Eee gads--Poor old thing! What have you done to it!
No wonder 'WVO' has such a bad rep in USA! First I would do is get all that crap outta there and put it back as it should be! Then you'll be able to sensibly to diagnose the faults.... BTW--Those 'Orrible cheapo 'pre-filters' you've fitted are Nothing but trouble--Why bother using 'em. --Use the correct 'strainer' type pre-filters, the M.B. type--much better and dont have the moulding errors on the hose-barbs that allow air ingress--causing the mechanic to overtighten the hose-clips and allow even More air in! --The ones in the video are utter Rubbish!.

The last 100k miles on wvo with a heated two tank system in my 84 300d.It starts in cold weather,dosnt smoke and is driven every day.280k on the clock and I expect a lot more out of it with regular maintenance.Saving $1500 a year on fuel cost with a $1200 car is just so right.... |

just watched your YouTube video. from your walk through it sounds like you are not using the stock mechanical lift pump is that correct? the electric pump you're using looks like a Facet pump. those pumps I don't think generate sufficient pressure for the IP. What about your returns? how are you switching the return between diesel and WVO?

You know how the 716 and 717 manuals use the same clutch alignment tool as the Chevy S-10? Well, steamboat Willie and the OM617 Turbo used the same IP.

Why is it that the WVO junkies keep trying to come back into diesel discussion?
You were all given your own sub forum, look up at the top of the diesel discussion page !!! Best go back there. This is not a alt fuels forum. We dont need to go back to those days.

Without the lift pump in the circuit.There may be no reverse check valve to enable the primer pump to actually work. The reverse check valve is in the lift pump.

funola - the stock LP is still in use on the main tank that has the heating added to it. The returns come out of that switch and back into each respective fuel source, they are tucked underneath and I failed to show them
Tonight I put on a new electric pump and ran it straight from the small tank through a new filter into the IP. It felt a little closer to starting but my battery has gotten drained and I can't tell if it just doesn't have the juice or it's still a fuel issue. I'm retrieving my battery charger tomorrow and will charge the battery back up to try a startup. I'm trying to isolate if it's the LP or the IP. I figure if I can get it going on the electric pump it's probably the stock LP and if not it's probably the IP. It used to run great on this small tank and electric pump. I did find that the line was stopped up feeding it so that explains why it may have died.

can you post a drawing of ur fuel system diagram? if not how about a description of the routing of all components?

Not to be a jerk, but shouldn't this be in the AltFuels section?

andrewjtx - I don't want to step on anyone's toes here but I'm not really talking about alt fuels here. My vehicle does/did run some alt fuel but I'm currently looking for assistance in determining if my IP or LP is faulty. Just because I have altered the vehicle a bit does that disqualify me from asking questions here? Just asking that in a friendly way.
funola- The stock LP does not seem to be used when I'm on the "diesel" side with the electric pump. The mechanical pump pumps from the original tank which has had WVO in it as well as biodiesel. I'll try to make a diagram later today.

and accurately drawn diagram will help. the engine driven mechanical lift pump is pumping all the time and requires fuel flowing through it all the time for cooling & lubrication.

I watched your video and got dizzy. Some of these WVO setups look so complicated that I think the people putting them in could've spent the same amount of energy turning the WVO into BioD and then running it in an unmodified 123...

I guess it is something like this (primitive MS paint,sry) fuel setup. too many faulty equipment on diesel/electric/switch side for I suppose weak or dead LP. if I picked up setup correctly you dont second filter your diesel which is not good (even for that small quantities). as said before,loose the failing side,go with plastic bottle and LP+ IP only test. cheers ChO .

Here's the fuel diagram. I did this late in the dark so I hope I have everything correct. I spoke with the installer and he said the item with the ? is a bypass valve(solenoid). It allows the fuel(WVO) to loop around back to the tank while I'm warming up the engine on diesel.
Here's what I learned last night:

What kind of a switch is that with 6 ports? Since you are using the elec pump for diesel and the mech lift pump is out of the circuit and the car did run before, maybe something wrong with the switch? I'd try connecting the output of the elec pump direct to the IP input and run it from a gallon bottle of fuel. Rig up a clear return hose into the bottle so you can watch the return stream, which should be solid with no air bubbles. You say the primer pump is not pumping any fuel. But that's only used on the WVO side. Get it running on diesel first.
Don't recall if you are getting fuel to the injectors. Could also be bad injectors which can give you a no start.
