Long Wait for Glow Plug

Hi,

Even on the warmest day I need to warm my glow plug for 20 seconds or so on my 19J engine. Is this normal or do I need a new plug?

Thanks
Ben

What do you mean by "need"? On a warm day you should not need any glow. There is a plug in each cylinder. They either work or are broken.

They could be broken and still start

Mine weren't working when it was -5 and I left the bonnet open long enough to warm the engine and it started


Hate to say it, you have another problem.

First thing to check is timing of you have starting problems.

I think I still have 4 new ones if you need them.

To check them for operation.
They must be cold.
Disconnect all the plug interconnect wires.
With an Ohm meter check plug resistance to ground.
Good pug will be about 0.5 Ohm's
Bad plug, digital meter will just keep searching

But still, your engine should start after the starter barely engages with no glow plugs this time of year.
My glow plugs are turned off, unless it's <20F outside.
