Why replace the one most expensive part, that never fails.?
$500 buck guess too... wow !
would not fuses be the first check? and wiring connectors pulled.? or not seated right? (Prev. owners, messing with struff?)
how long is long, 1month , year, decade?
no year stated, wow.
and at least V5 is stated , this is the H25 engine.
I restore old cars now, (retired, so seen it all)

  • bad fuel
  • bad fuel packs up filter , and then packs the 10micron internal to injectors tiny screens. doom.
  • you said no start, but ILL assume it cranks robustly, RIGHT?
  • I then check for spark x6 , if no spark work that.
  • I got spark x6 , so next is fueling, so i use TEST FUEL.
  • It runs for 3 seconds and stops. ah , fuel system failures.

watch scotty here and post your results. GAS engines.

I have a 2004 FSM and account so can get
all facts and all p/n of all parts on car.
fast. and have a car same.

The car has and OBD2 scan port. why not connect a real scan too
there and look for DTC errors, the CEL is mostly USELESS unless dead keyon.
the CEL if for smog.
the Scan tool shows all errors. scan it. why work blind?
also using live data stream, with tool crank engine for 5 seconds
and look for live CMP or CKP sensor errors. ( many so called pros dont even know that trick) check TPS action key on.
Is ECT sensor (and IAT) reading near ambient air temps?
it can starts so those 2 sensors read ambient. if not they are bad.
or disconnected. etc.

post my tests results and year.
get cause fast.

Haynes don't cover that engine. I've found a copy of the H25 engine manual which is similar to the H20 engine we have. If you search for SQ416 in google you'll find a copy you can buy or if you're lucky you'll find a free download somewhere like I did!! :-) It has helped me loads.

Engine light is on on the dash of a suzuki vitara v6 2002 automatic

you must test this procedure. God bless you
When you turn the ignition ON before starting the car, the "Check engine" light is supposed to come on indicating that the engine computer (also could be called ECM, PCM, or ECU) is powered on. If the "Check engine" light does not come with the ignition ON, it's possible that there is no power coming to the engine computer (e.g., due to a broken wire, faulty main relay, burnt fuse, etc.) or that there is a problem with the engine computer itself.

07 grand vitara starts then putters and dies. No check engine light is coming on! So can't check code? Answers?

No check engine light is coming on!
it must key on, MUST, or the lamp is bad or you lost power
to the ECU.
I have a 04 GV with a 6v , do you? and what country?
thats right dead CEL is dead power and OBD2 tools will be dead
cant talk to a no power dead ECU, not now or ever.
If in USA it is in fact OBD2 car.
so if all this is true. check the fuses first.
as always.

2004 Grand Vitara won't start

the trans only blocks cranking so we can ignore the overdrive lamp.
when car will not start, (state , what engine you have first)? 2.0L I4 or V6?
the first thing to check is .
is the gas tank above 1/4?
is there spark. on all 4 to 6 spark plugs.
are all fuses good.
does the CEL lamp glow key on, if not the ECU/PCM is dead and there will be no spark or fueling ever. but fuses can blow and disable ECU.

Car konks out and check engine light come on.

The check engine light is because all check engine light codes are caused by components that affect emissions. It's not actually an engine problem, it's a problem with either your O2 sensor, MAF sensor, fuel/air ratio, pyrometer, or exhaust.

2001 Suzuki Grand Vitara cranks but won't start

Most likely your timing chain.
This is a major problem 99 -05 V6 GV.
The Timing chain tensioner failed.
When the chain breaks it destroys the engine.
Unfortunately is an "Interference" engine.
This and the rear main seal are the big problems with these cars.
