Default Fuel pump doesn't engage with ignition

I have a 1989 Cherokee 4.0 automatic... Its been sitting for about 6 months ran fine but now wont run unless ignition is in start position and full gas. I cannot hear pump run when turning key.
I have replaced Ignition relay,Ignition Switch, Ignition control module,Cap, Rotor, Plugs, and wires
Also I bypassed the ballast resister.
I use a power probe 3 to energize relay and pump turns on. I energize ballast resister and pump turns on
I energize starter relay pump turns on,
I replaced all relays but I tried to jump terminals with paperclip but the pump did not come on
I am lost I cleaned all ground and connections
any help would be great

Pump only runs for a few seconds to prime then shuts down until started...
