I’m mostly sure the L-jet bits are in working order, at least the resistance on sensors and what not. I believe I have the grounds all clear, (2 top of aux air, 1 #4 injector, 3 next to fuse block, 3 below shift boot, 3 drivers side tail lamp, braiding below trans case, and finally the main battery connection). Please let me know if I’ve overlooked. I did begin with a new battery and charge it before trying…. The old battery was quite tired. I usually float around 11.4V-11.8V through most of the testing before recharge.
Excellent suggestion on the fuses! I had replaced the fuse on the passenger side that is inline to the coil. I had failed to notice the extreme corrosion that the holder had. Retracing my steps I went ahead and tested continuity of the line from the second relay to the terminal on the coil as was getting intermittent results. Cleaned and refurbished the connection, was real hopeful I would have something, but back to the drawing board.
Through testing I have gone and cleaned up the plugs a few times to keep them out of the equation.
The car was parked for a bit from the previous owner, I believe for 3 years. I am told they had planned and put stabilizer in the tank. Not sure what product, if it was ran through the injectors or if it never happened. I believe there was an issue with the fuel pressure regulator, the vacuum had some fuel coming out the top. I’m trying to grab a pressure gauge to make sure all is well off the fuel rail. Ill post results once I have a chance.
I’m hesitant to call the injectors bad just yet. When I do get spark and a short run, I am able to rev the engine up and after the usual sluggish start it runs smooth (10 seconds). After I get a run though it seems to flood out and will resist starting for a few cranks. If I wait about 10 minutes it will usually crank and run once again. Would the ECU have some sort of safety feature baked in for engine oil or temp that would cut the engine? Here in about a week or so I’m replacing a cracked fuel rail on the 83 so I’ll have a set of known working injectors though I have no idea how to refit the hoses. They look compressed, but I’m sure with a little googling I can stumble through it.
Anyways thank you for the help so far. I’ll keep posting as I learn more.
