1996 KJ Ford Laser 1.6 will crank only No start

[Darren@63]

Went to start car, will only crank but won't start. So far have checked battery and fuses, tested ok. Replaced distributor and have power at 7 pin plug on distributor. Replaced fuel pump (and have power at fuel pump plug) and replaced fuel filter as fuel line dirty between the two, still won't start. Have checked the fuel pump regulator and relay also seem ok. Can the knock control be an issue not sure how to check this one, it is under the bonnet and is a small black box 40 x 40ml bolted to mudguard near the air cleaner which has a plug. Running out of ideas, can anyone suggest something I may have missed.
