I've got a 2001 456mgt that has had a major service done with ferrari of alberta. At the time I also had all the valve guides done along with...
It should also be said that seating the efi corrugated fuel pressure line is absolutely horrible. I boiled the end in water for about 30 sec lubed...
Spa turbo. They are adjustable so you have to dial them in to the appropriate psi. 55psi is what it works out to with the bar conversion. Same...
Hopefully my winter long diagnostic journey can help someone in the future.
Alright. Appreciate all the help. I think I've fixed my problem. I replaced the high pressure fuel line and the wiring in the fuel pump assembly....
OK. Updates. I swapped the fuel pump assemblies before trying to diagnose possible fuel line breakdown. Low pressure followed fuel pump assembly....
Part of the fuel pump
More news. Just out of interest I swapped the ecu's to see if the problem follows and it didn't. Swapped fuel pressure regulators with known...
There is no way to put the filters on the wrong way. Is there anything besides the fuel pressure regulator that restricts the return lines fuel...
Yes I agree. One of the first things I did when I got the car was replace bad fuel pumps and the bad rubber parts and cleaned the tank. A low...
I'm not sure what to think now. I hot wired the passenger side fuel pump with a wire from the positive battery terminal with a switch and a fuse...
I actually had some time today to try to hot wire the pump. I wanted to bypass possible mouse chewed wiring before tearing into the interior. I...
So thanks to the document you guys connected me to I checked continuity through the questionable circuit board and it all checked out. Even the...
This is both super helpful And appears to be a potential form of torture. I will definately need to get my readers out. Was hoping to dive into...
I appreciate all your help. I got a second meter that is auto specific. It has plenty of amps range for reading dc but I felt like I was putting...
I clamped it on the hot wire while the vehicle was running. I turned it onto what I thought was dc volts and got nothing turned out into the other...
Not measuring amps. I started with volts and there is a variation. You can't read dc amps with a clamp meter. I decided to start at the volts and...
OK. I finally got to checking the main power line of both fuel pumps at the fuel pumps. The photo attached is the good side(0.016). The bad side...
Highest dc amp is 200mA not nearly enough. I'll look for one of those clamp style. It will be easier to check current at the pumps.
OK what do you make of this. I tested mA on the fuses of the left and right fuel pump. The left fuel pump at the fuse was getting me -0.159 The...
