P0252 ... ... ??? cant find that in the stickey

Ive got a buddy broken down, he was on it and let out a little and it shut down. I currently dont know if he ran the fuel lines dry or not, but wrenches are on the way to him to crack them and see if the rigs getting fuel. . The codes are from the key trick no scanner. .

any input
thanks guys!
Ian


just called: they put a snap on scanner on it and it says fuel shut off is "off"

anything??

PO252= Inj. pump fuel metering control A range or performance problem (cam/rotor/injector) fuel valve signal missing.



Sounds like the VP44 took a dive.

Hmmm

The vp is maybe a year old too mechanical FP gauges reads 14 with a carter pump and lift pump... .



Thanks

Ian,



Might be wrong but it looks like the electrical part of the VP is having trouble. The inj. pump may be fine but the puter part is going. Thats what happened with mine, the pump was fine not the puter part. Although it could be in the ECM or the PCM.



Check all related fuses and relays, grounds and anything else.
