2002 Chevrolet Avalanche 2500 Q&A
2002 Chevrolet Avalanche 2500 Question: loading up with fuel. Fuel pressure reg??
When the truck is warmed up and the weather is HOT outside, it seems to load up with fuel. it pops and "backfires" when accelrating until it "cleans itself up" then will run fine until idling again then it starts all over again. NOW when the weather is a little cooler outside it doesnt seem to do it as much. I was told I should take a look at the Fuel pressure regulator. Does this sound like it may be the problem?? and if so, is there any way to check it?? THANKS!!! - rtrickert
Any codes? 8.1L engine right? Scanner with live data is a must here. Cold eng. CTS reading = ambient temp.? - pushrod
possibly a 8.1L since its a 3/4 ton trk.ck fuel pressure it should be 56/62 lbs if you have more than that suspect regulator - globalhelper
