Good evening, I have been trying to fixed this truck for the passed three weeks I got in to a point I don't know what else to do . The truck had stop at a red light while the owner of the truck was driving a technician replaced the fuel pump and also one of the camshaft sensor nothing good happened . Once you start the truck it will crank and start as soon as I pressed the gas pedal it's shut off. I scanned the truck these are the codes p0010ff , p0020_ff , p0443_ff , p0446_ff , p1000_ff , p0461, p0191,p0155 p0135 , p0113 , p0102 . Every time I deleted the codes they came right back . I am thinking about replacing the PCM I need some help of what else it could be please help thanks

This list of codes is not helpful. You may get more help if you include the code definitions so people can get an idea of what's going on with the truck without having to leave the forum to look up each individual code.

I agree with Noah, define the codes. Secondly don't replace the PCM, you will make things more difficult to help you here if you do. With service info and diagrams on hand (which you should absolutely have), what is common to all of these codes? I recognize a few of them, MAF, evap solenoids, O2 and it looks to me like you are missing a power feed that is common to these systems. Again, face value stuff here

p0010 and p0020 are vct solenoid codes you can use a noid light or test light at the connectors at solenoids and see if the solenoids are getting power and receiving ground side control. using the koeo self-test you can prove power and grounds and ecm control. if noid light lights up and shuts off the circuit is good. if not then some digging will need to be done to find out why no power or ground (fuse, short, wiring etc)
p0461(fuel level sensor a circuit)
p0443(evap purge valve or control circuit)
p0446(evap tank vent control circuit)
p0191(fuel rail pressure sensor circuit)
p0155(bank 2 sensor 1 o2 heater circuit)
p0131(bank 1 sensor 1 02 heater circuit)
p0113(intake air temp sensor1 circuit)
p0102(mass airflow sensor circuit)
given all these are circuit codes i would look at wiring diagrams and see what all shares the same power feed and where the ground is for all these circuits.
diagrams are available via
www.eautorepair.net or www.alldatadiy.com it runs 20 bucks for thirty days of access or you can pay for a year and up to 4 years for a bit more
