I'm Awesome
Supercharged111 is right, the factory pump is fine. Yes, it's rated for a certain flow rate at 50 psi or something, but it will not have any problems if you run a regulator and it only ever sees 7 psi. That actually reduces load on the pump, so it will probably live a really long life with low pressure. The pump will just be bypassing the extra fuel back to the tank which doesn't hurt anything.
I don't think swapping the regulator out will fix your problem if it's actually maintaining 7 psi outlet pressure, but it will prevent you from burning the fuel pump up by dead heading it like it's doing now.
It would be much more of a pain to switch to a TBI pump or an inline pump, and if I remember right the TBI pumps have a different sending unit lock ring setup anyway and don't interchange with the tank. I could be wrong though.
Got it on the fuel delivery. Thanks gearheadE30 and supercharged111
I regrounded my grounds in the engine compartment - added two that were missing (bat to frame and frame to firewall) and cleaned up the others. I need to work on under the dash next and check the ground by the OBDII port.
This weekend, I will reshoot the timing and adjust the carb and see where that gets me and report back for the next steps.
