The starter works fine and the vehicle makes the mimic to start but it doesn't. The battery is at full capacity (I've tried other batteries too). The fuel tank is full. The transmission is in Parking. There are no blown fuses. All of the coils and the sparks have been tested on a 4x4 Vitara (not Grand) from 2003 and it started well so I assume they are all working rightfully. I tested the voltage on the Grand Vitara inputs to the coil of the sparks and they were the same as the ones in the 2003 4x4 Vitara. However, there was one test that failed. There is a little tool to test the coils which sparks a little orange light when igniting. The light turns okay on the 2003 4x4 Vitara, but it doesn't on the Grand Vitara. The thing is that the coils and sparks of the Grand Vitara work okay on the 4x4 Vitara yet they don't appear to be working on the Grand Vitara (no spark is made at all even though their inputs show the right voltage when trying to start the vehicle). Does anyone know what might be wrong? Maybe the computer?
What engine, state engine size and country.
there can only be 3 ways, to fail.
bad engine (low compresssion, us the $20 tool at WOT and see over 170psi.
Bad spark
bad fueling.
just because spark coils (COPS?) work on other car , dont mean much.
what counts is your car , its a system.
the cops, have fast 5mS pulse when firing, you using a scope to see that?
Im so curious, why not to the time old test, use a real spark plug
attached to the COP end, spark plug shell grounded to engine metal
and crank, is spark good x4? or x6 if V6 (engine NOT STATED)
is it? then spark is good, leaving fueling.
do not touch the spark plug cranking, it can hit 100,000 volts.
I use a ground strap on the spark plug casing, hands free, or you can be hurt bad, by the spark or when you jump and cut arm backing off
on cars that flood, is it flooding?
I found my engine compression good, then found all 4 sparks fire good.
so i pull the fuel pump relay. killing fueling.
i then use "test fuel" to start engine (again, text book tests)
I use the new CRC brand of test fuel with top end oiling.
i spray it in the plenum, and it starts.
if the spark plugs are bad, (part oftune it up)
it may not start if flooded,
use WOT at the throttle (cuts fuel) and start any flooded engine.
if the spark tips are black and stink of raw fuel (wet with fuel)
that means flooding.
pull the fuel pump relay ,test fuel runs for 3 seconds. each time.
3 second spray max. each time.
if that works out, then find reason for flooding if flooding.
if not flooding, you find dry sparks.
then trouble shoot no fuel.
fuel pressure not near 30 PS?
fuel pressure too high say, 60, it will flood for ever.
there are only 3 tests.
and 4 counting wet /dry sparks.
the tests done, will put you on the correct path every time.
no guessing, no swapping parts to other cars.
SOURCE: won't start not even click
I am pretty sure you have a bad solenoid on your starter. Sometimes if you tap on them while someone holds the key in start they will make contact and it will start. Best solution is replace solenoid. You can check it by having someone hold the key in start and measure the voltage from the small wire to ground, if it is bad you will have voltage but it will not even click. Hope that helps you.
SOURCE: No power to the spark plugs
Check first the wire connections to your ignition unit. Are they properly plugged? If all wires are good, try to measure the voltage from one of the wires to the ignition unit while the ignition key is in "on" position. If there's no voltage, have someone check your ECM. If there's a good voltage reading, try replacing your ignition unit with a good one.

u need a diagnostic tool to check if there is any error codes and take it from there
SOURCE: engine doesn't start. Fuel, fuses,spark plugs,
have you tried checking compression? fuel and spark are good but if theres no compression you wont have anything
SOURCE: 2001 Suzuki Grand Vitara cranks but won't start
use scantool to diagnose the problem... maybe some sensors don't work.
