Jeff, they found the three lean cylinders via a lean reading in three of the individual "test tubes" built into the headers. Once they swapped the injectors around the lean condition moved to the other cylinder thus pointing to a faulty injector. They then bench tested the injectors to confirm . Once they replaced the bad injectors the cylinders then tested fine...problem solved. |

Mine run very rich on all six cylinders on the side of the FD that has been rebuilt seems like it stays open a bit too much (stuck?) having to get it rebuilt again, I think |

This is a very interesting thread. I recently bought a book on Bosch fuel systems and have been trying to understand this constant injections system our cars use. It would be very unusual for a few cylinders to be lean and not all of them on one side. As I was reading the start of this thread I was skeptical of the injectors even though the shop said they were okay. What did they do differently to finally point the finger at the injectors? How did they determine which cylinders were lean, using heat measurements? Looking at the spark plugs? I would like to learn more on this if possible. |

I have indeed had mine rebuilt by a gentleman in Louisiana by the name of Larry Fletcher. I did not rebuild both...just the one that was jammed..the jury is still out, within a day or two, it may have to be sent back for another rebuild. I would say, a rebuilt one is much cheaper...T Rutland quoted me 700-800 for the exchange for a rebuilt one, and some 1800 or so for a new one. I doubt he has a new one. I don't think they are hard to rebuild, but require lots of care. So I can't recommend the rebuild, but neither do I think that a new one always solvesd the problem. Frank, give me a call..I will elaborate..or a private email |

Well it turned out to be three bad injectors rather than the fuel distributor. I guess I dodged the bullet on that. But, they did find a sticking rear caliper that needs rebuilding at a cost of $300.00 and it will take 3 to 4 weeks to get it back. Old cars and women, I don't know which cost the most to maintain ! |

Frank - I have excruciatingly painful experience. My fuel distributor, pressure regulator, and pumps all had to be changed. We sent the distributor and regulator to Bosch to rebuild, and after 3 attempts and many hours of labor (read cost), they did not get it right. I finally purchased new distributors and regulators and pumps. My recognized expert mechanic warned that it was extremely difficult to get these calibrated correctly, even by Bosch, and he proved to be right. My suggestion is to start with new devices out of the box and save the labor and hassle of several iterations.

I have heard that about WURs but not FDs. I wouldn't pay $1500 for new one maybe more for a BBI. It is just a diaphram and a plunger. I haven't had one rebuild but I have had many friends get theirs rebuilt without any problems from this company. I would say it depends on the rebuild shop. I do think I remember a guy on here where he had his rebuilt by a local or the like and it didn't go well. Anyway just MHO. |

I have been under the impression for many years that rebuilding a fuel distributor was not a very good idea. A rebuild is extremely difficult. I may be wrong but I think I would try to buy a new one.
Another thing you may want to try first is to take the car down to a good shop and have them flush the FI system. I have seen set-ups that are made to attach to the injection system and shoot a highly concentrated detergent thru it. You may find that this may do the trick. |

I looked on the www.owners.ferrari.com parts section and couldn't find it either. |

Yea Dave, I thought it sounded screwy but couldn't pick it out from the Ferrari UK parts site. Probably operator (me) error.

Fuel Injection warehouse rebuilds them for about $300-$400. This was a year or so ago though. |

Drew, "fuel distributor" not "fuel regulator"....the distributor is probably 3 or 4 times that amount (guessing). |

I believe Coach I M Ibrahim sent his out for repair on his 512BBi about a few months ago. Maybe he could comment or you could contact him.
The Ferrari UK site has a fuel regulator listed at 139 pounds but you may want to take a look and make sure I've look at the right part. Sounds very inexpensive to be right.
Regards,

While in the shop to have a torn CV boot replaced, FOA discovered that I had three cylinders on one side running too lean. They said the injectors all test fine and believe it is a problem with the fuel distributor on that side. Has anyone else every had that problem ? If so, how much did it cost to have a fuel distributor replaced ? I am waiting for an estimate on the repair. |
