Hi, my 91 16v is currently a non runner, I hope someone here can help me get it going again.

Car broke down on the way to work about a month ago. It had been kangarooing before cutting out and I could hear the underside pump was humming when I tried to re start it, but it wouldn't start.
I replaced the lift pump, it started, I took it for a drive, all was good, I know what I'm doing, job done!

..........
Next time I go to start the car, it's having none of it!! I have since replaced the main pump and tried a different lift pump but it still won't start

I have checked the fuel line to the metering head, when I undid it I got a petrol facial so I know I've got fuel pressure up to there, but on removing the injectors there is nothing coming out when turning the key.
Can anyone tell me where to look next please?
