Thanks Tony!!, You were right!, I opened the rectangular cover, found three spring elements were stuck or compressed, I used a screwdriver to pushed down, made a pop sound and came back to the right position!!, One of them took me several times to get it decompress, then opened the switch, pushed the heaters button for ten seconds, pulled the starter lever and started right up!!, first start after 20 years!
I have the car running for several days,it makes a lot of smoke, I planning to replace injectors,my question is I have been trying to get new injectors with no success, there's only one place on eBay but they don't send to United States, do you know any place that I can get new or rebuilt injectors for this engine? Any help will be really appreciated, thanks again!
