What is blocking the fuel from getting to the injectors?

There is enough fuel,we have put some fuel into the chambers and it does start but switches off after running for 1 minute only. According to my understanding the fuel is not being pumped from the fuel pump to the injectors.

I'm not a professional mechanic but the fuel pump does that and it has to have a clean fuel filter to do it effectively.

SOURCE: 1996 mazda mx6 ls cranks but won't start

you may need to run a wire from a keyed ignition source that has power while cranking and running to the fuel pump relay and bypass the pcm to test wether it will run, if it runs put a more permanent wire in place.Not too sure what tests youve done but it seems that fuel is what your focusing on so a quick test is too spray engine start up the intake tube to see if the engine trys to run if it does it eliminates a lot of other potential reasons for a no start condition.Also try squeezing the fuel return line to see if the added pressure will try to make engine run.Could be time to replace fuel pump etc anyway let me know how it goes good luck with it

SOURCE: dodge cummins won't start, fuel reaching injector pump but no fuel coming out of injector pump.

You said you have fuel flowing from the inlet line of the injection pump? But not at the injector lines?

SOURCE: 1991 camaro RS Fuel pump not working- no power to pump

If the oil pressure switch has two wires on it it may be one that shuts down the pump. I'm not positive but I think it completes a ground circuit, not the hot side though (but may run through a relay.) There should be a pump relay under the hood with a group of other relays. I don't have a wiring diagram for your car but you can get a basic diagram in most inexpensive manuals. They wont usually give you locations but at least you can get an idea of how the system works. There usually is a fuse. If the fuse block is not labeled, use a test light and probe the back of every fuse for power with the key on (takes about ten minutes and faster than trying to find info) change any that are blown. The most likely culprit is a relay, so after testing fuses look for it. (usually on drivers fender or on right side near firewall.) Worst case, trace the power lead all the way through the harness 'till you find where power begins.Testing is important here...I could give you much better info if I was there to do it for you. Most important is to stay "on track" till you find the place where power ends. Don't jump all over the place or you will end up doing an incomplete test.

SOURCE: How do I replace a fuel pump on a 2003 escape?

Check to see if the inertia switch is tripped first. Read your owner manual for location and how to reset. Just push the button. It usually only trips in an accident to shut off the fule pump in case there is a leak.

here is how to replace the pump. It's good because you don't have to drop the tank!

  1. Relieve the fuel pressure. For additional information, refer to Section 310-00 . (I disconnect inertia switch and crank engine for 10 seconds to revilve pressure).
  1. Disconnect the battery ground cable. (I don't do this myself).For additional information, refer to Section 414-01 .
  1. Lift the LH rear seat cushion.
  1. Position the carpet aside.
  1. Remove the screws and the fuel pump module access cover.
  1. Disconnect the electrical connectors.
  1. Disconnect the fuel and vapor lines from the fuel tank. For additional information, refer to Section 310-00 .
  1. s3k~us~en~file=ani_caut.gif~gen~ref.gif WARNING: The fuel tank may be pressurized. Remove the fuel tank filler cap slowly. If a hissing sound is heard, wait until the condition stops before removing the fuel tank filler cap. If these precautions are not followed, fuel may spray and cause personal injury.
    Remove the gas cap.
  1. Using the special tool, remove the fuel pump module. (If you don't have tool, use a chisel or screwdriver and tap counterclockwise to rotate the ring).

  1. NOTE: Install a new fuel pump mounting gasket.
    To install, reverse the removal procedure.
    • Start the engine and visually inspect for leaks.

Not a bad job. buy pump on ebay or new at discount at tascafordparts.com

Why is it not getting gas


Check to see if the fuel pump is actually receiving power and pumping the gas to fuel rail or carb.

7.3 diesel cranking over more than my v-10 is that normal


Yes, it IS normal for a powerstroke diesel to require more revolutions of the motor to fire than for any gasoline engine. Combustion in gasoline engines is stimulated by spark plugs and many gasoline engines will start with little turning of the motor past the position where the ignition timing creates the spark and combustion occurs. Combustion forces the engine to continue rotating and combustion in that and other cylinders becomes a perpetual event. A Powerstroke Diesel engine requires more revolutions and speed of revolutions to create the heat necessary to cause the diesel/air mixture to combust. ALSO, the diesel is injected into the combustion chamber, at high pressure, by the injectors. The injectors are electronically controlled and the Fuel Control Module (computer) (also known as the Injector Control Module or ICM) tells each injector exactly when to open and inject diesel into the combustion chamber, as well as for how many milliseconds it stays open (how much fuel will be delivered). Summary, a powerstroke diesel will only begin the perpetual combustion process when the motor is turning fast enough and the pistons are compressing the volume of the cylinder into the tight space of the combustion chamber rapidly enough to create enough heat for the fuel to ignite and begin creating power to turn the motor without the aid of the starter. IN ADDITION, a Powerstroke will NOT start at all with weak batteries. Not only does the motor need to revolve rapidly in order to start, the injectors require a MINIMUM voltage of MORE THAN 12 volts in order to activate (open). The exact amount of voltage required can be different, depending on the Fuel Control Module (FCM) or "Injector Control Module" (ICM) type that is installed. (Note; terminology for the FCM / ICM tend to depend on who you are talking to, what resource you are reading, etc. They are the same thing.) If batteries are weak, the starter uses enough amps to drag the voltage down and, even though the starter turns the motor fast enough that any gasoline motor would fire right up, the ICM will never send the signal to the injectors for them to activate so, the cylinders never get any fuel and the motor never fires. I hope that helps. Yes, a 7.3L diesel will normally need to turn with the starter for longer than your gasoline fueled V10.

Why is gas in oil?


Either too much fuel pressure or spark plugs are bad.

My 2001 Dodge Stratus wont start but lights inside and out will come on, but engine will not start,


It is possible that the battery may be too weak to start the car but may have enough power to turn the interior lights. Is the vehicle cranking over at all? Let me know if this helps, Jeff from fixya

My 1996 chevy blazer won't start. we changed the the fuel pump, fuel pump filter checked the relay and she turns over once we put gas in the carb. body. help please


Have you ever put in the gasoline tank any injector cleaner yet because the cleaner will unclog the injectors so full amounts of gasoline can get into the piston chambers the right amounts so try putting injector cleaner into your gas tank. When you put this into the gas tank to remember that it takes time for the cleaner to get to the injectors so you might have to keep trying to start the vehicle many times for the cleaner to unclog the injectors. This will not hurt your vehicle at all so go try this.

I have a 1997 dodge grand caravan 3.8l v6 with about 146k. I stopped at a gas station and put gas in it (was at 1/2 tank) Went to start it and it started hard. Cranked for about 4 seconds before turning...


Have you ever put in the gasoline tank any fuel injector cleaner yet because your injectors which injects the fuel of gasoline, if the injectors are not injecting enough fuel into the piston chambers that the fuel injectors needs to be clean to allow enough fuel to come in so go buy injector cleaner at autozone and put the whole thing into the gasoline tank and then drive. Your fuel injectors are clogged or going serious bad on you so you might have to replace them as well but first try to put fuel injector cleaner and see.

My 1992 dodge dakota wont run. i will start it but i will have to feather the gas to keep it alive. it has over a half a tank of gas in it can you help me?


when was this vehicle as serviced?
this could one of several issues.

1 the idle jet on the carborator maybe dirty so the engine is not getting enough fuel at tickover to keep running.
2 the fuel filter is blocking up and may need replacment.
3. the carborator may need an overhaul as the float chamber is not activating correctly.
4. fuel cap may be blocked give a run with the fuel cap off see if that helps. if you get aload hiss each time you fill up that indiates a blocked fuel cap which will need clearing or replacing.
5. dirt in the fuel line if filled from jerry cans contaminents can get in th tank and block the line. when you put pressure on the gas this causes higher vacum from the pump and hides the problem.
6 airfilter may be blocking and needs replacement so there is not enough air at ldle.
7 check plugs if they are sooty or covered in white then the mix is wrong and needs resetting. or indicats reduced fuel or air to engine.
8. plugs may need replacement.

Can not start engine, will only start after pouring gasoline in butterfly valve, runs only long enough to burn the fuel I just added. Fuel pump good, and new fuel filter.


Hi I am Vortash sounds like a blocked fuel injector or if your vehicle is not fitted with the fuel injection system a blocked main jet or fractured or perforated diagphram in the carb so as you push the accelerator the fuel is not being pumped into the inlet manifold . if carb type fitted check needle valve seat and remove main jet and clean , if non Nsu type carb check float chambers for contamination ,Check manifold seals for leakage .
Fuel Injected systems check all plugs to sensors and check air flow valve , remove plugs after attempt to start and see if wet thereby faulty pressure valve pumping too much fuel Ie : flooding . Check all plugs on ECU and throttle resistor (controller ) hope this helps regards vortash
