You will need to remove both valve covers and electrical connectors from the valve cover gasket, fuel injectors, and glow plugs. It's one entire harness per side and is replaced as an assembly. Good luck.
Take out glow plugs, replace valve covers but leave uvc harness disconnected, crank with key 20 seconds... replace glow plugs, connections.. etc.. wa la
The glow-plugs are located under the valve covers. There is a single wire that comes out of each injector harness that powers each glow-plug. Disconnect the single wire from the glow plug. Connect the gator clip of a test light to a positive and probe the glow plug terminal with the test light. If test light does not come on the glow plug is bad.
How to remove a glow pug wiring harness from a 6.0
It is fuse #22, under the hood
look right above the passenger side valve cover, right behind alternator, that is the glow plug relay.
Sounds like you need to change the glow plugs or the glow plug relay switch or both.
Fix it, or have it fixed. Have it diagnosed properly to know what needs fixing. The main possibilites are failed glow plugs, the glow plug harness could have issues or the glow plug controller.
what year model is it? Is it an IDI or DI powerstroke? with the later model powerstroke the pcm provides ground for the relay need Moore info to answer
where is the glow plugs on a fiat multipla
You have a problem in the glow plug system. You will need to test for a shorted glow plug by making a test harness with a 15 amp fuse in it and applying 12 volts to each glow plug to see which blows the fuse. You will also have to replace the glow plug module/relay which is loacted under the battery shelf under the hood. Be very careful when trying to remove the glow plugs. Only attempt with a fully warm engine ( drive it for 30 minutes first ). Do not try to force them to turn, they will break.You have a problem in the glow plug system.

if 7.3 IDI disconect connector and remove with deep I think 10mm socket might be 11mm dont rember. if 7.3 DI (powerstroke) remove valve covers and use about the same size socket. Powerstroke57> it's a 10mm deep chrome socket
the glow plug controller is grounded through the coolant temp sensor . @ 16,000 ohms resistance... normal...seems to have to have it to work. new controllers by international seem to be real resonsive. smaller electronics.
