Even if the fuel system was primed and had ran before, it still would hard start with the circuit issue.

Not on an LMM. On an LB7 or an LLY you would be correct. Because they have 2 injector drivers in the ficm that alternate firing the injectors. But on an LBZ or LMM the ECM has 4 injector drivers. So if an injector or wiring is shorted, or if a driver goes bad, you only lose 2 injectors.

Did you finish installing your old injectors and have it running now? I'd make sure of that before declaring the injectors you bought are junk.

Exergy told me I could flush and store them with calibration fluid. It's not cheap though. 1gal of it is like $80, but I figured it wasn't worth the risk since I didn't figure anyone would buy my used fuel system.

lol well the case is being reviewed by PayPal now so hopefully it goes in my favor. Didn’t get the drivers side swapped back yet. Will be doing that today. Got new tune from mark also last night so once I finish swapping it should be good to go

Lol exergy saying if they sat for a year with diesel they are junk Is bs to you? Or the fact that it was trying to fire on one cylinder with a stocker isnít good enough?

Is there different types of this fluid? What's the process?

I have a hard time believing that storing injectors for a year, packaged correctly, would be an issue. In racing and pulling circles this is done all the time. I have done this many times and have installed my cp3s and injectors that have been sitting packaged on the shelf for over a year and have never had an issue.

Now i can see if they are left open or the diesel had water in it but i don't see blaming the injectors being stored the problem.

Looking at that photo, i can see contamination and/or rust from improper storage could surely be an issue.

Just my experience in over ten years of racing and storing fuel parts while new builds are happening.

I don't think so, but I didn't look into it to far.

climate controlled is probably a good start.
