I bought genuine Traxxas plugs specifically for the TRX 3.3. Chubaka, what do you mean by lay the plug on the cooling head?

Take the glow plug out of the motor. Hook the blue ezstart wire up. Put the plug on the cooling head. It's still a circuit, just on top of the fins instead of in the hole. Without touching the plug hit the starter. It should glow orange in the bottom coils.

That was my way of getting rid of "bad plugs". Ofcourse some of those were tossed for engine issues.

Ok got it, I will check with that. if it still won't light is there a way to make a DIY glow plug igniter?

Use the glow plug wire. Wrap the wire around the connector after unplugged.

I've already tried that trick, nothing happens...

If you have a detachable glow plug wire like this below.

You put the glow plug wire on the center of the plug. That side gets connected to positive. Take a piece of wire, strip the end and wrap the bare wire around the outside of the glow plug, attach that end to negative and you should get a good glow plug to glow, bad will not glow.

Ok, I'll try that

Take a rechargeable AAA battery and peal off the outer plastic coating, then take the battery fully charged and place it positive side on top of your glow plug and let the side of the battery touch the inside of cylinder head and it will light up your glow plug...

didn't work, nothing happens

Buy new plugs. Take them oit of the pack wnd test them. See if your test is faulty or if its the glow plugs.
Its not totally incredible that your plugs burned out if there was no fuel and power heating them for a long period of time.

I almost got it started, I smell nitro exhaust so it's getting there, how can I tell my glow plug harness is all the way on?

for some reason the engine can't get past the top of the stroke after tightening the glow plug
