cold start problem

i got a problem with my 2002 ford 7.3 excrusion with not starting in cold weather such as 30 and lower un less i plug her in and wait about a hour and a half for the block heater to warm it up and help it start up.
im wonder inh if any one has a write up on the glow plugs and the glow plug relays on this motor?

ive also been told to check these things out; 1 batterys, 2 fuses, 3 starter, 4 glow plug relays, 5 glow plugs

ang help would be great full!
i need to fix this truck so i can go back up to taho with no problems next weekend to see my family!
thank you for reading this!

May be apples and oranges, but since I got the SCT from innovative the truck has been running like a champ!! 15-20 degrees in the morning, plugged in all night, only one glow plug cycle and it starts and runs like it is 75 degrees out!!! Love the SCT!

not to be a smart azz but if your leavin that thing pluged in all night it otta start like its 75 out cuz youve got that block alot hotter than 75 theres no need to leave it pluged in all night put the cord on a timer or on a plug that is switched from inside only needs pluged in for an hour before you start it wont hurt anything "but your electric bill" to leave it on all night but theres simply no need heck i dont even unwind my cord unless its gonna be 10 or so and still on turn it on for an hour topps usually 45mins or so

Does the wait to start light cycle faster than normal? If it does, more than likely a bad glow plug relay.

I am betting it is a glow plug relay, same thing happened with mine. You can do a simple test with a voltmeter, I wasnt measuring any voltage going to the GP's. If there is voltage to the GP's then unplug you harness going through your valvecover and ohm out the last two and the first two. If you get OL then they are bad. There are parameters that the plugs should be within but I cant remember right now
