Technician:
Concern:	CUSTOMER STATES THE ENGINE STARTED TO FORM A FUEL KNOCK AND WAS BLOWING A LOT OF WHITE SMOKE, THE CUSTOMER TOOK THE TRUCK TO THE DEALERSHIP AND THEIR TECHNICIAN TOLD THEM THAT THE MOTOR WAS BAD AND NEEDED TO BE REPLACED. PLEASE PUT THE TRUCK BACK TOGETHER AND RUNNING IN ORDER TO PERFORM DIAGNOSIS. TECHNICIAN CHECKED AND FOUND THERE TO BE EXCESSIVE WHITE SMOKE, MULTIPLE DTCS; P0090, P0101, P0463, P1093, U1800. TECHNICIAN PERFORMED COMPRESSION TEST ON CYLINDER #6 AND #8 JUST TO VERIFY THERE IS NO INTERNAL COMBUSTION CHAMBER DAMAGE, #8 IS AT 400PSI #6 IS AT 425PSI. TECHNICIAN SEES NO REASONABLE DATA INDICATING A BAD ENGINE. TECHNICIAN TESTED COOLING SYSTEM FOR EXHAUST GAS AND EXCESSIVE PRESSURE WITH NONE PRESENT, INDICATING CYLINDER HEAD GASKETS ARE FINE. TECHNICIAN STARTED DIAGNOSIS FROM THE BEGINNING. TECHNICIAN STATES THERE IS EXCESSIVE WHITE SMOKE, AND IT DOES APPEAR THAT THERE MUST HAVE BEEN AN INJECTOR STUCK OPEN. TECHNICIAN PERFORMED A HIGH PRESSURE FUEL SYSTEM DIAGNOSIS AND FOUND THE HIGH PRESSURE IS ONLY REACHING UP TO 16K PSI OUT OF 23K PSI. TECHNICIAN CAPPED OFF INJECTOR #8 AND FOUND THE SMOKE CLEARED FROM THE EXHAUST AND THE MAX PRESSURE CAME UP 2K PSI. TECHNICIAN RECOMMENDS REPLACE ALL 8 FUEL INJECTORS. TECHNICIAN STATES THE FUEL PRESSURE REGULATOR IS ALSO SLOW TO RESPOND, IS CAUSING A SURGE AT IDLE, AND IS STORING A CODE. TECHNICIAN RECOMMENDS RE CHECK THE HIGH PRESSURE FUEL SYSTEM ONCE INJECTORS HAVE BEEN REPLACED TO VERIFY IF THE HIGH PRESSURE PUMP IS WEAK. TECHNICIAN RECOMMENDS REPLACE THE FUEL PRESSURE REGULATOR NO MATTER WHAT, BUT TRUCK WILL LIKELY NEED A HIGH PRESSURE FUEL PUMP AND THE REGULATOR COMES WITH A NEW PUMP. TECHNICIAN ALSO FOUND A CODE STORED FOR THE MAF SENSOR, TECHNICIAN CHECKED THE MAF SENSOR AND FOUND IT NOT SECURED INTO THE INTAKE PIPE, AND THE AFTERMARKET INTAKE IS NOT CAPABLE OF PROPERLY SECURING AND SEALING THE SENSOR OFF. TECHNICIAN RECOMMENDS REPLACE THE INTAKE SYSTEM AND RE CHECK THE MAF SENSOR.
