Without a lot of information, you are asking a very difficult question that I don't think anyone (myself included) is going to be able to give you a definite answer to.

First off, what is the model year and mileage of the vehicle in question? I'm assuming it has a 6.0L in it, since you posted your question in THIS forum.

Secondly, does this vehicle have any modifications?

Third, what were the specific DTC numbers retrieved?

Fourth, and this may sound like a stupid question, but what is the condition of your batteries? Believe it or not, low battery voltage will cause all kinds of funny symptoms. I prefer the "KISS" philosophy (Keep It Simple Stupid).

For what it's worth, any 6.0L that has landed in my hands with a DTC set for a specific glow plug has always ended up being the GPCM (Glow Plug Control Module) needing replacement (Ford part number DY-876).

07 f350 with 120000 mile,stock dont know the dtc just told me #7 glow plug i will have my batteries checked.how about the front wheel speed sensor is that fairly simple

Okay, that helps a little. Has this truck had any recent repairs? The left/front wheel speed sensor DTC should be a fairly simple issue to figure out. Check the resistance of the right/front speed sensor and compare the reading to the left/front. If both give similar readings, you need to check for shorts or opens on both the circuits leading to the left/front wheel speed sensor between the ABS module main connector (in the engine compartment near the brake master cylinder). Just look for the matching two colours on the ABS module connector to isolate the circuit. If all checks out good, you need to replace the left/front hub and bearing assembly (the tone ring is all one-piece with the hub and bearing).

As already stated in the previous post, the most likely cause of cylinder #7 glow plug DTC being set, would be the GPCM. That is a fairly simple repair that you can easily tackle yourself.
