Arrived as non-runner

Their latest issue arose with the 1999 Land Rover Defender, which arrived at their garage in an immobilised/non-runner state.

Using AutologicLive, Autologic’s support service, Ian contacted OEM-trained master technician Duncan Jarvis for guidance on how to repair the fault.

Ian explained to Duncan that he wanted to check the low pressure on the fuel system, and asked him to confirm whether the fuel block or fuel pump controlled the low pressure circuit.

The technician was seeing 4-bar on crank but only 11psi on the return, which he knew should be at least 2-bar.

Instant fix for fault

To begin finding the appropriate repair, Duncan advised Ian to:

– Trace the ignition supply because the ignition voltage was low

– Rule out crank sensor interference by bump or tow starting vehicle

– Advised to check the PCM, engine and injector harness for oil contamination

– Program a replacement PCM

Following this advice and carrying out the relevant checks suggested by master technician Duncan, Ian was able to identify that the Power-train Control Module (PCM) had damaged injectors due to an oil leak.

No further faults

After replacing the damaged injectors, the vehicle showed no further faults and returned to normal function.

Using AutologicLive, Ian was able to access OEM-trained support and guidance to achieve this repair efficiently, saving him valuable time that he could use on other jobs that day.
