Crank no start no gauges?

Yes I did I tried a different computer as well with the other computer I have fuel and spark but still wont run and still no fuel or amp gauges but I has fuel and spark so should run u would think ne ways

Haven't tried starting fluid cuz u dont have ne

So I swapped put the computers and now I have fuel and spark but still doesnt run if I spray starting fluid into intake it will fire but still no gauges and still not running

Yes it kicks on also ive jumped the relay over to stay running still wont stay running

Gas is good pulled a fuel pump out of a running truck still nothing getting thru the injectors into the cylinders fuel rail has tons of pressure constant can dump gas down the intake and it will runn for a second or two then die something is wrong with injectors they aren't firing or something
