1990 560 sec wont start
 

hey all im new to the forum. i just came into a 1990 560 sec and i cant get it to start. its been sitting for a year plus... fuel is low but i put 2 gals in it to make sure. will run on starting fluid so im pretty sure it has good spark. has fuel to the fuel distributor or whatever that thing is called. not really sure how to tell if the injectors are working correctly. other than that i am at a loss of what to do. i am thinking it must be fuel related but i know almost nothing about this type of fuel injection. almost looks like its mechanical.. anyway any help is greatly appreciated.
thanks
Jack
