Does any body know where can I buy the caddy disc holder

If the mirror plug has wires you can see, match these to the colours in the door wires.
if not you could pull off the other side mirror and look at the pinout on that mirror - if they are not all the same, at least the power wires should be the same colour - connect the colours that are the same and you may be able to work out the rest by trail and error.

Try another monitor and see if it acts the same way. Borrow a monitor from the next door neighbor for an hour or so or from a relative and see if it behaves the same way. If not, go purchase a monitor.

You should be able to get into the BIOS or Setup without a hard drive. Power on the machine and notice what function key it tells you to hit to get into the bios or setup.

Most laptops have a cover on the bottom that once removed, the hard drive goes there. Normally you will see 3 circular discs that represent the hard drive. You'll need to know whether your drive needs an IDE or SATA hard drive. Laptop hard drives are 2.5 inches or just ask for a laptop hard drive. Since the drive is missing the caddy that holds the drive in place might be missing too. And some laptops be it IDE or SATA uses an interface that sticks on the drive too. I think you need the help of a professional. I'd say you're looking to spend $80 - $125 just on parts depending on what is missing and needed.

What you have done so far is throw parts at your truck,
without vehicle knowledge.

If your going to work on your own vehicles ,spend the big
bucks at Helm.Com & buy the factory Powertrain Control/
Emissions Diagnostic Manual for year 2004 ford vehicles

You surely had to know as you proceeded, that all those parts
didn't fail at once & you tested nothing, to determine they were
in need of replacment.

Now you need to know why you have a PO316

Air,fuel,spark or vacuum leak.

Not easy to diagnose if you don't work at it for a living

You've got no tension on your bobbin thread, take the bobbin out and replace it into the bobbin holder ensuring that the thread clicks into the tension spring correctly. You can usually hear it going into tension and when you pull the thread up vertically, it should stay in place if its in right.

The Pfaff Expressions 2.0 is a top loading bobbin machine so you've probably just missed getting the thread into the tension device on the bobbin holder and it should be a case of just redoing it again.

However, if you find that it is in the tension spring and there is no tension going onto the thread, then perhaps you (or someone else) has adjusted the tension dial on the holder. They usually have a little dial with increments and a screwdriver slot in the top to make adjustments and it may well have a red zone marked where it should be set to. These dials usually do NOT NEED to be adjusted at all, only exception might be if you wanted to run shirring elastic through the bobbin.

Check your manual and see what it should be set to and put it back to that setting.

I hope this helps you resolve the problem and get sewing again. Obviously if you have tried all this already and know something is definitely out of whack with it then it may be necessary to buy a new bobbin holder for the machine from your PFaff dealership (or have it serviced to resolve the fault).

Current Hitachi Models use no disc caddy for the DVD disc. The 2003 and 2004 line of Hitachi DVD-Camcorders (DZMV350A, DZMV380A and DZMV550A and DZMV580A) utilize a round disc holder to accommodate the smaller design of the newer models. All previous generation DVD-Camcorders use a square cartridge. The actual discs are the same and can be used in all models as long as the disc is placed in the appropriate holder or cartridge.
