glow plug questions
 

first off i wana introduce my self, my name is Alex im not new to the fourm but i am new to the powerstroke side of it. i recently got a 2000 f250 crew cab 4x4 7.3 when i got the truck the guy told me the glowplugs need to be replaced he gave them to me, ive done glowplugs on my old 7.3l idi non turbo but not on a powerstroke, where r they located and what do i need to remove to get to them and how do i take them off.

under the valve covers.. IMO check the Glow plug relay chances r that it has failed. could save u lots of time. IIRC the boost tubes to and from intercooler need to be removed not sure as i have not done them on a SD just my truck. google the glow plug relay or check here


:tu:

how do i check the relay. and are there 2 of them because i was looking at my friends 2000 psd and it looks like there are 2 gpr i could b wrong

heres a link that describes how to test it all https://www.dieselbombers.com/ford-d...tml#post537961
Im not sure if there is 2 or not i dont think there is but someone else will chime in with that answer

haha i found our answer here https://www.dieselbombers.com/ford-p...tml#post666694 lol but the answer is ..... The Early-99 has one glow plug relay. The later 99-03 has one glow plug relay and one air intake heater relay side by side. Both relays are on the passenger side valve cover toward the front of the truck.

Glow plugs are under the valve covers just beside each injector. If you have some time, I would swap them since the guy gave you the glow plugs. Its good insurance. Make sure the guy gave you Motorcraft Glow plugs. Don't use autolites or any of that other crap, they swell up and make removal tough... For the GPR, a quick test is to jump it with a screwdriver across the two big terminals for 30 seconds, then jump in the truck really quick and try to start. If it starts better, The GPR is bad.

If you have a voltmeter, do some of the testing that shorty's link has...Let us know what the results are.

ill do that this weekend, and yes the glow plugs i have are motorcraft.

thanks for the info on the two relays but which one does what

The one towards the back of the engine I believe.

Front of truck, "left" side of the valley, 2 relays, front one is Intake heater relay, back one is the glow plug relay.

DO NOT short the terminals of the relay, great way to help destroy it.

Go to Harbor Freight and spend 3 - 4 bucks on that cheapy voltmeter that seems to be on sale all the time (has a ton of uses on your truck) set it to the 20V DC setting, put the black lead to the negative of the battery, use the red to probe the 2 larger lugs on the relay, one should have 12V with the key off, go to the other one that has no power with key off, have your buddy turn on the key, if that lug doesn't now go to ~12v your relay is crap.

alright thanks im deffinetly going to get on it this week. ill let yall kno how it goes.

i always use a test light find a good ground the pasenger site terminal should always be hot have some one put the hey to the on position if the test light lights up on the other side the controller is good if not well you know the rest.
