1994 F350 7.3 glow plugs

1994 F350 7.3, the issue is the glow plug relay, have replaced once and daughter's mechanic says its bad again. Mechanic says that instead of replaceing the relay again, he can bypass the relay and wire the glow plugs to a button she would have to hold. I don't think this is a bad thing, its pretty much the way things used to be in the past, but with the system on her 1994 will this cause more problems?

Many guys on here have done that, I prefer getting the current system in proper order.

the glow plug system on a 1994 IDI has a controller/relay in one. you can replace the whole thing. you can replace just the relay but usually if one is bad the other is too. the controller piece tells the plugs how long to stay on.
List: Search for 'glow plug controller' | O'Reilly Auto Parts
then you have the plugs themselves. you need to make sure they are motorcraft ZD9's
Motorcraft ZD9 - Ignition Glow Plug | O'Reilly Auto Parts

the only other thing could be power delivery issues which even a manual switch couldn't prevent that you could end up frying plugs..... i suggest getting the stock system in working order.... i love just being able to click the key forward and having no extra buttons to push but thats just me

As stated above make sure that they are motorcraft/beru ZD9's. If you do a search on this site you find many horror stories from guys that used other type plugs. It could mean pulling the heads because of broken off plug tips.

While you do your search, make sure to verify exactly what they were using. The only GP that will work with the stock system is the BERU. As I stated, if you go to a push button, look into the other GPs since you can't fat finger them and burn them out. The BERUs have their limits as to how long you can hold them on. The horror storys mentioned involve GPs that are cataloged to fit our engines and they can cause problems.

PS. Actually, if you need to replace the controller, I would strongly suggest using the one from Accurate Diesel. That way, if the controller screws up, you won't burn out your GPs.
