BB code injectors.most swear by them.i like mine.probably would have liked a fresh set of E's just as well i dunno.
factory turbo engines got the G codes.
if you want to see what others say about all the codes just search.im done repeating info i don't know about personally.i can't tell you BB's blew my old E's out of the water or anything like that.they fixed my issues with shot injectors is all i can tell ya about 'em.didn't seem to do nothing less or more.perhaps if i had my turbo installed (still isn't.) before and after,id be singing a different tune.
whatever you decide,you can get 'em all here:
7.3 L Ford Diesel Fuel Injectors Fuel Pumps Accessories
if you want a real performance injector you can get 'em here:
IDI Products
i know Dave S run those with great results with 20 lbs of boost setup.
probably not what your after without their pump,head studs etc.cus id think you'll just over fuel and get nowhere lol.

New IP and old injectors? Well, there's your problem. They are most like popping at the wrong time because they are worn and could even be leaking constantly. I would throw in a set of reman or new injectors (if you can find them) and see how that goes. Pickup a bag of Viton #111 o-rings because you will need to install new o-rings on the injectors.

I just got a good deal on a 7.3 idi f250. Hard to start when i bought it. So: all new glow plugs, injector seals, and sealed an air leak at the fuel filter.
Now it starts every time. When its cold i have to crank for 15 sec if i dont use the block heater. Great truck!

When you changed the ip did you pullthe whole housing off (the part with the oil fill tube on it) or did you pull the 3 bolts under the tube? These bolts would have the star type head on them. Then pull the 3 nuts on the housing? If you pulled the entire housing with the gaer in it you may have got the timing out on it. I did this rookie mistake when I first put mine together. It would start but rolled raw fuel white out just like yours did.

The head studs give a better clamping force on the heads than bolts do. It will also allow you to run more boost. The pryo Allows you to monitor your exhaust gas temp. This this a must before turning up your injection pump and is just a good general thing to have.
94 7.3idi, if you pulled the whole housing with the gear in it then you have some work ahead of you. There are timing maks on the drive gears for the crank that match with a gear on the cam. Then there is also a mark on the cam gear that lines up with a mark on the gear that drives the ip. These marks must aling. Since you din't pull the cam gear all you have to worry about is the is the timing between it and the ip gear. I had a time trying to see this mark on the cam gear as it is just below the front cover behind the water pump. I hope some one a little more computer savvy than I on here will see this and give you a liknk to one of the many threads on it. I used a small dental mirror and a good flashlight to find mine while turning the engine over by hand lol. Remeber that you need to unhook the fuel shut off valve as it may start. It is also a good idea to pull the glow plugs to relieve the compression while turning it.
