datsun71

i have a 1999 gsr....i recently replace a new head gasket.....at first it start and running, but timing belt was little bit off...so i redo the timing belt...now it wont start...i think do to the a injector wire that was touching ground, i accident close the vavle cover on the a injector wire touching ground....after removing that wire off...there no fuel coming....i replace the main fuse rely and it still doesnt work....

what could it be....
