at door open or ignition on. When I start the engine I get full 13 volts to the pump.

    @t663s33, Fred Clevenger, You did not state your year/make/model/engine so I will post some what generic answer on fuel issue. Ensure you have good fresh gas and that there is fuel flow from the tank, as there may be an internal screen in the tank plugged. If the engine has a fuel pump, you should not have to prefill lines/filters.

    Apr 04, 2017 · My fuel pump is not running/priming when I turn the key. I'm seeing 11.65V at the fuel pump connector (green/lack and blue/white) but nothing upstream from that point. I can power up the fuel pump using a 12V external power source (It's a jump-start battery pack so it might be more than 12V).

    fuel. The correct mounting position is even with or below the tank and preferably behind or next to the fuel tank. All electric pumps push fuel far better than they can pull (suck) fuel. Make sure that a low restriction filter is between the tank and the pump. A 40-micron element it sufficient to protect the pump from contamination such as dirt,

    Im just in the process of installing my inline Bosch 910 Fuel Pump. What i have noticed is that the factory pump does not prime when i turn the key to ignition. I've checked for voltage when ignition is on, but cant seem to find 12V on any wire going to the fuel pump, but once the engine turns over i have 12V on the wire which runs to the fuel ...

    As for the primer lever, the lever should operate the diaphram just as the fuel pump camshaft lever arm does. If it will not prime now, it likely won't pump fuel once the engine is up and running. If you cannot get the mechanical pump working, just bite the bullet and install a Carter electric, or similar.

    Jun 02, 2015 · If you are not sure, it is a simple task to do it. Remove the fuel pipe from the rubber connector pipe under the Eber. Take the cable off the pump, get two pieces of wire and connect to 12v and gnd. Hold one wire on one of the pump connections and tap the other on the remaining pump connector. Polarity is irrelevant.

    There are TONS of threads about problems with the pump not priming and I have read through mostly all of them.

    Then use the manual primer pump to prime. If no primer pump, I guess it MAY be possible to prime using the key, but that is sure iffy, particularly if the fuel has drained from primary filter back to the tank (level of fuel in the tank lower than the primary filter housing)! So, Caterpillar's official position is dry filters if manual pump, fill filters if no pump. Brett

    Majority of the time, if your fuel pump is not priming, it's the relay... The wires get disconnected under the fuse box. It's typically easiest just to jump the relay. This, of course, means your fuel pump will not shut off once it is primed. (Your fuel pump will continually run if the key is left on.) If that's not the case, try checking the fuses.

    The new pump is not drawing fuel from the tank. I took the delivery line off the top of the tank, pressurized the tank and fuel came out of the port on top of the tank. We tried to get fuel through the lines while pressurizing the tank, but we are losing pressure through the return line. This is where we stopped Friday. Our next step will be to ...

    If i am not mistaken you can do it just for a couple of seconds. Once you turn on the switch (no ignition) in some cases the pump primes for a couple of seconds then shuts down. Anoter test you can ake is place the ignition switch in the on position and then jump out the wires for the oil pressure sender, the pump should start priming.

Aug 16, 2017 · So I decided to reseal the pump and change the 2 filters at the same time. Easy enough, as I've successfully bled the system many times before when I had some dirty fuel problems. (long since fixed, cleaned tank, new lines, new lift pump and in line filter fitted, it's run for years since then, so I doubt that's got anything to do with this).

The injector pump in your 5.9 Cummins can be primed quickly. Priming the fuel system is needed when the fuel system has been worked on or if you ran out of fuel. Fuel filters should be replaced often, which require the priming of the injection pump. Priming is the process of getting diesel fuel to the cylinders.
