What are the signs of a glow plug relay or glow plugs going bad?

 

fast solinoid cicking, or no click at all

 

thats exactly what its doing. where can i get a new one and a set of glow plugs and wires?

 

cant get the wiring harness, have to make your own. your relay is most likly fine. it it just the plugs that are faulty. they are around 10 dollars a peice. DO NOT GET AC DELCO, CHAMPIONS, OR BOSCH! only use International, Motorcraft or Buer glow plugs. i belive u can get motorcraft plugs at adanced and autozone. u want part number ZD9 for motorcrafts.

 

im an electritian so making the wire harness will be easy. ill probably get the motorcraft ones if the dumbasses at advanced can find them.

 

I'd start with just replacing the glow plugs as the controllers on the 7.3 aren't prone to failure. Bad glow plugs will cause the fast clicking as the increased resistance will make the controller think they are fully heated up.

 

I would change the moduel under the GPR mine was bad and was giving me all kinds of problems.Advanced autos had the GPR and moduel in one for $102.00 Wish I would of changed it sooner

 

Pulled Autolite and Champion gp's out of mine and replaced them with Motorcraft's that I got at O'Reilly for about 11 and some change each. FYI: Talked to Oregon Fuel Injection about the BB code injectors being on back order and the said that they are shipping mine on monday so, apparently they finally got them in stock again. Pass that info around.
