Engine management light on ,suzuki grand vitara 2 litre turbo diesel,engine feels slugish

no year told , nor country.
sold all over earth with lots of different engines,
my guess in Europe
1988 to1998.

• 1.9 L XUD9 turbo-diesel I4
• 2.0 L RF turbo-diesel I4
• 2.0 L DW10 HDi turbo-diesel I4

or
1999 t0 2005
2.0 L RF/RFM I4 turbo-diesel
2.0 L RHW/RHZ I4 turbo-diesel
2005 to 014

1.9 L F9Q I4 turbo-diesel
2015 up
1.6 L D16AA DDiS I4-TD

no telling year, country , and which diesel is here, makes answers
10x more hard. so now I go GENERIC and vague.

1. bad fuel, now filters are bad. , water in fuel or worse./
2. clogged air filter.
3. injectors clogged.
4. newer diesels, have EFI sensors that can be bad.
5. injection pump bad or messed with and fails.
6. engine compression fails. (a test)
7. tank lift pump bad,
8. and more but no engine or year told.

old post
RTM the fsm covers all that.

you have no fuel pressure cranking???????
what is the problem. or doing the depressurize?
.
below is 2.5L GV, 99, no turbos. no diesels.

diesel? state county,
they use diff, engine in diffr. countries.
in the USA the answer is the FSM. book.
or alldata.com DIY or at mitchells.

here off the wiki, see this about diesel?
. Since 2001, all diesel 1st Gen Vitaras are to be imported from Argentina, built by General Motors in Argentina, featuring 2.0-litre HDI engines from PSA

is this it? the PSA? (wild guessing)

It may to check the glow main fuse first,while I head for my diagrams and check further for this.Let us know any info on vehicle running or starting prior to this fault.

Oil change interval for 2 litre engine is 15.000 km or at least once pr. year.

pull back the belt pully back it should fit then

The 1.9-litre diesel engine in the latest version is sourced from Renault and delivers a hefty 221 ft lbs of torque for reassuring operation both on and off road. This power makes the Grand Vitara a far more versatile proposition, with even enough power to pull a small caravan if required.

for further reference read the article :

I'd be first confirming whether you have a 1.6 litre Grand Vitara (petrol), or a 2 litre turbo diesel. The 2 litre petrol (straight 4 or V6) or 2.5 litre petrol engines are all chain drive.
If your engine is petrol then no lock tool is required (to hold the camshaft). Of course, there is a specific position that an engine should be rotated too before removing the belt from ANY engine.
If it's diesel, then although I'm unfamilar with that particular engine, the general requirement for diesel engines with high pressure injection pumps is "yes, you require a lock tool" to hold the injection pump pulley. As I think these are a common rail set-up, this requirement may not be necessary. Check with your Suzuki Dealer, or maybe someone else here will know more. A similar question may have already been asked and answered here too.

The turbo unit may have bad bearings and is ineffective. Check the throttle plate to verify that it opens all the way when the pedal is pushed down.
