This problem will has been happening off and on for awhile now, I have had the injectors rebuilt, new fuel pump, new fuel shutoff solenoid, relays are new, fuel filters are new, oil and temperature sensors have been bypassed and still no go. Please help, help, help, plyscamp?

When you say fuel pump are you talking the main pump or the lift pump? If you are getting any air in the fuel lines it will do what you are saying. I got rid of my lift pump (The small one near the front of the engine) and replaced it with a 12 volt electric pump. If I get air in the lines which happens when you run it out of fuel, its a PITA to prime the system with the manuel pump. With the electric pump you mearly loosen the fuel fitting were the fuel line enters the main pump, turn on the key and let the electric pump push fuel out of the fitting until it runs solid with no air bubbles. Tighten the fitting while it is still pumping and start the unit.

You stated that you changed/ rebuilt the injectors, make sure you have no air leaks at any of the fittings. You can still prime the system with the lever on the manual lift pump but its a PITA.

Let me know if this does not help, Gordy
