As some of you know - Drew's rig has not been running properly the last week or so, and slowly it has been getting worse and worse. No power, sputter, hesitating etc. First time it happened, I found one of the fuel line clamps was lose and was leaking... ugh!!!
But it kept happening, to the point where last week he had to drive to school in low range and home again. So I pulled the codes. Came up with and O2 sensor issue, trans overdrive (which we do not have) and some other seat belt switch or something. Kinder came over to play in the garage Saturday and try to troubleshoot the thing. Checked for vacuum leaks, nope all good there. We replaced the O2 sensor - no difference. Checked the fuel pressure - just fine...
Only thing left is injectors right?
So I pulled the intake off, fuel rail and injectors and cleaned them up real well, even soaked them overnight in BG 444 (Saw it on the internet so it has to be true, right?). Then I put a new fuel filter the size of a coffee can inline under the truck. I blew the fuel lines out from the filter to the intake so all clean again.
Sunday morning I cleaned the injectors even more, blew concentrated air at 75 psi through them both ways, replaced the O-rings and seals and put her all back together. Sunday afternoon I took her for a spin and guess what?
All good again.
I then put the BG444 in the gas tank - no sense in wasting it - that stuff is expensive.
If it happens again - I am getting new injectors but the price for them is nearly $350 for all 6 and that is simply not in the budget today.

Before the tear down:

How this didn't leak is beyond me...

Upper off, now mind you - this is the deepest I have ever been in this engine, never even removed the fuel rail previously.

Going to be extra careful with these connectors, I am getting tired of wiring isuses

Fuel rail and injectors removed:

First I cut some fuel line that fit over the injectors and poured some BG-444 into each line, topping it off and let them set for 3-4 hrs. From what I saw on the internet if any of the levels changed that is a sign that injector is stuck open. I left them in the rail as a stand (yes I saw this on the iterweb too...)

All good with the first soak so I pulled all the O-rings off and put them in a can full of the same BG-444 (this is what I saw too....) and let them soak overnight.

Before the overnight soak this is what they looked like, O-rings intact and all:

O-Rings off and ready for the soak:

Post soak and getting the new O-rings and seals. 3 done, 3 to go.

And then..... after about 3 more hours
My work was done
