so i just put in a 2 tank system, testing it out. bled my fuel lines had diesel in both tanks. once that started working i put in used veggie oil in the 2nd tank with the diesel already in there. i then got the car heated up, fuel and all was hot. when i was driving and switched to the 2nd tank with veggie and diesel. it would shortly lose power, then i would flip it back to diesel and it would clear up. i thought it may not be hot enough so i drove more, and switched to veggie, and lost power again. wasnt able to switch back in time and the engine turned off. Now i cannot start the car. i switched back to the diesel line, vaccum sucked stuff out of injector pump, and re bled diesel into the line, and hear diesel going into injector.
still will Not start. please help.

why would i lose power?
How to start trying to start my car? how to check to see if fuel is going from injection pump to engine?

i think it may be something with the diesel veggie mix and clogged my Injectors or the pump. maybe replace injectors, check injector lines for cloggage.

VO conversion - engine failure

Suppose you were an idiot. And suppose you were a member of Congress. But I repeat myself.
- Mark Twain, a Biography

I wish all of the veg oil wannabees would read this before they go destroying good cars with their ignorant overenthusiasm. Someday there won't be any decent MB diesels out there because the idiot WVO crowd killed them all using animal fats/hydrogenated oil/poorly filtered oil. I'm not talking about you MattSD300 or you RLeo, since you obviously know what you're doing and respect your vehicles, but the rest out there don't know jack and think they can 'just do it' without doing the research and taking the proper precautions.

WVO is SIMPLE!!! But YOU MUST follow the RULES!!

it ain't rocket science, but apparently too complicated for most out there

Is the oil filtered? Are you running 2 fuel filters...one for D and one for O?
Did you switch you pump to pull from push? Are you using 3 port or 6 port? How are your return lines setup?

I take some offense to this statement. I've been running on WVO for more than half a year now and have racked up about 5K miles so far. I've had a few glitches along the way but they were mainly fuel delivery in nature. I tripple filter my WVO so the oil so it doesn't get any better than that. Its a very time consuming process. My car runs great as it should. It hasn't lost any power at all.

you didn't describe your system very well, but there are a couple common problems people run into when first switching to wvo...

if your system has a looped return (in other words, no line to return fuel back to the vegetable oil tank) you could have air trapped in your lines... this is probably why you could switch to diesel and keep the car from running roughly (the diesel fuel system, as per stock, has a full return line and purges air better than the looped vegetable oil system)
check all your connections and make sure they seal tightly... then purge any air from your lines

also, check your filters to make sure they are clean and unrestricted...

i'm not sure why your car won't start...
make sure your battery is not discharged from too much cranking, and remember to give your starter a chance to cool off when cranking so you don't burn it out...

since you didn't seem to wait a long time to try and restart, the vegetable oil in the lines still should've been hot enough to flow through everything and start again (that is, if your system gets the oil hot enough)...

if you think the oil in the lines and ip is cold and hardened, try heating it up with a portable heater indoors or by pouring boiling water over evryting...

to check that you are getting fuel to all the injectors, crack each line a little and watch for fuel leaking out while cranking

ps.: it is not a great idea to run diesel through your hot wvo system as diesel loses its lubricating properties rapidly when heated... this shouldn't cause damage in the short term though...

All apologies, but I'm standing my ground on this. You can't just throw some oil into your tank and expect everything to be kosher. And, since you are triple filtering and the car runs great, apparently you are doing things correctly and aren't using the wrong stuff. Others out there aren't. They are ruining the cars' injection pumps, thereby for all intents and purposes ruining the cars themselves.
The fact of the matter is silly individuals who can't tie their own shoes are getting their hands on these cars and in their haste to jump on the hipcool bandwagon they are killing them. These are the same types of people who don't have a clue that diesels don't use spark plugs and advertize that their car gets 'great gas mileage' and 'is known to go a million miles' after they've had their fun novelty moment and the car dies on them.
I'll run petro or B20 until B100 becomes widely available, until such time my car will be worth more since I haven't molested it to run on fryer oil. No rust, no jerry-rig WVO crap, all systems go.

Think about us (who have molested our cars w/ vo and "wvo crap" ) when you are paying 40 to 50 dollars at the pump.

Delano, if you don't want to run it, don't and we don't care. All I know is that I jumped in with both feet and ran as much old grease through that old Mercedes as I could this summer, (from mid May to mid October) Did get a little water in the fuel once in June, drained it out and saw my error and put new "old grease" back in. Now it is a bit too cool, but I can't wait until mid April and I will be at it again. Doing it the hard way, home made filters and all, no pumps, either I pour or syphon that nasty old engine killin grease. But I can say the ride was really great on that old grease, and the car really smelled and sounded good, and ran totally perfect. Now its back on dino with 2% bio, and it still runs wonderful. If it shows up in the life of the IP, hey I have that covered also. I have one under the bench in the garage and I see them for sale on Ebay quite often, usually for less then 2 tanks of fuel. I plan, the Lord willing, to go four wheeling in Colorado next summer and plan to make the whole trip on pure "old greasy grease", using my standard fornula of 5 gallons grease and one quart of regular gas, pulling my 4x4 Honda 350 and enough fuel for 2500 miles on the trailer.

I already do. Then I think about the caveats(which are myriad, time, effort, risk,etc) and come to my conclusion, which is completely rational. I never considered it a bad idea, nor do I enjoy reading about the oil co's record profits. Sustainability is a big concern of mine. That's why my bike racks up most of the miles.
My point is don't be reckless about it, which is why I posted a link to Matt SD300's thread about common sense when using WVO. All of you who are offended just chill. Just two schools of thought that's all.

That's all it is, common sense. Some folks have less money and time invested in their diesel, so it's easier to justify a higher risk fuel. Personally, I drive mine every day, so I make the best biodiesel I can, and cut it with antigels for the colder months. I will not put vegetable oil in my tank for any reason (thinned or heated), I need the reliability a clean-burning fuel offers.

Delano, I don't get why it matters to you what people do with their cars. None of your business. Besides, if they kill them, yours will just be worth that much more.

Folks get to make mistakes. We all do and end up paying the stupid tax.

what where the conditions of Mike not being able to start did yours no longer start after dieing when you switched to wvo. mine did and now i cant get it started. and couldnt get it started while engine was still hot from running.
trying to figure out what the problem is, or how to just get it running off of my diesel tank.

I saw BHANSONS post i think may try that, check my lines. i have one question though as how to check for blocked lines. do i disconnect the return line and try to start the car and see if anything comes out?

TonyFrom... thinks i have air in my veggie side, this may be very true. but i was able to get it up and running on diesel before if konked out. so its on my diesel line and that side seems fine. would that effect me being able to restart my car.



i let my oil settle in a 55 gallon drum, i hot filter through a bag filter.
in my car i run 2 fuel filters one veggie and one oil.

Switch pump to pull from push? where is this, what is this?

6 port valve. my return lines are set up like the frybrid set up i found in a forum. replacing the banjo. re-plumbing it all that way. so it in a semi- looped return .
frybrid diagram link http://www.frybrid.com/forum/showthread.php?t=3

im kinda wondering where to begin? my diesel side was operatable, i cant get my car started now i figure i should be able to. i just want to get it to run again. my battery is probably getting low. do i need to trickle charge it all the way up, or can i jump it off of a running car. i know ill probably have to warm the engine up some somehow before i try to crank it. do block heaters get hot enough.

as for being a wannabe.i am one. it just means that Yall who know it all are leading the way and its amazing. no one famous in the world became famous sitting idly by and letting the professionals be professional, they took risks exploring all possible things, it all starts somewhere. ive been researching for about 9-12 months, while waiting to find a deal on a car. if it goes to pieces then it goes to pieces, ill replace the engine, or you guys can have my parts. Life is a thing of adventure, and risk, if you never mess anything up you may be playing it too safe.

I back you up. It seems quite a few people think you can just throw any fuel in there without thinking it thru. I had one person believe they would buy my '80 wagon and set up a few restaurants on her regular road trips to have oil ready to pour in the tank....

My response is.........so what?

People can do what they want. Many times people do things that can best be described as moronic. Who would purchase a vehicle that weighs 6000 lb. and gets 12 mpg for the sole purpose of commuting to and from work?

But, people do it every day.

Provided that it does not affect you in a negative way............there's no need to get excited about it.

Either help the folks who are clueless.........or watch from the sidelines.
