6.9 turbo, bad startup

[texasdually]

im going to go look at a 6.9 turbo f250 1984

the guy says it the glow plugs arint grate, causing it to start up poorly... the truck ather need to be pluged in to start up or needs to spray ether down it so it can start.... i wondering is that truly bad plugs or could it be something more serious.... i dont belive that the block needs to be heated up to start cuz its over 100degress so the block shoudl be plenty hot down here in texas?

your right. shouldnt need to be plugged in.
I know nothing about 6.9's but heres a bump for ya

The glow plugs are probably no good, you can check them pretty easily. Just pull the connector off the glow plug where it screws into the head, then touch the blade with a 12 volt test light connected to the positive terminal of the battery. If it lights, the plug is good, if not, its bad.

but motor will run if u can start it, just having hard times... i mean has anyone had this problem before and ditermind it was the glow plugs... seams strang it will run all day just having problems on the start

[85F250Diesel]

yeah, that's exactly the problems my truck was having when I bought it, dude. none of the glow plugs were working.

BTW, if you end up having to replace the glow plugs, ONLY USE MOTORCRAFT/BERU GLOW PLUGS!! Other brands are prone to swell in the head. I had problems with this as well.

weres the best place to buy the plugs... should i replace the wires like u woudl on sparkplugs??? how much all this cost?

[85F250Diesel]

I found that dieselfiltersonline.com had the best price for the glow plugs. 8 bucks apiece I think. There's no need to replace the wiring unless you find that its got shorts in it or anything like that.

You may find on trying to remove some of the glow plugs that they are stuck, having swelled as I mentioned before. If this happens, and any of the tips break off, you might have to remove the head to get the broken pieces out.

thanks so much

[85F250Diesel]

No problem, dude, glad to help. Good luck, I hope you find a truck you like!

it might be the plugs, our 88 idi has been doing that when the block is cold. replaced the plugs and gpr and starts better. now if the plugs arnt the prob then its something else.
