An LPG 2.2L that cranks but won't catch, or throws a code halfway through a shift, rarely explains itself; the 299-page Utilev Mazda 2.2L LPG Fuel System Parts and Service Manual PDF (OEM ID 76001979, 2012) covers that LPG fuel system from regulator to ECM. Engine wiring schematics for both LPG and gasoline versions show the harness routing, and the diagnostic scan tool chapter walks you through live testing before anything comes apart. DTC coverage runs from crank and cam sensor codes such as DTC 16 through throttle position, injector driver, oil pressure and adaptive learn faults up to DTC 2126, and the fuel system chapter ends with ECM and Electronic Pressure Regulator replacement. Confirm primary fuel pressure at 2.0 to 4.0 psi, then torque the EPR to its bracket at 14 to 18 ft. lbs. A regulator swap stalls when nobody knows the inlet line torque. Bookmarked and text-searchable, your copy travels wherever the truck sits.
