Diesel Fuel Injection System Help Desk

You don't have to bleed the high pressure lines to the injectors if you are able to successfully start the engine after a fuel filter change.

Nag leak ang injection pump (TD27, A/T) so binaklas, palit seals and calibration
Nung binalik na sa akin, sobrang erratic ang shifting, hirap magdrive pauwi. Pero pag nilalagay sa Hold/Snow mode, medyo nagiging ok ang shifting

May mga nabasa ako na may relation ang isang sensor sa injection pump na nagcocontrol ng shifting, so sinabi ko yung sa mekaniko ko. Pwede yun nga daw and kinuha nya kanina at ibabalik sa calibration shop. Kasi suggestion nya una eh mag change ATF, kakapalit ko lang last change oil (5k kms) and nung iniwan ko yung sasakyan, smooth ang pag shift

Any ideas Dieseldude? Thanks

Tama ka. Posible na hindi naitama ng calibration shop yung setting ng potentiometer. Test specs ang kelangan para tama ang lahat ng adjustments.

hello dieseldude,

electrical problem lang pala ang issue. sa starter switch. nawawalan ng supply ng kuryente ang shut off valve kapag nasa "Start" position ang susian. buti hinook up ko sa tester. 12 volts kapag nasa ON. once na ipihit sa START, zero volts na. wired up with a relay muna yung shut off valve habang wala pang makuhang replacement key cylinder

Hi, my ride is adventure 2006 diesel glx. Kanina lang, nagwild yung techometer ko (tachometer, not the engine). Taas-baba sya for a few minutes. Then nag ok na, hindi na naulit.

May naka encounter na ba sa inyo nito? What to check?

Hi DieselDude,
2 Quick questions if you dont mind.

1. Is there any adjustment to increase fuelling on a 1999 elgrand (Higher boost wanted from turbo) - I have been told I have plenty of fuel available, but the same shop also increased my boost by simply unplugging the wastegate actuator pressure hose...sigh..so my faith is a tad low atm..(Very expensive, and big name shop in Makati area that will rename nameless)

2. My car is idling a bit low and shaking shuddering..a 100rpm increase applied at the pedal fixes it nicely.. Would the idle adjustment be on the Zexel pump? Or is this a case of TPS adjustment?

Hi Dieseldude,

2008 model Santa Fe maingay yung engine, parang helicopter, sumasabay sa rev ng engine.

regular oil change with a FS oil. me kinalaman ba sa injectors ang ingay? nasa passenger side yun ingay around the belt area.
possible ba na conn rod e nasa left side lang yun malapit sa belts?pag injectors ba maingay din?me slight vibration na rin ko na fifeel during engine shut off e.

possible ba na magpost ng audio file dito to have a better feedback from all the gurus out here?

Check for faulty engine speed sensor and/or harness connections.
