removed HPFP and found the oil chamber was full of petrol. This confirmed the pump had failed could only offer the fuel rail low pressure fuel. One of the pistons springs had a small ring of metal that had broke away and was loose at the bottom of the bore. Removed it and cleaned all parts as...
My RCZ was running with an intermittent HPFP. It would reach 700psi and get me from a to b. However, it now only achieves 95psi. Now the engine runs poorly. I plan to remove it this Saturday and rebuild it after watching a YouTube clip on how to get them running again.
Yep my obd2 shows me fuel pump pressure. And when cold 90-100 psi then when engine runs ok at ideal it’s 700+\- then when driving at speed or acceleration it jumps to 1500+\- psi. Motors not running at its best as the timing is drifting beyond 30% at times. Yep timing chain in my thoughts.
Managed to start the Z. Had multiple faults. All cleared once I drove up the road. I’m of the opinion the trouble is coming from the BPGA unit. And in particular the battery module see pic.
Have found a $100au aftermarket unit from China. But can’t find the Delphi brand.
Update on Eco Mode Activated 2016 Z
after retracing and reinstalling the battery along with plenty of fiddling. I managed to start as normal. Ran it for a good hour parked in driveway. Stopped and started it to my relief. Went to the engine bay replaced all fuse and ecu covers and shut the...
I’m also have trouble with the same message showing up intermittently. My 2016 Z shut down completely for a week after i removed and reinstalled the battery. I tried every reset I could find on the net. Nothing just dash lights for 10sec and a message stating Eco Mode Active. 😒😬.
Ok thanks hoping to identify the HPFP model that is fitted to the 2016 RCZ 156tHP Petrol engine.
as the engine is manufactured by Prince engines. They are used in Mini Cooper S, Citrons and BMW. So I’d assume there will be someone in Australia supplying reconditioned units.
Have 2016 RCZ Coupe 1.6ltr petrol 156 THP 16v
this car mostly runs like a dream. However, recently it entered limp mode after almost stalling on a busy road.
I tracked the issue via Bluetooth ODI. Code p0087 fuel rail/system pressure too low.
I’ve been looking for the cars fuel filter...
