Hi, new to the forum and look forward to any and all help with my caddy related issues. I have a 1993 Eldorado w/4.9 liter. can anybody help me out with my fuel issue? I have 20 psi at the rail, I have read that it should be around 50. Is this a fuel pump issue? I have thrown a bunch of new parts at this and am left with this. Its a big job to pull the pump and I just want to be sure of the fix before I attempt it. Thanks for any help .
