"Red"do the early aveos have fuel pressure sensors? mines a 2004 model and in my live data stream I have a fuel rail pressure listed and its constantly 0psi. I have a rough idle as stated in my other thread but it drives fine.

anybody know?
I'm no expert, but I want to say yes. From what I understand fuel pressure has to be regulated for the injectors to work properly. Even though it drives fine, but idles rough there could still be a problem. It could be too high from not being regulated properly, and simply evens out when driving. I have an 2005 and would be happy to check the fuel pressure, but I don't have a code scanner with live data.
From what I understand, if it didn't have fuel pressure it shouldn't even idle/run. Or if it does, it would studder and die as soon as you tried to rev the engine.
Just my two cents.

thanks man. looks like I need a fuel pump. I'm guessing that's where the sensor is. can get a used one for 57 bucks
definitely thinking fuel pump now. the reading is always zero. got plenty of pressure. exhaust smells of gas , bad misfire at idle and long term fuel trims near -20 at idle. plugs are clean but I'm thinking that it's so rich that its washing them clean. also, bad MPG. it must think that the pressure really is 0 and is trying to compensate and can't compensate enough.
anyone else want to weigh in?

Sounds good, hopefully that's the only issue. I was also hoping someone else would "chime-in" and either correct me, or back me up. :/

I honestly don't know what else it could be. the at idle load percentage is 40- some percent. the tps signal is 14.5 percent at idle. im thinking most of the problem is the fuel pressure sensor though. I don't know what else it could be.Originally Posted by AndrewButler05

well it wasnt the pump...
in the shop now. guess we'll see.
Hopefully they'll find out what it is soon. I think people aren't that active on this forum anymore. I'm surprised that no one has replied here...well it wasnt the pump...

This forum has indeed been inactive, with very few regular contributors. BUT it's a 2-way street. The OP had a prior thread going on this exact same problem. In that thread I had suggested that he do some testing (including a fuel pressure test with a gauge) prior to installing parts. He didn't respond to my post, and chose instead to abandon that thread and start a completely new one on the same problem. So there is no way I'm going to waste my time trying to talk to someone who clearly showed he isn't interested in what I have to say.
