Your best bet is to buy a service manual from the dealer.
Yes if these are Mid 128 and if they are PSID 97 instead of PID 9797, They are fuel related.
Are the codes active or are they stored codes? I expect you have problems with the fuel control valve(FCV) or the harness that goes to it. If the fuel rail pressure release valve has been opened for any length of time you will need to replace that with the kit
Been a while, I thought 128-96 was low pressure side(lift pump up to fcv) and 128-97 was for high side (fcv, high psi pumps, injectors, rail etc) depending on the fmi
Injectors are "coded" they have trim codes. That said, it's for refined calibration, not getting it to run right.
As BW stated, the overflow valve has a very short lifetime. I think it can only be off seat for 200 seconds or so.
How does it run on start up? How long before it codes and defaults to1200 rpm? Worse when cold, hot?
As also brought up by BW measure return off cylinder head into measured container. Do not grab return fuel going back to tank from fcv, that's total return. You're only interested in off the head. That is what will tell you the injectors are shooting through and bleeding rail back to tank.
94-7 = feed pressure valid but below spec, are your filters clean and tight? Drive belt slipping?
Had a new belt drive pump last year,never thought to check tension on belt,will do now.
Filters clean and tight,what would cause 96-12?
