Hello,
Does anyone know what the low side fuel pressure should be on the LNF Cobalt SS?
I had a customer texting me telling me that he got a Low Rail Pressure code right after doing a in tank fuel pump upgrade. He installed the AEM E85 compatible 320lph fuel pump.
He does have ZZP cam with upgraded fuel lobe and the Opel injectors.
But he states that he has not even got into boost since doing the in tank fuel pump upgrade and then got this code. So I asked him to check the low side fuel pressure, so waiting to hear back what he says it is. But I honestly never myself have checked fuel pressure on the low side of the LNF's to see what it even is.
Looking for key on engine off pressure readout.
Thank you,
