I got a 02 f250 7.3 with 56k miles. 2 weeks ago i started using b99 bio diesel. ran one tank and it ran good. thursday evening filled up again, ran it for about a hour and parked it for the night. friday morning-about low 50's turned on the truck and started fine.let it sit for about 5 minutes, put it in gear and stepped on the pedal and it capped at 1500 rpms. i turned the corner from my house and it wouldnt pass 1500 rpms so i parked it and let it sit for a couple of minutes and it idled anywhere from 1500 to 1000 to 750 and then turned off.Turned on and would idle at about 1250 and then dropped till it turned off.Did it about 4 times then it just would not turn on.It sounds like it doesnt get fuel.It is sitting at the stealership at the moment.Any input on possible problems would be greatly appreciated!
High idle is telling me the temps were cold enouph to engage the ebpv. Wont go above 1500 rpms is 1 of 3 things on our trucks, fuel pump, fuel filter and ebpv closed until truck is warmed up or malfunctioning. Let us know the outcome because I have run everything bad and good in my truck and can tell you I havent event clogged a filter even with bio or veggie.
well im happy to report it had nothing to do with biodiesel..of course there is a downside...took it to the stealership and $1500 later it was trouble code po1298 and replaced the injection module..I did check the fuel filter before i had it towed and it was in good shape. Well I hope this helps some for any future reference.
