I appreciate everyone ideas.
Cmyles, Thanks for your thoughts on my mysterious findings. To answer your questions, I have owned the car for years and it sat because of a clutch issue. Last year, 2020, I resurrected it and got it running pretty well. Then it started to run poorly, exhibiting the current running problems. Due to other more pressing issues I did not get back to it until a few weeks ago. With regard to the secondary wiring, I am sure it is correct. I have never had the engine apart and the wiring harness was never removed. I do understand that number 1 cylinder is at firewall and it is number 3 fuel injector wiring when removed will always stop it dead. Literally to my surprise it will stay running with all of the other 3 injector wires pulled off simultaneously with no change in the running.
I had already considered a ground problem at the lifting eyelet. A couple of years ago I had removed the fuel rail for my injectors on my Volvo. When refitted, I had neglected to tighten that grounding bolt and it ran terrible until I discovered that oversight. On my Saab I removed those grounds a couple of days ago, cleaned them thoroughly and re-tightened the bolt. Last year I replaced the distributor wires with new Bougicord wires. I just verified they are in the correct sequence
Goblin, Thanks for your comments. Yes I very meticulously took of all of the Turbo hoses and thoroughly checked them for leaks. I was not aware of the brass fittings that go into the intake manifold and make sure they're all epoxied into the intake. Where exactly are these?
I will check the injector wires for breaks however they seem to have consistent connection. I checked with the noid light twice in the last couple of weeks. Also with the injector rail out all injectors were squirting gas.
