My 96 Grand Cherokee Limited had been hard to start and when started would barely run for a bit until it "caught" and then would run normally. Then it refused to start and was not showing any fuel pressure at the rail so I swapped a spare rely for the fuel pump relay spraying the relay socket and the relay spades with contact cleaner when I swapped it. Then it started and ran with 50 PSI fuel pressure, but when I shut it off the pressure dropped to zero within half a minute. Now I do not hear the pump priming when I turn the ignition to run and it still takes two or more cranks to start. I think it used to prime for about 4 seconds when the key was turned to run and if it had sat for a long time I would turn the key on and off several times before cranking and it would start right up, but now I don't hear the pump running when I turn the key on..

Is there another relay I need to check for the prime cycle?

Sorry about the typo in the title; I meant not priming. I find no way to edit the title.
