Can I be forced to purchase faulty car?

They have identified a fault and are having it fixed before you collect the car. That sounds like a garage that does the right thing. I’m not sure why you’ve lost faith in them, it sounds like they are checking what they sell actually works as it should.

You can’t be forced to buy it but you will likely lose your deposit.

I saw a second hand car I liked and put down a deposit. I was due to collect it today and the garage have said there is a fault on it and they have sent it to another garage to be fixed. They will update me when this has been done but it's made me rethink whether I want the car. I have signed a sales sheet but not, as it turns out in the correct place and I have paid a deposit.
Can I change my mind as I have lost faith in the car and the company?

Why have you lost faith in the company?

They discovered a fault and are correcting it. !!!!!! they’ve even told you what they’re doing. :wall:

Seriously run away. Find a car without any problems. If you take it reject it immediately if it is not absolutely perfect or just find some reason to reject it within the time limit.

There are plenty of used cars. I would want one that had been properly serviced and that worked perfectly. I have had cars that needed expensive repairs and every garage has said 'trade it in'. People have cars with intermittent problems that can't be fixed so they trade them in. So these cars are then sold on as second hand cars. Expensive repairs mean lots of disassembly and careful re-assembly. I have never experienced a garage that has been capable of doing that. Once a car has been seriously taken apart by a garage it is never the same again. There is a chance this car would be OK but I wouldn't risk it. I would move on. Injection on diesels = expensive. Fuel injectors for my diesel are £480 each.
