50lb_cat will become famous soon enough

Start off with a fuel pressure and leakdown test. Go to autozone and rent a pressure gauge (you leave a deposit and get your money back when done) and hook it up to the schrader valve on the fuel line under the hood.

To do the test: turn key on but engine off! Initial psi should be around 60 with no leakdown during the first 10 minutes. Post back your psi numbers. Both the initial and how much leakdown and after how long.
