My glow plug light does't always come on first time I turn the key on my 2004 Accord diesel, when this happens the car just turns over and won't start. If I wiggle the key a few times the light comes on and it starts?

Replace your glow-plugs with the proper ones from DENSO.

glow plugs are activated if look on the dash when you turn the ignition just before cranking and you should see a light that stays on for several seconds then goes out and then you should crank the engine ! sometimes when its really cold or the glow plugs are worn try turning the ignition on and off each time light goes out 2 or 3 times to get more heat on the plugs then start ! if this doesnt work then glow plus and system needs checking !

this will happen as it gets colder.. preheater needs to reach temperature before starting..in really cold weather we used to turn the key on and off a half dozen times in order to get these glowplugs really warm enough to start these diesel trucks..

I drive a 2004 F-350 with a 6.0l. 5 glow plugs are out, have to start on ether when temp is below 40 deg F. CAUTION turn key on, wait for glow plug light to go out, spray approx 3 seconds, start. Should crank about 3-4 seconds then fire off. I work on heavy trucks by trade, mainly roadside service work.

When light goes out glow plugs still heating so count 15 seconds after ligh goes out the crank on key

i think glow plug replacement needed. ever used starting fluid in cold to start?try this, next time no start, cycle your key and let the light come on, wait till it goes off, turn key again until light goes off, if you have to do this more than 3 times, and it runs fine, replace the glow plugs only then. thank you for choosing fixya.com!

Are you waiting after turning ignition key on before actually moving key to start position? My diesel I turn key to 1st position;bells and lights;if engine is cold an amber light that looks like a lamp filiment comes on...wait until that light goes out before engaging the starter.

I don't believe any VW sent to the US in the past 15+ years has come with a plug-in heater. The only exception is if the car was from Canada, or if one was installed afterwards.

If the engine turns too slowly to start, try cleaning the terminals of the battery, if still nothing- replace the battery.

If the engine turns over but just won't fire up cycle the glow plugs a few times before trying to start. Turn the key to on, wait for the glow plug light to go out after a few seconds then turn the key off. Repeat 2 or 3 times before you try to start.

Also make sure you use a fuel additive for the cold months. Look for something with anti-gel on the label.

i had the same problem and it turned out to be a dirty fuel filter,am sure this will cure the problem,ps they are a nightmare to replace,take it to a dealer
