Author Message   Ulyscol Posted on Monday, June 29, 2009 - 09:02 pm:        My brother has a 2005 GMC Sierra 5.3L that is throwing a P4066 code. Now he says it won't take fuel??? I say he is crazy but he swears he tried different pumps at 3 different stations and could only squeeze in 4 gallons. He says something keeps tripping the pump like the truck is full. Anyone have any ideas?   Bubo Posted on Monday, June 29, 2009 - 09:08 pm:        need to know the vin is it a b,t,or z,or a hybrid are you sure it is a p code they don't go that high, and is the truck a 4x4 (Message edited by bubo on June 29, 2009)   Skntpig Posted on Monday, June 29, 2009 - 09:12 pm:        I had a problem on a G35 coupe and it kept triggering the "I'm full" thing on the pump. It was under warranty and it was fixed but had something to do with the vent that lets the air out as you displace it with fuel. It was mechanical, not electrical so I don't know about the code. Sometimes you will throw a code if the fuel cap won't seal. I tried to search the code but it didn't match. I bet the fuel vent is clogged.   Americanmadexb Posted on Monday, June 29, 2009 - 09:13 pm:        sounds like bad sensor? Its got more gas in it then he thinks! or, fuel sending unit. my guess is though he has a plugged vent. It could be an actual plug, or a bad vent valve. He can try to put the pump handle spout in the tank filler hole just enough to make the gas not spill out, and pump slow, he may be able to slowly fill the tank.

Looks like P0406.   Skntpig Posted on Monday, June 29, 2009 - 09:24 pm:        I could fill mine when I turned the pump upside down or horizontal instead of vertical.   Ulyscol Posted on Monday, June 29, 2009 - 09:29 pm:        Thanks everyone. I am guessing it is a clogged vent. When he removed the gas cap the tank released built up pressure.   Bubo Posted on Monday, June 29, 2009 - 09:31 pm:        i found the same as skntpig no po406 the filler neck could be pinched   Skntpig Posted on Monday, June 29, 2009 - 09:49 pm:        Pretty sweet. Diagnosed your truck problem in less than 1/2 hour on a motorcycle forum.   Ourdee Posted on Monday, June 29, 2009 - 09:51 pm:        P0406 EGR Position Sensor Volts Too High EGR position sensor input above the acceptable voltage range. I think.   Midknyte Posted on Monday, June 29, 2009 - 09:59 pm:        Control-Alt-Delete?   Ourdee Posted on Monday, June 29, 2009 - 09:59 pm:        http://www.asashop.org/autoinc/dec97/egr.htm
