What is spring sign showing on dash of seat Ibiza sport 1.6


hi Marc

SEAT Ibiza glow plugs heating warning light - your SEAT Ibiza is equipped with an automatic glow plug system. The indicator lamp lights up while the glow plugs are preheating. If the engine fails to start immediately, the glow plugs have not finished preheating. In this case, keep the clutch pedal depressed (or keep your foot on the brake if your vehicle has an automatic gearbox) until the engine starts. (applies to diesel cars only)

Need to know firing sequence of glow plugs on a 2006 chevy 2500 hd duramax diesel engine


I am told the glow plugs heat up in "firing" order, also the Duramax uses a intake air heater to warm the air on cold starts.

Car wont start when engine is cool


sounds like a glow plug problem,if it starts o.k. when warm,but not when cold,does it smoke a lot when trying to start it cold,if so i would say your glow plugs are either burned out or theres no power to them when you turn on the key,do you see the glow plug light on the dash,it may light,but that doesn,t mean the glow plugs are getting power

Surf 1KZ-TE Diesel wont fire


Typically, the glow plug light not coming on indicates that you have some bad plugs or poor connection. You need to replace the plugs and check the wire connections. It is interesting how picky diesels are when they aren't warm.
Hope this helps.

Car wont start diesel engine Could it be the 'glow plug'? what is a glow plug? how can i test?


A glow plug is a small heating element in the cylinder. It heats the diesel so that starting can be made easy. Is your car standing in the open frozen parking If yes, then it would require a lot of battery power to first heat all the cylinders and then turn the engine to start. What we do in such conditions is to light up some fire under the car and heat the fuel system enough for the diesel to warm up a little and thus save the battery for glow plugs. Generally, all vehicles have an indicator light which comes on when the glow plugs are ready for starting. The diesel will ignite on compression, but it has to reach the cylinder and thus has to be flowing. In cold it freezes and hence the need for glow plugs and the heat. If it is parked in heated parking then the need for glow plugs decreases.

I have a 2004 excursion diesel drove it all day stoped at a clients turned it off for 20 min came out and wont start the starter is going but its just not firing could it be a fuse I dont smell fuel but I...


Ok well the glow plugs on a diesel have nothing to do with the engine firing. All the glow plugs do is heat up the combusion chamber on cold starts. Diesel engines fire using high compression. An oxygen sensor won't cause the vehicle to not start and your diesel doesn't have one of those anyways. It could be a fuel related issue. (pump, line, pressure etc.) Have you it scanned for engine DTC's? But based on your knowledge of your diesel vehicle i'm going to suggest you take it to a shop.

I HAVE AN 84 TOYOTA 22R DIESEL AND WHEN ITS COLD IT WONT FIRE BUT IF I PUSH START IT IT STARTS RIGHT UP?GLOW PLUGS?


HELLO THERE:
Diesel engines work under heat of compression meaning that when the fuel is injected into the cylinder and is compressed during the compression stroke in the cylinder it heats up untill it fires.
If the engine is now starting and you are letting the glow plug on for the reccommended amount of time than yes i would consider getting a glow plug that has a higher temperature range on it.
also you can get fuel heaters this is what we use on all of our big rigs they are better know as pre heaters they work very well when the temperatures are very cold and of course a block heater works well too ok
I hope that this is very helpful for you.
Best regards michael

I have an 1983 HJ60 Diesel Landcruiser with 4.2 N/A Diesel Engine. During the day it runs fine and starts fine. First thing in the morning it just keeps turning over without starting until the battery is...


have you fixed this problem? if not ,here we go ,hj6ocruiser had 4lt a,2h engine if you have a 4.2 ltr engine in yours it will be ,a 1hz motor and a bugger of a job to fit(i have only done one and even though i have been asked i wont do another) the point being ,with out modification the 2 glow systems are not compat able the early 2h had 11 volt glow plugs then they went to 6 volt with a largeglowplug in the manifold (manifold heater) the 2h did chnge to the superglow system but not untill 1995 (in australia anyway) if you did not change the timer you will find you burn out glow plug s pretti regularly. if you brought it to me ,iwould remove,check and re place (where necessary)all the glow plugs and the manifold heater .then run an independant 12 volt wire, after disconecting the existing feed to the manifold probe, the new wire runs through an
independant switch fitted on the dash board to the manifoldheater.there
is no doubt in my mind that this is the soplution to your problem----- the quick fix is asquirt of aerostart into the air cleaner as you co to turn her over or else loosen the wingnut on top of the air cleaner a teaspoon or so of petrol at wingnut and fire her up, aerostartis best ,if you can let me know how you get on i`d appreciate it youdoit
