get fuel pressure test. one when cold , one when warm. review when last tuned . it may be due. rec. fuel system clean. ethanol treatment to 1 tank fuel. build up in fuel system can cause starting issues.
re placed fuel pump, Filter, and IVM...not getting any pressure at the filter going to rail..I also unplug the harness and ran pump straight from battery, still no pressure. I does start and run when I spray starting fluid into intake.. what could be the problem? Also how much does it cost to reprogram all modules since I did not have this problem until the battery ran completely down..
