Welcome to tne forum.

Even though you say the resistance is good to the Glow Plugs. I`ll place my bets that the Glow Plugs are your problem. You need to remove them, and put 12V to each one and see if the tips get good and hot (red). hold them with some pliers.

Also be good to get ahold of a GP Reamer and ream out the GP holes of Carbon.

Since you are new to diesels, Iam assuming you just bought this SD and working your way through the various systems. sounds like you have done your home work and ben doing some searching here for info. At the top right of the page is the Resource Tab, in there is the DIY Articles with pictures on various jobs, and DIY links listed in catagories.


Diesel Giant has a good write up on troubleshooting the GP system.

We are advised to NOT judge ALL Muslims by the actions of a few lunatics, but we are encouraged to judge ALL gun owners by the actions of a few lunatics. Funny how that works
