1990 Ford F-150 Fuel pumps run continously

I am stumped! When I turn the ign. on the fuel pump will continiously run. It should run for about 2 seconds which it does when the light resets. It does'nt matter which tank. I have a CK Eng light on and will not let me read codes until the fuel pressures up which is intermittently at best. The fuel pressure is 40 and the fuel filter is clean. I did get to get codes at a couple of times which were 85 EONR (c) and 65 EOR. These are flash codes as I don't have a code reader.The fuel is running so rich you can almost see the gas guage go down. I replaced the FP relay and the FP regulator. I also have OD not working and feels like I'm pulling a mountain when taking off. I have the EO4D.
At times when the CK ENJ. lite goes off, everything goes back to normal except for burning very rich.
The inerta switch is good.
In order for it to start quickly, I have primed the throttle body and it starts right off.
When the accellerator is depressed, It will backfire and miss, pop and sputter!! I have added a 52cm Throttle body just after pic.
Any help will be GREATLY APPRECIATED!!!!!!!!
