Injectors cause hard start?
My 2002 F450 7.3 won't start unless the heater is plugged in for 2-3 hours+ regardless of the weather. Today I did a cylinder contribution test and at first cylinder 2 got code P0266 (Injector Circuit Contribution / Balance Fault) and cylinder 7 got code P0281 (Injector Circuit Contribution / Balance Fault). I drove it 10-15 miles and did another test. Only Cylinder 2 got code P0266. No error on cylinder 7. I've used RevX with some success before, so I'm tempted to try it again see if it clears up the error on 2. My question though can injectors be an explanation for my hard start situation? (I've already replaced EGR, ECP, Fuel Filter, CPS and glow plugs seem to be fine also).

How many miles are on the truck?
What are you using for a scan tool?
Is ECP the same thing as ICP? If so, please let us know what ICP you are seeing whilst cranking.
Please explain what EGR means to you...EBP sensor?

Yes, it could be the injectors. However it could be many different issues that are significantly less expensive than injectors.

Sorry, I meant ICP instead of ECP. EGR is the EGR valve.
Injector Control Pressure=2200 PSI / Volts = 2.8volts / Duty Cycle= ~39%

Go to POWERSTROKEHELP.COM - The Information Source for Ford Power Stroke Diesel Owners & Mechanics)
Watch the videos on ARCHOIL. It will tell you what you need to know. Order the product through Powerstrokehelp (they have the cheapest price and the give money to a veterans group that trains GI's in diesel mechanics
There is one video specifically about injectors in 7.3's Bill Hewitt shows a hard start 7.3 They add the Archoil and run the truck 20 to 30 miles.
Here is a link to the video
Go to Jay Leno's garage and he did a segment on Archoil. One of the executives from the company is in the video and he explains what the product is.
Also, many of the Diesel magazines and web sites have used the product and have reported on it.
I run it in my truck and several of my cars. I also run the Archoil fuel modifier.

Do you mean IPR instead of EGR? Our trucks (thankfully) do not have an EGR.
As for the powerstroke help guy linked above, I personally, and many members here don't pay too much attention to him. At the very least take what he says with a large pinch of salt.

A 16 ounce bottle and a shot of fuel modifier save the owner of the truck a few thousand dollar. But if you are rich just get the new injectors.
