bkdrocks Posted January 12, 2010 Share Posted January 12, 2010 Ive checked every sensor and replaced with know good ones,Checked every ground,and still no luck. Idles poor if at all,won't maintain rpm's with throttle pushed,over fueling I think? Until 2 days ago it was running perfect,am I over looking anything? won't have fuel pressure gauge until the am,but I have fuel pressure just don't know how much. HELP!!!!!!!!

bkdrocks Posted January 12, 2010 Author Share Posted January 12, 2010 Forgot to mention if I remove the vac line to the MAP it will idle? i don't know it if its because I created a leak or if it has something to do with the MAP or MAP curcuit??

Pete M Posted January 13, 2010 Share Posted January 13, 2010 is the Map sensor a known good unit? Quote Link to comment Share on other sites More sharing options...
WBKrazy Posted January 13, 2010 Share Posted January 13, 2010 ya try swapping the map, if it runs fine with it disconnected that should be the problem Quote Link to comment Share on other sites More sharing options...
bkdrocks Posted January 21, 2010 Author Share Posted January 21, 2010 It always goes back to something simple...Fuel pressure,rubber line from pump to pick up tube was sitting against the end of the pick up tube,getting fuel up top to rail but wasnt building pressure(9pounds) I had replaced the pump but the hose was a straight piece with the new pump i reused the curved hose..Looked good when I didit but on inspection when i pulled the pump back out the hose was swollen up....new fuel line in tank and I'm in business. I learned alot about the Renix system and I'm kinda glad I did,not as leary about keeping it in the truck now.Was considering swapping it out in the future.
