My airdog makes a running noise when my key is in wait to start mode, but thats it maybe like a second or two
. fuel pressure is about 15 in idle and 12 at WOT. and when its cold its at about 13? i dont think my airdog is working? it doesnt make any noise when the truck is on. any clues?!!?

 

It wont continuously run at key on. Should have a short prime at key on and if you bump the starter after key on it should run for a little while. Your pressure readings look like the pump is working fine.

 

oh okay! sweet. i wasnt sure. thanks!
