This vehicle was in here about 8 months ago found lift pump to be bad which then led me to find fuel tank collapsed because the owner had intstalled a non vented fuel cap replaced fuel tank pickup and lift pump truck was fine. Now its back runs perfect when cold once it warms up it starts to lose power, surges at idle and eventually will stall and is then very difficut to restart and wont run for more then a few seconds up to a minute. It has the following codes which keep returning when it acts up. P1218 injection pump calibration circuit (returns first). P0263 p0266 p0269 p0272 p0275 p0278 p0281 p0284 which are all injector balance faults every cylinder. Possible injection pump?
