Dieseldude, tanong ko lang po. I had my 4 nozzles replaced and installed by Betan-Makati last month (my engine is 4M40) to correct the black smoke. After the installation, wala na ang smoke. However, ngayon mahirap magstart pajero ko kahit maiinit na ang engine (so i think not the glow plugs ang reason). What i did, I stepped on the gas pedal (maximum to the floor), with this, magstart na siya after few revolution of the starter motor (around 2-3 seconds). what do you think is the problem?


Possible problems are:
  1. glow plugs or preheat system
  2. weak battery if your cranking speed is low
  3. air in your fuel susction lines
  4. injection pump
  5. low compression pressure
Btw, ano na ba ang mileage ng Pajero mo? Your engine needs glow plug assist even when hot if it's mileage is high due to normal wear on the piston rings and liners. High mileage = low compression pressure = low ignition temperature.

Start with 1, 2, & 3 before considering 4 & 5.

Good luck,

Dieseldude
