1984 F250 6.9L NEED HELP
 

having trouble with my glow plugs and injector pump. i put a new glow plug controller and a new relay on the truck along with new plugs and they are not heating up. i have a full 12 volts all the way around the harness but they still wont heat up. the injector pump was removed by previous owner cause he thought it went out on him because the truck was ran out of diesel. it seems to be okay but i am having trouble getting fuel through the lines. i put new injectors and return lines on and i am getting fuel to the filter bun it seems to not want to go past the filter. any help or info on what to do would be greatly appreciated i dont know a whole lot about diesel motors so any suggestions would help.

did you bleed the fuel lines?

dont really know how to do that... i just bought new glow plugs also and put them in today i got the motorcraft glow plugs. also there is some sort of censor right by the water pump neck and 2 wires hook up to it from the glow plug wiring harness and i know one wire is hot and one is negative but i dont know if there is a certain way they need to be hooked up.

Bleeding the injector lines are really easy. Crack open the fitting from the fuel rail to the injectors one turn. Have someone sit in the driver seat and crank until fuel starts leaking at out of all the fittings with no air bubbles. Then close all the fittings. You might have air in the lines. Also I found this out the hard way yesterday that when I set the injector pump timing off by 180 degrees. The truck will not run period. Here's the link on how to set your timing. Looking at the pictures really helped.
"Talk about Timing!!"

thanx for the link ill check it out. do you know much about the whole glow plug wiring system?

I haven't had the need to mess with them yet *knock on wood*. Did you try plugging it in to the block heater? I know if I don't plug my truck in when it's cold it's not going to heat up or start.

i had to put in a block heater cuz there wasnt one on the truck when i got it. but im just trying to solve my problem with the glow plugs not heating up.

that link helped alot its got very good info
