I am tired of thinking about this car. ('81 Bertone) See link below for 5 years of discussions on all the problems.
I drove it to the paint shop and back about 3+ years ago then put it on HF jacks stands to age . . . and finish off all the cosmetic work. Heart valve replacement and a torn rotator cuff later it is time to get it off the jack stands.
Starts on starter fluid.
Hooked up the TurboBricks brand fuel pressure test equipment and only get 20 psi at the Control Pressure Regulator with the valve open and that is close . . . but . . . with the valve closed I get the same reading. Should be 70 psi. Both pumps are running in 'start' and jumpered at the fuel pressure relay.
Both lift and pressure pump have been replaced since I tried to pump 20 years of gas tank rust through them some years ago. Remember, it ran 40 miles to/from the paint shop since anything was done to affect the fuel system.
Other than spraying gas everywhere the fuel distributor to CPR connection is the only place I know to open the system to test pressure. A hose blew off the V8 conversion project at 90 psi and dumped a gallon of gas in about 5 seconds so I am aware of what that much pressure will do. I ran.
Since I replaced the original completely failed pressure pump with a cheap universal pump that probably cost $20 on ebay that didn't even physically fit I upgraded to a $30 pump that did fit the mounting hardware. Bench tested it before installation. It is marked + and - so got that correct and it is pumping some gas.
CPR reading with valve closed remains 20 psi. My logic process says that even if severely restricted the pressure should have gone up over a minute or two.
The only thing that I can think of that would maintain a steady inappropriate pressure is that the fuel distributor pressure regulator is stuck open to some extent and dumping all the pressure back into the tank.
Commiseration and thoughtful analytic comments appreciated.
