Barn find siitng for 20 years prev owner spent $10G on dealer engine rebuild 40 K ago but rust in body & chassis . Got it going by pouring petrol down the air intake , got fuel pump going but suspect the injectors stuck , trying to find info on check procedures for the early Bosch EFI system but cant find anything. the Haynes manual is no help .

 

Welcome to the forum! Maybe it's time to seek the help of a mechanic.
