The Glow plug warning light on - Grand Vitara

When the engine stops, the power steering stops because the engine powers the power steering pump with the serpentine belt.

There could be many reasons the engine stopped and the fuel pump is just one of them. Check for DTCs and diagnose the vehicle electronically with a pro grade scan tool computer.

Hi. I'm not sure at this point. Your information sounds like a power or charging issue. How is the battery, charging system and related wiring, cables, terminals and grounds? There also could be a fault related to the ECU. A poor connection, shorted wire or damaged component. The glow plug light shouldn't be coming on while you are driving. You mentioned that power returns if the brake light goes out. Which brake light (Dash or Tail lamps)? Are you also saying that power returns if you release the fuel pedal? Does the vehicle lose power while under a load? The more information the better. You are there and are the eyes and ears. Please let me know else I can do to help. Good Luck.

my guess it does this only cold block. right. a key fact.
glow plugs failing
just because a lamp come on , dont mean much,
actual glow plug current is what matters. (proper)
only takes 3 things
proper compression.
glow plugs
fuel.

It will work through the temperature sending unit for the engine. You may have one or two. Some companies dedicate one temp sensor for the glow plugs and some don't.

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.

there is a sensor in the cooling system for the glow plugs if it reads it is 80f it will not light the plugs ,.check to see if you get power to the glow plugs.if not go to the sensor or the computer.

not always the golw plugs can be bad and the engine can be low on compression. does it start alot better if you add a gallon of kerosene to 5 gals of desiel? Or a quaart of gas? the glow plugs can be checked with a test light the connectrs are in plain veiw and the wires going to them are big. Follow the wires back to the relay they go straight there, the relay is real close to the battery as it draws alot of power follow the big wire on the battery that doesn't go to the starter and thats the glow plug relay. they last good but the connections get dirty, reconnect all the connectors on itand see with the key on if the glow plug light comes on on the dash that wire that lights the light is the same wire that lights the light fires the glow plugs. You can take the wire off the glow plug( you need to do it anyway it's a yearly service anyway and with a test light connected to power touch the disconnected glow plug with the lights probe and the light should light, not all of them are likly to be bad but if you find two or more just change them all as the ones that aren't out are likly to fail anytime and if you want to drive though the winter you need all the help you can gt. the battery cables and the one going to the glow plug relay are likly to fail at the battery so go over this good It might start fine with just two glow plugs working I'd pick the two center cyclinders or the two outboard ones as once the engine starts it'll keep running long enough to start the other ones. low voltage as your cranking can effect the glow plugs but the relay is suposed to turn the glow plugs off at cranking and time out after they've been on long enough. dirty connections are almost always the problem so clean everthing before you replace anything. Needs cleaned before yu put on new parts anyway and the glow plugs need to be taken out with the right tool or you may end up with a broken off glow plug in your cyclinder head.

your glow plugs are probably bad change your glow plugs

check fuel filter if needed bleeding of air out, also check engine stop solenoid control if closed or not energized on ignition

That symptom is either the glow plug temperature sensor on the engine or a you have a burnt out glow plug or two.
