1hz hard to start when cold - 2000 Toyota Land Cruiser

The problem could be worn cynlonizers on gear 1and2 or sleeve for 1st and 2nd gears

I believe u have a variable valve timing sensor controlling your timing, COMPUTER CONTROLLED) If u are trying to adjust your timing , FORGET IT! Scan the ecm & ck ALL sensor readings that could affect your timing. Coolant temp, O2, VVT sensor etc

If you're comfy with manuals then i know few websites that can help you with it. Bcause I've bought
it from various websites so I know how each site deals. try www.reliable-store.com Very helpful

what country.? makers do use diffr. engines in diffr. countries.
what engine,(that be first on the list, to start)?
70 or 80 series LC>? just a hint.
the wiki list:
Diesel:
2.4 L 2L diesel I4
3.4 L PZ diesel I5
4.0 L 2H diesel I6
4.2 L 1HZ diesel I6

4.2 L 1HD turbodiesel I6
4.5 L 1VD turbodiesel V8

which one.?
then learn the injector and glow plug controls. (books)

the "basics of Diesel)

1 bad glow plugs? (lots of ways)(or power or controls)
2 weak compression (a cold engine need max here)
3 or bad fuel injection. (or no air supply, clogge air filter, or?)

to solve problems you can do simple tests.
it's all in the manuals.
if you learn what engine you have, you can get all that facts
you need by googling just that.
who knows, it might save you $15 buying a book.

you need to check the relay on it...

better chec the wiring or connections 1st--pull the plug from the pump and inspect for flaws and corrosion then plug back in--pump itself can be tested--the fuel injection pump in engine area may have issues

Landcruiser 100 vx, 2003 model with engine number 1HD-FTE is not starting, I've found out that the fuel pump, starter, battery are all functioning well. Where next should I look at.
