Okay so randomly yesterday my truck decided that it didn't want to start after i got home from work

So i did a little research and i came up with a STC fitting? or dummy plugs and all of them saying to check them but how do i do it? Any help would be nice thanks! the truck is completely stock in the motor if that helps any of you guy

What led you to believe that it may be your STC Fitting or Dummy Plugs? STC Fitting is located in your HPOP. Dummy plugs in your Rocker Boxes. I wouldn't go pulling anything apart, I'm unsure how you would test them. How did the truck react when you put the key in the start position while it was cold?

I probably won't be much help with this, so here's to bump! Good Luck!

the only reason that i think that it is the STC fitting is because all of the cases that i see sound just like what my truck is doing, it cranks for a good 40 seconds before firing when it is hot but after letting it sit all night it fired right up like it normally does when cold.

So am i correct with it being STC? and if it is how hard is it to change it out and buy a new one??

Ok, so if nobody wants to help I guess I will

lol

You are most likely correct in thinking it's the STC fitting or your dummy plugs/standpipes.
But, you should find an AE first and check the ICP pressure first. Your oil pressure needs to get up to 500 PSI before it will even think of starting... The AE will show you if it is getting up there and how long it is taking.

Now, to replace the STC fitting you will need to take out your turbo and the oil pump cover right under the turbo bracket in the back of the engine. then the fitting is right there and easy to change out. The only problem I see is if you still have your egr cooler then you need to take apart the whole top of the engine to get the intake manifold/egr cooler out because the egr cooler interferes with the removal of the HPOP cover.

If you don't have the egr cooler it is SOOO much easier

Now, for the standpipes and dummy plugs it is more work. you need to take off the plastic valve covers. Then you will see the steel weird looking pipe and the dummy plugs are the plugs in that pipe. There is one standpipe in each head and when you take off the oil pipe assembly you will see the standpipe starting for there and going into the block.

Are you sure about a having to take the EGR out? I watched a video on how to change the STC and he just loosed some hose clamp and pushed it out of the way and it came right out, I also asked my ford garage and they said that it shouldn't cause any problems. So idk just food for thought lol

Thank you master!

Just joking now looking back I think you are right... I just didn't know any better the first time.

Now that blue hose just spins 90* and comes off, then the egr cooler pops out of the intake manifold and comes out.

So do you understand everything else?
