[QUOTE="Fouledplugs, post: 425287, member: 18666"] You keep replying with very vague replies. And not answering my questions. I cant be of much help without you helping me some more. Again, just because the relay clicks doesnt mean its 100% operational. The relay needs to be checked visually and tested with an ohm meter to verify that it is 100% operational. And just because the fuel pump comes on and primes up to 40psi briefly and then loses it doesn't mean the fuel pump is 100% operational. We dont know what the factory fuel pressure should be. I believe there is something in the pump that’s job is to keep pressure at the rail. What year is your YJ and what engine is in it? [/QUOTE]
