Ok I still haven't been able to figure out why I'm having so many problems after replacing the fuel filter in my C5.
First off I broke the fuel line and repaired it with a piece of high pressure rubber fuel line. Which ended up splitting.
Then the fuel pressure jumped up to 100 PSI and began pulsing. Now it's from about 80 to 100. I also hear the fuel pump when I turn the key on before cranking pumping in pulses. I just did it again and it actually goes all the way past 100.
Now it runs really bad. Or rather hardly at all. Feels like a vacuum leak.
Same pulsing but has a lope now. Huh, that's sucks because my dumb *** has been ALL OVER this car lately. And what I may of disconnected with my elbow, or beer or whatever could be anything. And I ain't spraying carb cleaner nor any other petroleum product solvent type of substance around my engine at this point. Maybe propane
feel like I should refer to this problem as a saga And the engine is an ls1 with the LS6 intake, a BBK 80mm throttle body, dynaflow loooonnnggg tube headers cross pipe huge magna flow mufflers.
Was bad *** until the fuel pressure dropped. Went down to 40 psi from 52. I have the boost gage and fuel pressure gaug in the pillar. Other mods are ??? Haven't had the car long but it's has 45000 believable miles and there is a yellow wire going south that is cing off the fuel pump relay. Think it's a voltage boost for the pump. Six speed manual.
