The light is on and blinks once when the key is turned on with the engine off.Is that light on? That is a MIL. In the olden days you jump to pins and count the blinks...some have it on the computer
Correction: The code is 1654how did you get that code?
if it is correct I'm gonna say injector #4
Correction: The code is 1654
I forgot to add that first blink before the last 3
Matt, this might help you.Correction: The code is 1654

Some people you just can't help.How come you never help ME?
new code after 1654was displayed 3times. code 91fook...654 would have made more sense
without something to cross reference 1654 might actually be displayed before the actual code or indicate that no codes are stored. Is there anything after 1654 blinks a few times?
again I'm not sure it is an actual code
Low voltage on the fuel pressure sensornew code after 1654was displayed 3times. code 91
Low voltage on the fuel pressure sensor
It’s the MAP sensor I replaced yesterday. It’s called a FPR in the manual but is a MAP at the auto parts store.if I had to guess at this point I would say fuel regulator is shot (go through the test procedures above). It is built into the rail right?
I looked around for a new rail and only found a crazy expensive one. Emailed PSI yesterday but haven't heard back.
if it is a built in regulator I think i'd find a a way to gut the regulator and add an inline one............or take a fuel rail extrusion and the injectors to a machinist
*there is also a standard rail for those but I haven't found a source....maybe Chicago Engines

Yeah it probably is, but it doesn’t apply to mine. I’m just gonna gamble on it and hope this ECU fixes it. It runs rough on the hot days anyway so I was thinking the ecu is damaged from where it was located for 2k hrs before I relocated it-
have you tried calling PSI
but that may be talking about the type where the FPR is on a tubing rail and not applicable here
like so
