      Hi Joey Both GTC4 & Daytona use a Marelli MT 21T starter motor (Ferrari p/n 100454) Regards Ian L

        Joe: if you are thinking of buying a Daytona starter, there may be other options. There are several threads on this forum about how to R&R the starter motor.

          Thanks! The starter seems to have a mind of it`s own, Will i turn or won`t` i, Every second attempt it seems to be sticking,i wondering would the best solution be to just replace it. Joe..

            Joe,
            have you checked the electrical part of the combined ignition/starter switch and the relay ?

              If you have other part of the electric system that are also erratic, you should also check the ground wire. Large wire from negative gorund on battery to frame.
              If the rest of the electrics are OK, then ground is probably OK, but the starter electrics are worth looking into.
              When the car doesn't start, do you hear any clicking of relays or solenoids or is just flat nothing?

                Hi jacques. I was getting a spinning noise from the starter,but no engagement, now i get a clicking noise when i turn the ignition,after a couple of attempts it starts, Not the most comfortable feeling when your heading out for a drive. Regards Joe..

                  Hello Joe
                  If you have checked all the connections to the motor especially the earth I suggest you have the motor overhauled by a specialist
                  I sent mine to G E Middletons in Manchester who replaced the solenoid & overhauled the motor. but I am sure that you can find someone
                  nearer to you
                  That was 5 years ago & I have no fears that the starter will work properly.
                  Regards
                  Ian L

                    Hi All. After checking everything i decided to replace the starter with a new one,(not installed yet!!) i got a aftermarket starter from the states(british starters), and i intend to get the current starter overhauled. Thanks for your help. Regards Joe.

                      I have a rebuilt starter, new battery, and there are times when i start the car after a drive, and it seems as if the battery does’t have enough power to power the starter. I keep the car on a battery tender 100% of the time. Start up from cold is spot on fire right up-Fully charged battery i suppose. I drive it for 30 minutes- sit in a restaurant, come out and i can get a couple of turns and if it does’t fire up- usually because i short change the fuel pumps- it feels like there isn’t enough battery power. If i wait for a minute and try again, i can carefully get it to fire up.
                      It’s a new battery, rebuild starter- is there a relay that boosts the voltage i need to look at?

                        Couple of things to look at. Make sure that initial timing is spot on.Too much advance especially on a hot engine cant make cranking tough.Check that cables are good and of the right size with clean connections. Heat soak can make the starter less efficient .You can wrap the starter with a insulating blanket or try the high torque mini starters.I have used one with great success. Finally check that the cooling system is up to snuff. Good luck,Mike

                          Hi Mike,
                          It’s not a starting issue, its a cranking issue. Meaning the engine starts up, hot or cold 2 seconds—Turn the key, counting 1 at the start of the key, 2 it fires- hot or cold no issues—



                          I’m losing crank power. Not really knowing the electrical, but know just enough to really not know—— if that make sense—
                          is there a relay (my limited knowledge) that boosts the voltage/power?

                            All the things I mentioned can either cause the starter to be less efficient or draw more current and effect cranking.It sounds as if you are in good tune as the car does start and runs well but initial timing that is too far advanced can cause harder cranking especially when hot and if the starter gets very hot it can seem "lazy". You have a solenoid on the starter that might also be an issue.There is no relay that boosts power but all the electrics get stressed when under more load. This occurs with heat induced higher resistance across circuits and connections. Was a new solenoid placed on the rebuilt starter? Please keep us informed . Best ,Mike

                              what specifically does the solenoid do? I’ll check my invoices as to if it was replaced.
