will injectors make a truck not start?

I have a 1999 F450 that won't start when the temp is under 40deg. I had them check for codes and they said the 2-6 injectors were not working. They changed the harness and checked glow plugs and gpr and said they were fine. When I do get the truck started and it warms up the 2-6 injectors work fine. Do injectors start working once the truck is warmed up, and would this be a reason for the truck not starting just on cold days? After the harness was replaced last weekend the truck didn't start again. Please help!

It really sounds like you need a complete set of glo plugs 2-6 wont fire cold with defunk glow plugs causing a no start cold ...also remember glow plug on time will be significantly shorter (under 10 seconds ) which is not long enough @ low temps to fire any cylinder cold with 2 or more defective plugs

Glow plug removal



See the white wire? Pull it with your finger and then use a 10mm 1/4" drive deep well socket to remove it.

If this helps any I just went through a 6 month long cold start, no start running like crap problem. It was in and out of the shop replacing parts here and there thinking we'd fixed it (see the list below for everything I replaced before the injectors finnaly fixed the problem) and it would still act up. It was throwing a 1316 code and would not reset or clear. It would always start once it was warm, but if the temp was below 40 and the truck had been sitting for more than 20 hours or so, it would not start. I'd plug it in and it would start right up. The glow plug system was fine. My mechanic insisted the injectors were ok that they passed several buzz tests and contribution tests. We did replace one injector that didn't pass. Finnally after doing everything we could think of and nothing got better, I talked him into taking the injectors out and sending them to Industrial Injection in Salt Lake City Utah 1-801-972-0476. They were able to take the injectors apart and inspect them and they found that the insides were scared and worn beyond repair. The poppets were scarred and there was very little to zero clearance in the armatures. I Replaced the injectors with a set of stock injectors from Industrial for $220.00 a piece and walla, the truck runs like a brand new truck. The engine even sounds smoother and runs like a top. Starts in any temperature now, no problem. They told me that dirty oil will scar the poppets inside the injectors. Give Industrial a call and talk to them, I hate to say it but you might need new injectors if everything else is ok.
