glow plug light

[Cross]

my wait to start light flashes after first started that mean glow plugs are needing changed

The glow plug light will cycle a few times (usually 3 or so depending on outside temp) after the engine is started. That is normal.

hi, my truck has not cycle a few times ( sometime one flash )after the engine is started...and is very hard starting! ..bad idles for 2-3 second :confused:


realy or glow plug??

Extra flashes depends on outside temp, mine rarely gives an extra one, outside temp 60°F. If your temp is much lower then the controler is the problem.

i had a 96 2500 with a 6.5 brand new and the glow plug light flashed along with the headlights,i now have a 98 and it does the same thing, i would say it is normal,

I noticed my headlights flashing right after i started the engine too. I too, think its normal.

Bad batteries really mess with GM radios. Dad's Buick had a radio with a mind of its own 'till he changed the battery. Wife's suburban had a radio loose it's memory like the battery had been disconnected, but was not...
