Hey folks, I've had a buddies old 914 stored at my place for years, and I recently sold my project truck, so, being between tinkering projects, I thought for sh*ts and giggles I'd see if I could get it running again.

fwiw, it's a 74 2.0 le bumblebee, tho that makes it sound a lot better than it is. kinda rusty, dubious wiring and even more dubious engine.

Used to be into vw's back in the day, but always had carbs. And I'm not having much luck at getting the forums search engine to look for info for me.

D-jet and the like don't jive with the search commands....

So, any good threads to read up on for info on troubleshooting the system, or a good manual?

I usually mess with diesel landcruisers, and the FSM was available to download in pdf form, which was great, anything like that here?


thanks,
ryan

Google Paul Anders. He has a web site with the most D-jet info that is easy to understand. Brad's '70 914 2.0L

I saw a bosch d-jet book on ebay, it covered the d-jet on all cars that it was used on I think.

You will also find several free downloadable D-jet manuals here:

http://bowlsby.net/914/Classic/TechNotebook.htm

Also, about your Bumblebee, would you mind telling us the VIN for the 914 LE registry? Sounds like this car is not on it yet. I can put you in contact with 2-3 other 914 LE Bumblebee owbners in your area if you like. Here is the 914 LE website:

Thanks for the links guys, we'll see, at a wild guess I'd estimate this thing will need a new harness and a bunch of fi parts to run so I'm not sure how much time I'll spend messing with it.

I'd be the type more inclined to throw some carbs on it, but thought I'd poke around and see the state of things first.

theres also a running 73 for 1500 bucks not far away, these things tempt me sometimes... screwy.gif




Part of the issue with this car is that it's not actually mine, belongs to a buddy( I remember ripping around Nanaimo in this thing around 1990 when we were in highschool) I doubt he'll ever do anything with it, so I'm going to talk him into signing it over to me. If he doesn't want to then, I'll just stash behind the barn again.

And Jeff, I did ad the vin, chassis ,colour code and build date to the registry. I probably added it a few years ago when I'd first thought of messing with the car, but then moved, and got into other projects.

I'm pretty sure it's an le bb, ( definately black and yellow under the red )

Look for seapotato, and you should find it. I once logged in here as derelict74, and somehow managed to log in twice, so I deleted the one, and stuck with this user name, as I tend to remember it...

cheers,

Ok, I'll write a little bit more. Djet is really simple, wiring issues are usually the problem so a new harness fixes alot of issues. MPS thats working is a must! Lots of them around used plus lots of junkey rebuilts of varying quality. Good TPS, trigger points in the dizzy are easy fixes and the ECU's rarely fail unless its rusted out of you hook the battery up to it to see if it sparks.
All the Djet parts for a given year must match up number wise as they upgraded it nearly everyear. 1.7 and 2.0L stuff doesn't match up too well.
Get the injectors cleaned and tested before you run em. Change out all the fuel lines and injector hose to new high grade high pressure FI hose. I like the Porsche stuff, it lasts and doesn't harden and crack on you fast. Use the same style full circle fuel line clamps too as the carbs screw type chew into the hose causes leaks which causes fires.
I put FI back on my 76 in 1998 ditching the dual carbs without much help and figured it out by looking at another 914 and took pics. Started right up first time and is still running strong!

I've heard feedback that the 2 Bosch FI books available from AutoAtlanta, Performance Products/Automotion, Pelican, etc. are good overviews, but may be light on details. However, they're not bad to have on hand in addition the the website lined above, which is really good & directed to 914s.

Even if rust, if you can confirm that it's a real LE Bumblebee (i.e.: via a COA from PCNA or if it's on the registry at the link below), then it's well worth restoring it to original with the D-jet & fixing all the rust properly, since they only made 1000 or so of them - period, which is less than the 3000+ 914-6's.

Look here & read up, & Jeff is great for answering questions on his LE passion, as well as supplying rebuilt/restored engine EFI & other electrical harnesses -

http://bowlsby.net/914/WiringHarnesses/ - this also has wiring diagrams to download

This is also a good site for 914 info & correct parts per model & MY -

Also try JRust on here who is up there in your area, as he's doing a Cremescicle resto & selling another confirmed Bumblebee, so he knows the PNW parts sources & Teeners.

Keep us posted on your progress!

Thanks for all the links guys,

small update, I vaccuumed 40 pounds of pine needles out of it...



Anyways, had a visit with the buddy on the weekend, it's semi officially mine now, I think we exchanged a beer as payment, (perhaps more than one...was a long night.... beer3.gif )with the provision that if I ever sell it, he gets dibs and a discount which works for me.


general state of rust is that the floor pans are good, inside bits of the longs are good, outside bits, not so much....left side it's jus a small section around the jack point, other side is fairly pooched as always. Not too worried about that, it's just a hunk of metal.. welder.gif


But before I mess with rust, I'm going to check into the state of the engine. Picking up a battery today to see what happens , how many things will come back to life.


Just for argument, how terribly unsuited are a set of weber 34 ict's for a 2.0?

I've read 40's are the preferred setup, but there's a set of the 34's for sale super cheap not far from me, struck me as a quick way to get things moving, even if they aren't ideal.


(This is me thinking that the fi is going to require too many parts to bring back to life...)

If they're awful and waaaay too freakin small, I won't bother.

cheers,

I find the 34's too small but some don't mind em.
I would just try to get the djet running..change out the fuel lines and clean out the gas tank. pull the injectors and flush out the fuel lines from the tank into a gas can.
then try the pump to see if you have pressure.
see if you have spark,
then try to fire it up.
be ready it could catch on fire or just run fine.
