Farmtrac dtc 30

I have a 2006 Farmtrac DTC 30 with a 30 hp Mitsubishi diesel. The problem win bad fuel containing water and algae. The fuel tank has been drained,fuel line replaced,injectors rebuilt, tractor tuned on a dyno, new fuel treated for algae, fuel filter replaced. The tractor will run for 1 hr and then loses power and shuts down. In order to restart, the injectors have to be bled. I am looking for ideas as to what to try next. Ted

SOURCE: My '92 F250 wtih 7.3L diesel starts then shuts down.

92 and 97 have completely different injection syatems. I agree with the air getting into system on the 92. the fuel pump has a check valve in it' the valve may be bad allowing fuel to drain from the fuel filter housing, Could even be a pin hole in a line between fuel tank and injection pump, follow lines back to tank, see if you see any moisture on either the feed or return line, these have a history of rusting, may be a pinhole onder the rust> Let me know if this helps

Ethanol really causes problems in cars that sit around.Thanks for us going green huh?It decomposes non-metal parts in the gas system.If the car sits around for something like 6 weeks the gas does go bad.You have to siphon the tank as much as possible.When filling up,add octane boost first then gas.It still may not work though.I did all that for a scooter and it still didn't work.So if you try it,when you add gas,probably only use 4 or 5 gallons,so you don't waste too much money if it doesn't work,and it is enough to mix the octane boost fairly well.Good luck bro'!That's all i have for now.And gas is gas no matter where you buy it.All those additives the companies claim clean this or that is just sales.Since fuel injection came out,companies are required to add a certain amount of detergent to keep injectors clean anyways.And 93 octane is not better than 87 octane enough to pay 20 cents more per gallon.

take the shut off valve out of the injector pump and inside the valve is a round metal body with a rubber seal on the end ,check this seal hasnt swollen and stuck ,also check inside the primary fuel filter for any transparant pieces or crystal ,this is a problem i have been getting of late with people putting this bio fuel into the tank ,it causes this crystal stuff and it damages the injector pump as it passes through the filters and solidifies in the injector pump and kills them.just though before you start pulling it apart crack off a couple of injector pipes and get assistant to crank engine throttle wide open and see if its pumping fuel first this will give you some idea what to look for ,leave this answer in your e mail box so you can get back to me later after having a look ,but please remember the time zone difference

Fuel rail pressure too low

You didn't say whether petrol or diesel engine...

In the case of trouble or doubt regarding fuel filters it is best practice to cut open the filter and carry out a close examination for possible contaminants.

Fuel pressure is important, in fact a common rail diesel won't even start if there is insufficient pressure, but the volume of fuel delivered is at least as important as the achievable pressure - without sufficient volume the required pressure simply won't be achieved.

No fuel system check is complete unless the delivery volume has been tested and found satisfactory. If it isn't satisfactory the fuel tank, the pump screen, the pump and pipework should be checked. The pump screen if fitted is so fine water will not pass through it and so water in the fuel tends to reduce the volume.

I suggest you have the fuel system checked - properly!

I have 2008 GMC sierra 5.3 L with a new fuel pump. And no power to the pump. Any ideas where to look?

Fuel Pump Flow Control Module (FPCM) - LMF
The fuel pump flow control module (FPCM) is a serviceable GMLAN module. The FPCM receives the desired fuel pressure message from the engine control module (ECM) and controls the fuel pump located within the fuel tank to achieve the desired fuel pressure. The FPCM sends a 25 KHZ PWM signal to the fuel pump, and pump speed is changed by varying the duty cycle of this signal. Maximum current supplied to the fuel pump is 15 amps. A liquid fuel pressure sensor provides fuel pressure feedback to the FPCM.
Electronic Returnless Fuel System (ERFS) - LMF
The electronic returnless fuel system is a microprocessor controlled fuel delivery system which transports fuel from the tank to the fuel rails. It functions as an electronic replacement for a traditional, mechanical fuel pressure regulator. A pressure vent valve within the fuel tank provides an added measure of fuel pump flow control module (FPCM). Desired fuel pressure is commanded by the engine control module (ECM), and transmitted to the FPCM via a GMLAN serial data message. A liquid fuel pressure sensor provides the feedback the FPCM requires for Closed Loop fuel pressure control.

Diesel engine

no DTC posted, wow , nor year. and which Diesel.
I guess you need to understand how EFI works
in a nut shell, the EFI can compensate for weak parts.
including a weak pump.
that magic is called closed loop.
but on newer cars, the pump is monitored for proper pressure,
this is a godsend.
if the pressure drops, IT WILL GET Worse.
Great information to learn just before a 3000 mile trip, right?"
it's and early warning,,,
and can be caused by many things.
1: love voltage to pump, (bad wiring)\
2: pump weak.
3:: fuel pressure regulator stuck open (or closed of pressure too high
you never gave DTC so cant advise ,)
4: crushed fuel lines, from driving off road. etc.
some cars uses different Diesel injection systems in different countries.
and country not stated.

Mitsubishi tractor

Need to find the air leak, go back through and make sure everything is tight, check for damaged mating surfaces as well. Check the fuel filter and make sure they didn't double gasket it, by accidentally leaving the old filter gasket in place.

Transit pump code p0216 how can i fix this

P0216 DTC - Injection Timing Control Circuit Malfunction and this means the diesel fuel injection pump has a timing failure. This could be that the injection pump timing needs adjusted OR the failure is internal to the injection pump and therefore non-adjustable.

NOTE: If your vehicle is a Dodge Ram with Cummins engine then be aware that fuel delivery problems frequently cause this code. Prolonged fuel delivery problems can cause injection pump failure!

Symptoms of a P0216 DTC may include:
Low power
Crank, but no start
Hard start
Displays an intermittent stumble or miss
Engine may start and then stall
Engine may appear to drive fine but surge at idle

The most frequent cause of this code is a bad injection pump due to poor fuel delivery. Fuel delivery problems could be:
A plugged diesel fuel filter
An in-tank blockage
Air in the fuel due to a cracked in-tank fuel ine above the fuel level
Bad transfer (lift) pump
Injection pump out of time

Possible Solutions: First, simply check if your injection pump timing is adjustable. If so, check the timing and adjust if necessary.

If you think that you may have a fuel delivery problem, then check the lift pump operation. On Dodge Ram with the Cummins engine, the lift pump should produce about 45 oz of diesel in 25 seconds of operation. This can be performed by disconnecting the fuel hose from the injection pump and pumping the fuel into an approved container. Bump the engine over but do not start it. Then the lift pump will operate for 25 seconds. If the fuel is aerated, then check/repair fuel line and recheck.

With the fuel hose connected the fuel pressure should be 10psi. If the fuel delivery tests fail, replace the diesel fuel filter and recheck.

If it still fails then verify there are no restrictions in the fuel tank

Then replace the lift (transfer) pump. IT SHOULD BE NOTED that if this code surfaced after a routine fuel filter replacement or if you have any of the above symptoms after routine fuel filter replacement, then suspect the fuel transfer pump. This occurs because even a weak transfer pump can still provide enough fuel for the engine to run. But when the fuel system\'s prime is lost due to fuel filter replacement, it may not restart again without fixing the fuel delivery problem.

If you found your injection pump to be bad, the lift pump should be checked for operation to protect the new injection pump. This is because weak or low output from lift pump are common cause of injection pump failure. There are some aftermarket kits that can be purchased to warn the operator when the fuel pressure/volume drops to level that could damage the injection pump.

Hope this helps (remember to rating this free answer and leave a testimonial comments).

The cannister vent valve is bad. You overfilled the fuel tank, didn't you? Well, now you have to change it.. Here is the description of the circuit: This diagnostic procedure supports the following DTC:
DTC P0449 Evaporative Emission (EVAP) vent Solenoid Control Circuit
It is the round thing on the back of the gas tank, on the top side...
Don't overfill fuel injected vehicles with fuel any more. Fuel gets sucked into this valve and causes instant major damage.

Hard starting have changed fuel filter four times in two weeks

Either carry a lot of fuel filters or drain the fuel tank after it sits for a full two days, You have water in the fuelor a ton of algae. Confirm the water by pouring out the fuel filter. Any water will be obvious. The water in the tank will separate from the fuel if left standing. Then the water can be drained out the bottom of the tank.Water in the fuel can blow tips off injectors so take heed. and good luck.If you don't have a fuel water seperator, consider having a RACOR separater installed.

2001 mitsubishi galant,2.4L eng. Getting DTC 421. Is this code related to the catalytic converter? Check eng. light always on, also DTC 302 showing.

DTC code P0421 is the O2 sensor that indicates a an issue with the Catalytic Converter. Replace the O2 sensor to the Catalytic Converter "the one after Converter" It's common for the sensor to fail and you can pick one up from Auto Zone and they will have the step by step instructions to replacing the O2 sensor. 
DTC code P0302 Indicates a misfire on cylinder #2. Address the spark plug, spark plug wire, and injector. Look for any damages and try running some fuel injector cleaner through the fuel system to clean out the injectors. 
Good luck and hope this helps.

2003 dodge 5.9 diesel wont rev over 1500rpm

that code is a Fuel Delivery Error. Most possibly the water seperator needs to be changed.
