how long have you had it plugged in?

was the engine warm to the touch?

[97-Stroker]

plugged in over night. should the engine be warm after its been plugged in over night? i plugged it in at about 10 pm and went out to start it at about 630 am.

Thanks

it should have been way warm by then

did you open the hood and touch the engine to see how warm was it?

you will know if it works when you get a couple of 10 degree nights and it doesnt start lol

Most of the time after you plug it in you should be able to hear it making noise(sounds like faint popping sound) a few seconds after being plugged in. It should also be warm to the touch and a decrease in frost towds the bottom of the windshield.

what the last guy said.

[sikktruk01]

the temp gauge should show a slight reading if it's been plugged in for more than a few hours,
mine temp gauge will read 1/4 if it's not below 28 or so after being plugged in for several hours

After it's been plugged in overnight, or even for a 3-4 hours open the hood and feel either the upper radiator hose or the hoses going to the heater core. If they're warm to the touch, it's working. If not, something's wrong somewhere...

Well i let it sit over night again plugged in. and its not warm...the wait to start light stays on forever and it barley starts. I replaced the plug cause one of the prongs cracked out of the original one...did i wire it up wrong?? does anyone have the wire diagram. There are 2 black wires and 1 green but the plug that i got has 1 green 1 whit and 1 black...

So i dont know if i wired it right...any help on that would be great. Thanks!
