My 2000 V70R has not been starting very well recently. It runs fine, it just takes a while to actually get started. I just changed the plugs, kinda seems to me like it's taking longer for fuel to get into the engine and that's why it wont start. Does it have multiple fuel pumps or something? Thoughts on what this could be?<p>My second question, the driver's side rear end if sagging, it always sits lower than the passenger side. Is my nivomat done or could this be something else? Rather not have to pay for new nivos if I can avoid it. Thanks

Your fuel pump check valve is probably toast (common 2000 issue for some reason)! <IMG NAME="icon" SRC="http://www.vwvortex.com/zeroforum_graphics/screwy.gif" BORDER="0"> <br><U>If it runs fine after it finally starts,</U> 99 out of 100 that's your problem.<p>Dealer or indie mechanic will probably want to sell you a $750 fuel pump, I have an aftermarket check valve that works just fine.<br>Been on my car for two and a half years now with no issues! <IMG NAME="icon" SRC="http://********************/smile/emthup.gif" BORDER="0"> <br>If it's determined that that's your problem, <B>you can have one for $85 shipped.</B><p>As for your rear sagging it's probably the Nivos, MAYBE a spring, but doubtful

Check battery voltage? That's my first suspicion on <i>any</i> car. After that, then I'd go with the odder things which Jim <b>better</b> know about by now! <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/eek.gif" BORDER="0"> <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/biggrin.gif" BORDER="0">

It's the check valve, bet my rep on it

Re: Engine and Suspension Question (magnato1)

I agree 100% with JRL, especially since been through it myself. Buy or rent a fuel pressure guage, screw it onto the fitting at the end of the fuel rail. You should have 80lbs of running pressure, and when you turn the car off, you should hold between 30 and 40lbs. for a couple of hours. It's refered to as "the stay pressure". I myself installed a fuel safe check valve, but my warranty covered the pump so I changed it. I still have the check valve I think. Anyway, if you have a good stay pressure, maybe cam position sensor, or cam reset valve? Just check the pressure at the rail, it takes minuets to do. <IMG NAME="icon" SRC="http://********************/smile/emthup.gif" BORDER="0"> good luck

good advice to check the stay pressure.<p>for what it's worth, my XC's occasional long crank problem was cured by a new camshaft position sensor. my check valve was fine.<br>

Re: (db130)

K, great. Sorry I'm just reading this, been really busy. I will check the fuel rail and go from there. Thanks guys. Hopefully it is just an $85 dollar fix.
