Working on an AMC Eagle with a transplanted 4.0 from a 1990 Cherokee. It has been parked 10 or 15 years and I am trying to get it running smoothly again. I have it running and driving but it idles rough, stalls when you stop and shudders from time to time under acceleration.
Fuel pressure at idle when idling rough is bouncing from 18-30 and 30-40 when driving. No drop in fuel pressure prior to the stall. Brand new FPR and no vacuum leaks.
Vacuum pressure is about 8-10 at idle and very steady.
Current fuel pump is external, eventually going to an in-tank.
What pressure does the fuel system like between the pump and FPR? Can anyone recommend a good external pump for the RENIX?
Thanks!
