I have a 2000 F250 7.3 and I have a ton of white smoke coming from the exhaust. I'm not making oil and the coolant is clean. I have replaced the CPS, starter solenoid, and put in a new battery. I believe it is a stuck open injector, but I'm not sure how to test for which one it is without bringing it to the dealership. Any tips?

Is it doing it when you start up and then going away after it warms up, or is it always smoking.

Did you replace both batteries or just one? In these trucks your suppose to replace both, even if one tests ok.

It's always smoking. It started as soon as I took it off cruise control on a 490 mile drive. I replaced one because the previous owner had just replaced the other one.

This is my first diesel also so I don't know that much about them. Anyway I can test to find out which one without pulling each one? How could I test for a bad nozzle?

I don't think it is a stuck open injector. That would cause a darker smoke like it would be running rich.

It could be a injector oring

Any check engine lights

No check engine light. I have used a scanner from advanced autoparts and there were no codes.

X2 on checking for blow-by.

On a side note, advance auto and all the other parts store's scanners won't work right on diesel trucks. They have different codes than gassers.

A good diesel shop can run a contribution test and injector buzz test to help diagnose.

Can you go into more detail of the "it won't turn over"?
Does it try to turn over?
Does it make any noises when trying to turn it over?
Does it loose electrical power when trying to turn over?

It starts to turn over and makes a little noise. I also lose interior lights as it's trying to start.

Go back to checking the batteries. Sounds like one is bad, not charged, or not making good connection. I would first use a voltage meter and check battery voltage when the lights are on and then when cranking. If the voltage is low (below 11v) then you need to check the battery circuits. When testing these batteries, you need to unhook one of them and then test. If they are hooked together, a good battery can hide a bad battery. If they are good, you need to look for bad connections which are usually hot when used due to high resistance.

Your injectors won't fire if battery voltage drops below a certain value which I think is 10v.

easy way is with a scanner, hard way is pull the valve covers off and unplug each injector one by one while its running and see if smoke goes away.
