Please help, J120 starting problems

[Guest]

Hi,  I'm new to the forum. I need your help please.

I've got a 2003 Landcruiser 3lt J120, that won't start. It cranks over.

It's had 4 new injectors, new diesel temp sensor, new suction valves, new fuel filter.  Sometimes it will start, sometimes not. It's getting worse. Once it starts, it runs fine. No miss firing, no lack of power and it's not smoking. 

Any thoughts please, pulling my hair out. Many thanks

Glow plugs? Ignition timing, timing??

Thanks for you reply. ☺️

The timing has been checked and it's spot on. When it does start it start it runs fine. It sometimes won't re start when warm. If anything it's worse when warm. So didn't think it was the glow plugs 🙂

We've noticed that when it has been running, and we turn it off. We have to wait 3 or 4 minutes before it'll start again. It's got us and some mechanics scratching their heads 🤔🤷
