How do i replace a 81 mack injector pump
is your frontera using the latest diesel design, CRDi engine ? common rail ? if so, check /replace the injector driver. electronic device the controls the injector. check power supply to the fuel pump motor.(fuse/wires ,connections) check replace pump motor if necessary. injector driver is different/separate from ECU. take note: CRDi engines are also using ECU,, computer box as in layman's word. for non CRDi engine. check/replace fuel filters, check the small fuel filter near the tank if so equipped with that filter. check tank breather hose for any bent/obstruction. check/replace fuel handpump, (part where you fit the fuel filter) check for any clogged fuel tube from injection pump to injectors, worst case,, you may have to remove the injection pump for calibration service.

No it is not a fuel pump problem. It either has a grounded are open circurt. Check wiring to injector. May just be a bad INJECTOR.
