OK here's the deal Ive been having trouble with fuel system. fuel pump wont prime. You can here it at the fuel rail like its bubbling and the pump never shuts off. i have replaced the pump with a used but working pump from BLOWNDFIZ (http://ltxtech.com/forums/member.php?u=421), car runs quite a bit better with this pump but still not priming. I have replaced the relay and regulator and still no change. i have unbolted fuel rail and injectors and went to prime system and did not see any leaks from injectors. im completely stumped. i have ran seafoam in tank a couple weeks before it started happing. could i have possibley changed something in the tune that would screw this up or could it be a bad ecm? i know the original owner had replaced the ecm already i think he said once or three times but i really cant remember for the life of me. any ideas before i go crazy.
