Question o % inj duty when cranking?

car ran fine last weekend. went to crank her over today and wont start checked voltage on all conectors all is good. felt maybe replace 2 injector relays. still cranks but no fuel going to motor. pump is getting voltage. should i check ohms on any sensor. hey banzai if you read this and have any thoughts. please feel free. im running pfc on my 90 n/a. grounds are good.

You have 12v power at the injectors? If you do then it could be a CAS issue. It is what tells the coils and injectors to fire.

You should have 12v and 0v. if you have voltage on the trigger wire from the PFC there amy be a short in the engine harness.

Question

well started up after work today. maybe was moister somewhere? we had a couple days of heavy rain.but now its breaking up low. i also noticed my dash lights cutting out the past couple of weeks when i drive. could that possibly cause a short?

If your dash lights are cutting out, then you do have a short. I don't know how the two are related.
