Sooooo just start having stalling problems with my 135 a couple days ago. Has 2800 hrs and I've never had any problems with it since I got it with around 2200 on it. It will run good for an hour or so then stall out flashing battery light and light right below it as well. Let it sit for a minute starts then stalls again. Also has long cranking as well after stalls. Will run fine again then stall just like prior. On and off like that all day. Checked all fluid and levels are fine. Battery has 12v and charges around 14.1-14.4. Not sure where to go from here. Possible wiring issue? Sensor? Hoping someone here has had a similar problem. Thanks all.
The first place to look is a plugged fuel filter, line, strainer, or pickup in the tank. Do you have a primer lever on the fuel pump? The battery light could be coming on as the engine slows down, unless the battery light flashes while the engine is still turning above idle, then look for wiring.
No primer. But I did change the fuel filter.
Could try teeing a pressure gauge into the fuel line between the filter and injection pump, and run the line to where you can see what happens as it stalls, and how soon the pressure comes back up if you crank it right away.
Sounds almost like a classic case of diesel bugs. If it is, these symptoms will persist and get worse as time goes on unless remedial steps are taken.
Remedial as in? So perhaps garbage in tank I assume. Also it seems to after it sits for like 10 mins it fires right up like usual.
Yes, garbage in the tank is one possibility, anything from leaves to "algae". Try the tee I mentioned, or crack the fuel suction line and listen for a hiss when it dies, or while cranking it immediately after. Or use a temporary tank to see if that eliminates the problem. Or try blowing air back through the line to the tank. A weak/dying injection pump solenoid (if you have one?) could cause your issue too, typically they'll go bad in the heat and work again when cool. Try leaving the key in the on position for 2-10 minutes after it dies, and see if that will keep it from "recovering".
what about the vent on the gas tank or in/on the cap ? if the vent is blocked then it could run or die like he describes.
Sorry, I'd already used up all my guesses.
checking electric fuel pump above battery might not be a bad idea, it does sound like a fuel delivery problem
Diesel bugs, better known as cyanobacteria, are very corrosive and can destroy a diesel engines fuel system, including the fuel injection pump and injectors. To mitigate the symptoms they cause it's necessary to drain and thoroughly clean and dry the fuel tank, fuel lines (including return lines), and all screens. Change all fuel filters and fill fuel tank with fresh fuel treated with a biocide. Continue biocide treatment for a minimum of three subsequent fuelings. I have personally witnessed this phenomena bring a 10,000 HP diesel to it's knees. This issue will become more prevalent in time due to the ULSD and bio-diesel fuels that are now being distributed. The old diesel fuel had lots of sulfur in it, something like over 500 ppm. The ULSD is much less, mandated by the EPA. So here lies the rub: the sulfur ingredient in the fuel abated the cyanobacteria. There are lots of fuel treatments that contain a biocide that are good for maintenance purposes, but an initial high strength dose is preferred. But before you jump through all those hoops, I would first test your fuel to see if that is actually your problem. I test my bulk fuel storage periodically using Hammond's Hum-Bug http://www.biobor.com/products/hum-bug-kit-fuel-additives/ but there are many others to choose from as well.
Interesting, I do run diesel kleen every tank but not sure about the previous owner. However today after a frustration filled day. I popped the hood to let it cool and noticed a sensor right after the air cleaner simply gone! Both wires broke off and it was laying beside the muffler. Not sure what it is but I ordered a new one from the dealer. Could that not working right cause the stalling problem.
Not having any idea what that sensor is but with plenty of new guesses... That's an air filter restriction sensor, and it has nothing to do with the stalling, unless the wires were shorting out???
That is the air filter restriction indicator switch. It's a normally open (NO) vacuum operated circuit, and when the filter gets plugged to the point of creating approximately 18" Hg vacuum then the switch closes and a warning light comes on. That was probably the other light you saw flashing under the battery charge indicator light. The only way that would have an effect on engine performance is if the circuit was driven by a PLC, and reduced your engine power, but that's not likely the case. I assume that you have checked the air filter. Interesting to note that Diesel Kleen (grey or white bottle?) does not contain a biocide. What you want in that product line is Bio Kleen http://www.powerservice.com/bk/ Another thing to note is that after the bugs are dead they form a black sludge (billions of tiny dead critters) in the tank and engine components and will actually pass through a 10µ filter quite easily. Remember, this is bacteria. The live bacteria is usually a dark brown. This is what most people unknowingly call algae, which is Latin for "seaweed", which it isn't at all related.
Took apart the water separator and it was full of boogers. Assuming algae. So I have rub 2 tanks of bio kleen and changed out the small inline filter. Runs a little better but I fear I need to get to the fuel pickup which I'm not sure where or how to get too???
It's not algae. Algae is Latin for seaweed. It's cyanobacteria, a living organism. If it's brownish color it's alive, if black it's dead. It can live on the walls of your fuel tank and propagate with every fueling unless you dose the fuel. You will have to thoroughly clean and dry the fuel tank, all lines - including the return line, and any filter heads, and change filters. You will have to subsequently dose three more fuelings with a biocide. The little critters can be very corrosive and do a lot of damage to fuel injection pumps and injectors.
While cleaning out the secondary and is a good idea and maybe the issue. Myself and my neighbor have both had issues with out TB153's dying. Both started it around 2k hours. Both were 07 models. It was a sensor issue, I cant remember the specifics but mine would die and after the computer reset it would run. My neighbor had that issue with inconjuction with another computer type issue which required about 4K to fix. I did not have that problem. Typically if its a plugged filter, the machine will exhibit other issues as well, such as low power, may overheat, cant maintain high rpm and so forth.
Just to clear up a little confusion, Cyanobacteria is the correct name for the algae known as "blue-green algae". It is the most common of the many species of algae growing in fresh and saltwater all over the world. Algae is definitely not seaweed, seaweed is any of the very many plants growing in saltwater. Algaes are unicellular organisms that have many, but not all the characteristics of plants. Cyanobacteria contains chlorophyll and requires sunlight to live. http://en.m.wikipedia.org/wiki/Cyanobacteria and you can find this from many other sources. The "algae" in diesel is commonly a fungus, sometimes a bacteria, and there is an algae that can live at the interface between fuel and the water in the bottom of the tank, though I think it is less common than the other two types of organisms. I heartily agree with everything else in your post, and can only add that I have had success with "Startron" fuel treatment. They claim that it kills whatever is growing in your fuel, and breaks it down so small that it will go through the injectors with no problem. All I really know about it is that it seems to take a lot less secondary cleaning of the fuel system when I've used it. Mitch
http://en.wikipedia.org/wiki/Algae The cyanobacteria requires no light to form and propagate as you suggest. There is usually no forms of any light within fuel storage tanks, let alone in the very deep settling tanks on a ship or on a tank farm. Anyway, as KSSS points out, it seems that perhaps the bugs are not the problem after all. It could be with the ECM.
I had the same problem ended up changing the little electric fuel pump top of the battery with a 7psi pump from Napa and no more stalling
i have a tbo35 that has 2900 hrs it does the same thing it runs good then just dies crank it back up dies again has overheating issues it has a lot of blowby and the engine seems to to be getting weak im gonna try the fuel pump and see if that gives anymore power
did cleaning out the fuel system cure the problem??
