Electrical?
Getting spark and the fuel pump is working. Checked fuel pressure by pushing valve on fuel line just before the injectors.
Had to jump it or spray starting fluid during cold weather after it sat overnight to get it to start. Once started it would start all day. Ran without hesitation. Battery checks out. New cap and rotor. New spark plugs and wires.
Put injector cleaner in tank last week now will not start or stops once it burns off starting fluid.
I'm stumped? What do you guys think?

I borrowed a fuel gauge and I'm getting 30-35 psi after replacing the filter.

Guess I'm looking at the fuel pump again, which is a royal pain to get to. Last time I dropped the tank, this time I think I'll pull the bed.

Thanks for the fuel gauge advice.
