Hello all, having an hard starting issue 05 Tahoe Z71. Checked fuel pressure, drops rapidly. Disconnected fuel line to rail, still drops. Figured fuel pump since it's never been replaced and live in Minnesota. Replaced fuel pump with Delphi Fg0808, surprised anything was working with how corroded everything was. Also replaced half of fuel line. Thinking I solved the problem and after test driving, the very next start having same issue. Pulled injector rail, nothing leaking. I'm now frustrated and lost.
Could I have gotten bad fuel pump? Can I have a leak without smelling or seeing gas? Any ideas greatly appreciated. Ty!
