Installed a known good CPS crank position sensor. During it's few days with a used ,known good distributor, with the customer, it failed to start after sitting 2 hours. So I removed the distributor and installed a Crank sensor. So far it's not come back, and all the tests I ran on a digital scope and a Vantage, never saw any problem on the wave forms...However I did buy a amplifier/coil assembly from METRO VW in Dallas $140 ish'. So far don't seem to need it...Any one need a coil? BTW, That Bentley Book company says you can buy the coil or the amplifier on their own......NOT !!!! (Complete assemly # 6NO-905-104.) Later folks, gotta see if'n I can go catch up on the rest of my work....Don. PS....Belated thanx to all who took time to send e-mails, I think I replied to everyone, but if I missed you, Thankyou, every little helps...DK. _____________________ ORIGINAL MESSAGE _____________________ Just when I thought I was getting the hang of this mechaniching game, here comes a curve ball ! Will occasionally, especially when it's with the customer, will crank fast but not start. ECU logged a code PO322 and so I cranked and started it a dozen times and it starts every time, mmmmmmmm. Visual ck inside the NEW dizzy cap and rotor from last visit (for a miss on No 1 cylinder.)found no problems. Last visit turned out to be a faulty plug cap. When running, customer complains of brief loss of power. Primary problem is first thing in the morning cold crank, no start Scoped the CMP and the CKP with the Vantage and also watched other parameters on the Retreiver.] There is zero ( 0%) adaption for fuel or ignition by the adaptive program in the ECU. Runs strong on the highway and rev's to cut out under load with no glitches. Besides performing perfectly for me, this is not right. E-Mail achives list 428 posts for the word..START, and I think that vanagons take the lead for the worst,in posts about that ! Now, if any of you fine people out there know anything, don't keep it to yourself. Tomorrow morning I shall test for start up again but I think that it's gonna be a crank and fire like nothing's wrong..... So, what you all think...?? Crank sensor or distributor ?
