I will go out before I go to bed and run it for a few seconds to refill all the lines. I am starting to think it most likely is a fuel vaporization problem since I drove round town for about 45 min then parked the car for about 3ish hours and I had the same symptoms that I have in the morning. Also, I tried turning the key on and off 1st and that made the problem a little better b4 starting, but it was still there. The fuel system is holding the pressure since I have a fuel pressure guage permanently mounted and it reads 29 psi even an hour or two later. I will check in the morning too to see if it still has held the pressure overnight. Just keep coming with the suggestions. I thank everyone for such great suggestions. Hope I can get it fixed :) I thought of one idea...if it is fuel vaporation, could I put high temp fuel line heat sheaths over the lines to try to deflect the heat. Would this be worth a try? As for air leaks, where should I check and how, since I put all new lines and I spot checked every clamp for leaks for a while after getting everything together and running.

The pump will run any time the engine turns over; it knows when this is happening because the trigger points in the distributor are opening and closing. In addition, the pump will run for ~1 sec after turnon even if the starter wires are disconected and the engine isn't turning over. If all the FI wires are removed from the starter, the system works just fine unless things get really cold, which I don't think applies here (he's in Chicago, I'm about 100 miles north of him.) This probably IS a problem with the fuel system being full of air after cooling down, but the cause of this will have nothing to do with the CSV wiring. It is most likely that the heat soak after shutdown is causing his gas to boil and that subsequent cooling down draws in air which is there the next time he tries to start the engine. In reality we don't have enough facts yet to make a certain diagnosis, but there is a simple test that is useful: Charles, drive your car normally and park it for the night in such a way that you are pretty sure that it will be hard to start the next morning. Let the engine cool off completely then go out and start the engine just before you go to bed. Presumably it will be hard to start. Once it starts, let it run just long enough to smooth out (30 seconds should be enough) and shut it off. You DON'T want the engine to warm up. What you have done is to refill all the fuel lines without getting anything hot. The next morning the lines should all still be full and if my guess is correct the car will be easy to start. In that case, you need to look for and correct small fuel leaks that will also admit air as the engine cools. In the absence of finding the leaks, Charles can simply turn the key ON and OFF several times before trying to start and this will help fill the fuel loop with gasoline. These leaks can be anywhere and can be impossible to find; on my 72 I eventually gave up and installed a switch under the dash to allow me to run the pump and clear the system of air before trying to start. While this works beautifully, it is a bit of a pain and annoying not to be able to get at the root of the problem. If I'm wrong and the car still starts hard the next morning then he knows one thing that is NOT his problem and can move on to the next question. At current temps in the midwest, however, this still won't have anything to do with the CSV. If your problem continues, I'm really rather close to you and the weather is getting nice enough that a drive to WI might make a nice diversion. ;-) - Jim Adney jadney@vwtype3.org Madison, WI 53711-3054 USA ------------------------------------------------------------------- List info at http://www.vwtype3.org/list or mailto:help@vwtype3.org
