Hi! My friend and I have experienced similar problem with each of our Suzuki Grand Vitara 2000 (his) and 2002 (mine). He discovered (two years ago) that cooling the "camshaft rotary sensor" by pouring (normal) water (which I also did just last week) and it works to start & run the car until the next pull-over. You have to redo pouring water if you stop the endine and does not re-start. But this may be just an emergency solution wherein you have to let the car be serviced by a mechanic.

It's camshaft position sensor, located at the top-back side of the engine near the firewall. It's a black plastic bolted into its metal assembly which is bolted to the engine (Google it, you'll find the pictures)

To confirm, pour water on its metal housing so the sensor cools down and start the car, if it starts fine, replace just the sensor. Suzuki might ask you to buy whole assembly with the sensor, don't buy.. It's useless.

This sensor just loses its magnetic power over time hence can't work properly when heated up.

Cheers.

2001 2lt grand vitara. When engine is hot it sometimes will not start until engine has cooled. Also very lumpy if it does start, any ideas please


lumpy is misfiring. that be it.
ever do a tuneup this decade? even spark plugs?
the above implies it runs great cold. and running long distances
but if parked it has what is called in the business, heat soak, hot restart failure.
ever use scan tool. and plug it in (after a tune up) and see if there are
DTC errors.
and when wont start, TRY WOT , that is , wide open throttle cranking
per opr. guide, this clears flooding. does this help. it?
did you examine spark tips to see if fuel soaked (flooded, or jet black)????? check for spark , yet?
when dead.
lots more, ....

Problem with restarting after sitting for half hour.


ever get a tuneup this decade?
is it flooding,
the operators guide says, crank wide open throttle to clear floods
does that work? y/n
if NO check for lost SPARK when it DONT start.
bingo?
if spark is good and not flooding does starter test fuel start engine.
for 3second, not at all , or runs. now.//??
this works on all cars. otto cycle.

Did they figure out if you are loosing fuel or spark when it fails to start up ? You would need to know which to proceed.

2002 suzuki grand vitara not starting when hot have to leave it 15 minutes before it will start again


what engine, 2L I-4 or 2.5L V6? post engine, for best answers
or Post VIN, or open hood (USA) look up see EPA vacuum sticker. that tells you the engine type.
ever do the 60,000 mile tune ups, 120k, 180k,etc?
1: after the tune up.
Ill assume it cranks robustly but does not start hot.
2: does using the op guide recommended WOT method start car
when dead? ( press right foot to floor, crank , bingo it starts)
If true that means it was flooded. post back if true.
3: if it dont start WOT (wide open throttle)
that means, its lost spark or lost fueling.
so check for spark using a new , gapped proper test spark plug.
got spark? no , post bad, Ive no spark hot.
4: gots spark but will not start. so use test fuel.
starts now>
A: for only 3 seconds, it runs but then stops. each attempt.
yes, then you have fuel pump issues, (no didnt say bad pump!!!)
no, engine issues. hot motor , has lost compression?
yes> post compression on all cylinders warm to hot. WOT.
or watch scotty do it. (oldest story on cars, ever, no start , 100 years)

I have a 2002 suzuki vitara.It starts and runs fine but when I slow down to stop it will sputter and then stall. ANy ideas?


If you haven't done so recently, you may want to install a new air filter. Lack of enough air to the engine can cause similar symptoms as lack of enough fuel. The air in very important to the engines performance

If that doesn't fix your problem you may want to have your, " Idle air control valve." looked at.
This part generally costs between $50 and $80 on most vehicles.

Good luck!

My 2003 V-6 Suzuki will only start and run when the engine is cool. When hot, it starts for about 2 second then shuts off. Engine check light does not come on and it showed no codes when the computer was...


The ignition coils are the usual culprit, they fail when hot, sometimes the module itself is bad, you need an Ignition specialist here, don't Shotgun (Replace parts till it runs)

My suzuki vitara has check engine light on and is ok for water and i put oil into it as seemed bit low, but it wont start at all. pls help


Check if there's a spark in the cable going to the distributor. If there's none then you may have a problem in the ignition system components. A defective air flow sensor can also cause a no start. If spark is present, you may want to visit the fuel system of your car.

Suzuki grand vitara 2000 model the engine light blinks


Take your rig.. drive it to a gas station.. fill the tank up with gas.. also fill 2 jugs of gasoline at the same time... put the jugs in the back of it.. now drive as far as you can until the rig runs out of gas.. then, take the two jugs of gas.. pour it all over the rig, inside and out.. now light it a-blaze, then walk to your nearest car dealer and buy a new car..
