NewZed Posted May 30, 2014 Share Posted May 30, 2014 Saw this column this morning and thought it looked like BS. Maybe the original Click and Clack have sold their identities or the whole thing is just a show. MIT graduates? The implication is that there's a pump that pressurizes the fuel tank, It would have to be an air pump that pumps outside air in to the tank. Sounds like total nonsense. http://blog.nwautos.com/2014/05/randomly_running_truck_is_confusing_owner.html?prmid=obnetwork Quote Link to comment Share on other sites More sharing options...
Domzs Posted May 30, 2014 Share Posted May 30, 2014 Agree . Those guys don't know wth they're talking about . There's no air pump to pressurize the fuel tank in that truck . I put my money on the ABS module , common problem on GM trucks . Quote Link to comment Share on other sites More sharing options...
ctc Posted May 30, 2014 Share Posted May 30, 2014 My buddy's 2000 Trans Am had a similar problem, with his emission system. Can't remember if it was a pump or solenoid, but it was loud and annoying. Quote Link to comment Share on other sites More sharing options...
NewZed Posted May 30, 2014 Author Share Posted May 30, 2014 (edited) They got me. Apparently, there is actually a pump that pressurizes the tank. so weird that I didn't even search first. No wonder cars aren't getting lighter. I think I'll avoid all cars post-1995. http://www.autozone.com/autozone/repairinfo/repairguide/repairGuideContent.jsp?pageId=0996b43f802d818d Edit - although, it doesn't appear the the GMC Sierra uses one. So they were almost right. Edited May 30, 2014 by NewZed Quote Link to comment Share on other sites More sharing options...
Domzs Posted May 31, 2014 Share Posted May 31, 2014 Dodge trucks and some cars use LDPs but not that year GMC truck . They need to do some research before giving ( guessing ) out advice . Quote Link to comment Share on other sites More sharing options...
