Hey guys so I've rebuilt my wife's engine all fresh ect. It's taken 3 years I know a hell of a long time. Connected everything up she turns over but not firing. So I assumed spark so got new spark plugs, on taking the old ones out they where bone dry. (New ones in anyway) I depressed the Schrader valve on the fuel rail to see if there was pressure. She squirted out. What can I check next?

Kind regards
