Injector swapped
- Thread starter BigRed94
- Start date
With the truck running, carefully loosen one injector line. Listen for a difference in the way the truck runs.
Then tighten back down. And move on to the next injector.
Do this all the way around.
Every injector, once loosened, should make a difference in the way the engine runs. You should hear it. And probably see and feel it as well.
If the engine doesn't change at all, when you loosen an injector, then you have found your bad one.
Put one of your old ones back into that space, and see if there is an improvement.

I appreciate it so much!
You are most welcome!
Also, watch for the flow of fuel from each of those, after you loosen them.
If you identify the "bad injector", and there is no flow when you loosen the line to that one, your problem may be in the line, or even in the IP itself.

Thank you, I’ll be check that tonight. I think my injection pump is worn out.
Don't sell the IP short, too quickly.
If there IS a delivery problem, try this... Probably a good idea to do it regardless, just because it is a good thing to do.
Remove the fuel filter from the housing.
Either empty it, or get a new filter.
Fill it with ATF. Just plain old ATF.
Re-install it. Now get the truck running again, and run it ONLY until it becomes obvious that the ATF has made it into the IP, and hopefully the lines.
Turn it off, and let it sit. At least overnight. Better if a couple nights...
This should clean up the IP, and lines.

I will try this tonight, I need to drive the truck tomorrow morning, so I’ll only be able to do one night of atf.

Did you change the injectors for the same issue, or did it start after the swap? New injectors or remans?
