Mechanic has run the diagnostic but says he can't be sure of the problem. He says it might be the fuel pump so he wants to take the out the engine before he gets to the fuel pump. This will take 4 hours at a cost of £80 plus VAT but he ant promise it will resolve the issue.
My question is why can't the mechanic pinpoint the issue of why the car won't start. I understand that the four main elements needed for a running engine are: spark, air, fuel, and compression.
My car has 63000 miles.
My car has an automatic transmission.
While I cannot say I have never been unsure of the cause of an issue in my years of working on cars, this is an expensive guess on the part of your mechanic. Either work out an arrangement that if his "guess" does not solve the problem, you should not be held to paying for it, or split the cost with you. If you are uncomfortable with that, then maybe just offer to pay him for his time and take the vehicle to another mechanic.
