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 1654
I forgot to add that first blink before the last 3
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 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
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.
The voltage readings came out normal on the sensor on the fuel rail. I don’t see a regulator on the injectors.
And there is no Shrader on the fuel rail assembly
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
