Welcome to AF.

For fuel filter: Under vehicle, center, below trunk area, near fuel tank, mounted in fuel line.

Check fuel pressure at the fuel injector rail. There is a Schrader valve where you can connect an automotive fuel pressure tester.

sounds like your going to have to put a fuel pump in it and you have to drop tank to put it in...sounds to reason that you spray starting fluid and it'll run. good luck...scrapper1
