Starting problems the dreaded melted fuel pump connection

It's the lousy Ferrari connectors that started all this. As a temporary repair to get you home stay as far away as you can from the oem style. Find the right size female connector and you'll be on your way hopefully.

 

3/16 connectors will connect to the board. I found some at Radio Shack. I originally had the standard 1/4 inch as pictured. These connectors won't fit. I attempted to repair the two burned connections. Car started but would not start/run again after I shut off the ignition. Maybe my connections were poor. Car is now at Automotive International in Charlotte NC. I dropped by shop this morning before flying back to Austin. They had quite a few Ferraris.

I purchased the fuse box assembly from italiancars who recently posted the unit for sale. The new fuse box should resolve the problem. However, the white connector broke apart when I tried to cut area for the wires to pass through. I assume a new white connector can be purchased but will see.

In the near future, I may upgrade to the Scuderia Rampante. Or should I send him the new motherboard now? Or can Automotive International complete repair? Any suggestions?

 

The new circuit boards that are available are a very nicely made piece, I use them when I get a box in that has been modified, and then build up from there. I can deal with crispy boxes as long as they are virgin but attempted triage repairs induces variables that I am unable to predict.

Replacement of the box, (board) or terminals by themselves only deals with 1 or 2 of 8 known problems in the system. In this manner, fixing one problem simply moves the problems to the next weakest area. To resolve these issues in their entirety the box needs to be dealt with as a system, not a piece part.

Until all 8 of the design problems with this system are changed, the problems you seek to fix will just continue to be moved around in a game of chase.... a terribly frustrating one at that because the symthoms morph with each triage change made.

 

I would do it now. But then, I already did and am very happy for it.

Very Happy with it.
Chris - I would recommend it highly - Dave will go through your box and once back all those electrical bug-a-boos are gone. Not sure if you saw mine at Mondipalooza - I had the front boor open a couple of times to show it to others.

 

Where did you order the white block and the connectors from?

Thanks,

 

There is a better fusebox concept on the market and cheaper :

Looks more like OEM and no wiring or relays hanging around.

This is another great DIY guide!! Thanks.

Hot start of my 3.2 needed at least 2 cranks to fire the engine. Sometime up to 5 cranks.. I just bypassed the fused connector pin with direct wire+solder & replaced fuel filter. Hot start is better but still not up to my expectation. Now most of the time I need just 1 crank for 3-5sec & press on the gas pedal to start the engine. Is this good enough? Thanks.

 

Dave,
Am I being ignorant to think these fuse box gremlins were "fixed" by Ferrari on the 3.2, 328 and later Mondial t's and 348's or is that just wishful thinking?

 

Peter I'm a little late but happy birthday from Canada as well.

 

Hi all, Other than the melted/bad connection in the vertical large white connector on the right side of the fusebox, I noticed there's one more connection that's melted in one of the four horizontal white connectors. It’s located in the bottom left white 12pin-connector, 3rd pin from right is bad. Any idea what’s that connection? Thanks.
