Problem starting S 14 engine car has been stored but has been started frequently and has never been a problem before.

I removed the airflow meter to clean the engine bay below , I put it all back together and now she won't start whether this is coincidental I don't know. I have checked the two relays behind the header tank they seem to be okay and fuse 11 is okay. There is fuel in the injector rail but I now need to check if the fuel pump is working and the injector system is working correctly how do I do this?
The engine turns over and nearly wants to fire up, if I spray starting fluid into the plenum chamber it far is for a few seconds but will not continue to fire up and idle, it feels like fuel starvation

Any help would be much appreciated

Bit late with this reply, but short out the fuel pump relay (30 to 87) and if it's working, you'll hear it whining away, along with general creaking noises from the fuel pressure regulator. For a more scientific result, connect up a sub £20 ebay pressure test kit.
