I have 2007 CX-7 2.3, but same engine... The OCV valve is not working. The valve itself tests OK as does a spare I have. If you run 12v to it, it opens correctly. The constant 12V is there at one terminal but I appear to be getting no ground signal from the ECU. I have measured the resistance in...

Hi, All good! I cleaned/rebuilt the HPFP with new Viton o-rings and it is working fine. BTW I found in a Corksport pdf for the rebuild that you don't need to release retainers for a stock rebuild. The piston will go back in the same way it came out. I just used a bit of clean engine oil on the...

Hi, thanks again for the input. I had a look at the Autotech instructions (I was following the Corksport info). The Autotech instructions shows the piston parts as they came out of my pump. So, it seems that you have to remove the spring retainer keepers and put that end of the piston through...

Also forgot to mention that Forscan gives a P0172 code and the CEL is on (which was not the case before the VVT failure). The car has been sitting in the garage for two years...too many projects. It had VVT failure and bent valves. Finally got all that fixed and recon the head. I pumped out as...

Also when I pulled the pump apart, the shaft with the collett attached came out. Can I reassemble it the way it came out or does the collett need to be removed from the shaft as shown in Johnny Tight Lips post?

OK thanks for the replies. I only have Forscan with an ELM327 USB interface. It reports zero psi in the HP fuel rail...but the car starts and runs ok at idle, but barely drives as I assume it is starved of fuel. If you disconnect the low pressure pipe to the HPFP gas is being pumped OK, at least...

If I just clean and replace the o-rings and not replace internal parts, should this be enough to fix a low rail pressure?

I have 2007 CX7, but this forum is more active. I have low rail pressure and I think the HPFP may be the problem. If I rebuild/clean it just with an o ring kit and not new internals, should this be OK for a road car that has no engine mods?
