Fuel injection issues? Possibly run carbs? Options

[ndfrigi]

Ok it’s bad trigger points the thingy under the distributor that has gone bad. If I can’t find those where do I find the distributor that works to stay fuel injected?

nice! good you can keep the F.I.

You've gotten a lot of advice and info here, I'm not going to go over any of it again. If you decide to keep your D-Jetronic FI system, you can find a lot of information about it from my web page:

http://members.rennlist.com/pbanders

Note that I haven't been able to gain access for several years to update these pages (can't get anyone at rennlist.com to respond to my requests), so parts that I list as available may no longer be available except from eBay or classifieds. But you can still learn how the system works, and how to debug most problems. Good luck.

Agree, 123ignition. One of the best things I have done for the car. Just put your old dizzy on the shelf for the next owner if they want it.

Yes, the D-Jet version of 123 provides the functionality served by stock trigger points. Works like a champ.

[emerygt350]

Yep, just put the two leads from the distributor into the pigtail that hooks to your old trigger points. No cutting or anything. No harm and you can always put the old one back on if some fool wants it original.

I have one of these for my 1.8. Can I buy and run a djet system on my 1.8?

You don't need trigger points on a 1.8. L-Jet doesn't use them. Just get the proper distributor for a 1.8 and plug it in.

I have the single carb on the engine. Snce I have the distributor , can I buy the djet setup and use it?

[nditiz1]

No

The one you have is most likely for one with carbs. It possibly has the port for svda. I'm not sure if 123 has a dvda one. Regardless, if you wanted to go back to FI you should get all the Ljet stuff, not try to throw djet onto it which WILL require a different distro.

[pbanders]

FWIW, I just found four sets of used trigger contact points on ebay ranging in price from about $25 to $75. A new 123 dizzy with single port vacuum is about $500.

[emerygt350]

And worth every penny.... I can always go back to points and triggers but for daily driving/racing 123 is great.

[ClayPerrine]

My suggestion is to float test the single carb. Throw it in a lake. If it floats, use it on your car.


Now for some real advice... find a complete L-Jet system and put it back on the car. You will be much happier than the single pinto/weber carb in both performance and mileage.

When I looked at the 123 distributor it looked like it plugs into the trigger points and keeps them? I’ve seen trigGer points on eBay for about $50 but I like what I see in the 123 especially if I do not need trigger points that could wear out again. How does the distributor fire the FI without the trigger points? Is there a seller of the 321 I can call with questions? I’d like to buy this ASAP if it lets me keep my d jet FI and not run trigger points.

[BeatNavy]

No, you don't keep the trigger points. The trigger points are integrated into the stock dizzy. They're gone when you swap it out for the 123. The 123 has two electrical leads that plug right into the FI wiring harness which was previously inserted into the trigger point connector (on the back of the old dizzy).

I've got the older D-Jet version (non-Bluetooth). It's actually installed on an engine sitting on the floor of my garage if you want a picture or something.

The sales rep for 123 has, or had, an account here. Can't remember it though.

The 123 distributor does not have physical trigger points. It has an electronic emulator for the trigger points. So you don't need them with a 123 distributor.

Hope that helps.

That carburetor (or any single) fitted to these engines is a quick way to experience the worst ownership experience possible.
People go to these because they *appear* to be simpler and easier to tune than duals.. This could not be further from the truth. These carbs are damn near impossible to tune, primarily due to the long runners that allow the fuel to form droplets and enter the chambers as liquid that has fallen from suspension and lost atomization characteristics.
This means the engine always performs and tunes like it is rich, even when it is lean.
I rip them off, and crush them with my bulldozer, or tracked armored personnel carrier.
