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?
