So the F1 fluid leaked down to cause the engine and F1 error icons to light up. I added fluid to correct level. I try to start the car, F1 pump is working, foot on brake, pull on levers and I hear the clunk to N, then turn key to start and engine starts but then stops after about 1 second. Wait a few seconds and try again, same result. Any ideas? Do I need to get the errors read by SD machine before I go further? thanks
I am assuming that everything was working fine before level dropped ?? Sent from my moto x4 using Tapatalk
actually the left rear is jacked up so I can watch fluid leak, but car is still in N, and I get the check okay at the start will air in F1 system cause engine to act like that
If the car rolls means it in neutral and I don't see how the gearbox would have anything to do with the stalling. Massive air leaks yes, sudden electrical loss yes, fuel delivery problem yes. So for starters doing simple things. Once started see if you can run the car on starter fluid. A fail there implies fuel delivery issue or partial electrical failure.
I am wondering if there is fail safe system that if the clutch or or gearbox or diff is not getting the right pressure that it shut car down The only reason I am thinking this is if car was running fine before leak of fluid I have to defer to someone who would know the ecu/tcu safeguards etc Sent from my moto x4 using Tapatalk
earlier this month i was tracking down what i believed to be a voltage leak, which I think was a wild goose chase. But i cracked the top of the secondary air relay when I pulled on it as part of tracing wires. I do not know where a small piece of the cover went. If it went into the relay and stopped the relay from functioning, could that be a cause? I have a new one on order.
I do not think so. Car will run fine without secondary air. Besides you can pull a relay with same number and plug it into that spot and prove it. Any relay with this layout should work so hit the autoparts store if your relay shows the diagram or you can google the number you pulled out. This one pictured is the 550 layout. e Image Unavailable, Please Login
Just for the record .. checked the advance electronics manual on a Maserati which has the similar f1 components and confirmed that they are situations when there is a low pressure , very low fluid etc can cause instant engine shutoff. I am not saying that is the issue here but it does appear that there may be some safety measures that shut down the engine based on what may be going on with fluid pressure or level ... At least in a Maserati f1 ..FWIW Sent from my moto x4 using Tapatalk
I am going away for a cancer walk this weekend and will be back next week. I will proceed on monday. thanks for responses.
There is a tilt sensor/shut-off valve that may be causing your problem if she is jacked up on one side. Shuts off the fuel flow in case she rolls on you or goes off the road at a steep angle.
On my 550 if I jack it up with the battery connected the alarm activates, learned that the fun way Surprised you can jack up a 575 without this occurring, since you are trying to start the car I assume your battery is still connected? As mentioned, get it to level ground and see if it starts. If not, it may have something to do with the immobilizer or that shut off valve, I believe they stick at times Do a search, believe it has occurred to another member on the 550/575 forum if my memory serves me correct...
I have heard of cars not starting when significantly oddly raised. I know I have run my 550 on a jack doing a corner brake bleed at a racetrack.
back on level ground and no change. I suspect this all started when the F1 fluid was very low and gave me the F1 low fluid notice. Now the F1 icon and engine is lit all the time. Engine tries to start and is then shut off after 1 sec I will likely send to dealer.
It is going to take an SD2 or equivalent to get rid of the F1 lamp, at any rate, and it will set off the CEL when it comes on.
I did read that this sensor / valve sticks at times, do a search and see what pops up. here is the ricambi information diagram not certain it is near the siren or the battery... A few years since I read, someone took one apart https://www.ricambiamerica.com/car-diagrams/ferrari/v12/gt-group-2-seat/550-maranello/anti-theft-electrical-boards-and-devices.html
That sensor is behind dash, driver side on 575. MIght be reachable, but WSM says to remove dashboard. Image Unavailable, Please Login
okay, it was my error. When I was tracking down what I thought was a electrical short, I evidently left the connector to the F1 ECU slightly unconnected, not firmly seated. Starts right up. Now tech is trying to discover why I lost so much F1 fluid.
