Yes
First thing

i believe there is another fuse for the fuel pump in the engine bay. did you check that one too?

 

I checked that one to its good everything keeps leading me back to eic but Im not sure how to check it other than buying a new one

 

got me beat, have to ask somebody who knows a bit more man, sorry

 

There is the possibility the Oil Pressure switch either is bad or disconected.
Real PITA. Its back by the distributor towards the drivers side. Its there to stop the motor in the event of an oil pressure problem.

The pump works when you jumper it right?

There is also a quick disconect near the underhood fuse for the ECM/Fuel pump.
You can unplug that and plug it back in and it should reprime the fuel system.

Good luck

 

Just slap a mechanical pump on there...
