YJ fuel issues after rebuild....help!

I am trying to wrap up my rebuild on my '93. Clean fuel tank and new fuel pump. The engine will start with starter fluid then die. I am checking the fuel filter next. And ideas? 4.0 injected.

Check to see if your fuel lines are plugged. You can do that by putting a air compressor on one end and disconnecting the other and blow her through

No fuel to the fuel filter. I'm going to drop the tank and start over I guess. Maybe try switching the hoses from the fuel pump first. And I do hear the pump turning on. Is there a priming issue?

No priming issue the feed and return lines may be backwards. Ask me how I know.

Ok. Got it all down and apart. It's the connector coming out of the fuel pump. Any tricks to keeping the connector from separating the pins/wires? Or is a better connector the answer?

At the wire terminal on the pump, or the 3 pin connector outside of the tank?

@ the 3pin. Plug won't stay together within the plastic housing on the fuel pump end. The wires pull right out of the back.

Go to any of the parts store and get a 3 pin weather pack connector.

Can anyone draw me the schematic of the plug connecting the fuel pump to the system. Wires pulled out of the plug and I'm lost!

You can get a generic weather pack plug from the parts store and match the wire colors. If the wires pulled out the detent that hold the wire is probably shot.
