awake to new life - Ferrari 400i afetr 20 years

Andy:

Congratulations on your new acquisition and best wishes for many happy miles when you get her fully awakened for the road!

I'll let the other, more knowledgeable, technical experts here help you out with the fuel pump issues. You seem to have confirmed that the fuse and relay panel is working correctly and that is important because those connections are a notorious weak area of the car.

Best,

John

 

Schönes Auto! Tolle Farbe!

Can't help with the ignition, but a thourough cleaning of all part, new fuel lines and some gaskets/filters will do wonders.

Please post more pictures! I love (semi)barnfinds.

I can't help either, but welcome to 400 ownership and FChat.

welcome. i found that my DeLorean had the same fuel system X 2. the Alpine 310A the same. parts were very cheap when the box did not say Ferrari. you need a PowerProbe to track down lack of function. plodding and painfully slow analyses, but doable

Your car is a nice color for a 400.

I had similar fuel pump problems. First the left side pump would not run when starting up but would kick in after a few minutes. Then it started dropping out on long trips. I first replaced the pump. Later I found that the terminals were burned. They are located in the right hand plug (8 or 10 prong white plug). I bet if you pull the plug you will find bad burned contacts and plastic. I replace: white plug, connectors for both pumps, relays for both pumps. Left pump worked fine; now the right pump started acting up in spite of all new things in the relay/fuse panel. One poster claimed that old pumps draw more current leading to the overheating of components. I now agree with him. I replace the RH pump and have had no further problems.

Since you replace one pump already I suggest you replace the other plus both filters since you are having injection issues too. Check the connector for overheated contacts. Both the plugs and connectors are available from F-dealers. Replace the two relays with the new plastic cap type.

I hope this helps with the pumps.

Great find!

Don't forget the tires are 20 years old also. You might want to replace them before going on a high speed run.

 

switch on, fuel pumps will come on.

The pumps are not supposed to start until there is air flow through the left side Fuel Injection system. There is a little plug in switch in the body of the Bosch distributor that detects the disc has risen off its seat. If you pull out that plug (I have done this 100 times while testing) the pumps will start with the ignition switch. There is a fuel accumulator after the pumps to give you plenty of fuel to get motor started, unless it has sat for months. If you look at Right FI system there is no plug which is normal.

I have not yet looked at your pics. If I see anything interesting I will send a second note.

The second picture shows the connector with the fuel pumps. One of the pumps has brown wires and is near the top of the connector. I forget the second pumps color.

When I pulled my connector out the side of the plastic was "crispy" brown. Yours looks okay. The terminals also get weak over time but if they are not making good contact they will arc and show the heat.

The replacement pumps I bought are about 25mm longer than the original pumps, so you have to cut the fuel line from the tank a bit short. Also check that the pump is not hitting the chassis if you end up with same pumps that I have.

Wow!!! Those leather seats look to be in near-new condition!!!

 

Do I spy a yellow Daytona in the garage as well? Nice find on the 400! Wonderful road car!

Talking about hidden treasures And that Daytona maybe out of our budgets, but remember, now you own the sophisticated 4 seater version of the Daytona

 

Man I just love these barn find stories.

 

It really does make me sad inside to see these cars just parked and essentially forgotten about. If you really can't drive them then there should be a rule that says you have to sell them to someone who can take care of it.

I am so happy that both the 400 and the Daytona are going to be driven now!

 

Many congratulations. What a wonderful story.

 

me too

 

Is the 400 marrone? I love that color
