'90 Turbo 200 -> REAL hard to start ?

But once it starts all's well. Even after it finally gets started [maybe 5 secs of crank time] it takes an equal time to finally get up to normal idle rpms. Sometimes a puff of white smoke is emitted out the exhaust on
startup too.
The oil pressure, temp and alternator gauges all show OK and the battery's new.
The car has about 350K miles on it but other than the hard starting runs great.
It's been recently tuned-up with no improvement.
What's wrong and how can it be cured ?
Appreciatively, Courtney Thomas

There are a number of threads about things like this on the Audiworld T44 forum: http://forums.audiworld.com/v8 /
A few things to suspect: - Dirty injectors - Run a bottle of Techron injector cleaner in a tank of gas. - Failed pressure check valve on the fuel pump - replace pump - Fuel filter needs replacing

Try replacing the temperature switch, it may be giving a false signal to the ECU

did the tune up adjust the co level? the co has a major part in starting the car , i have adjusted the co on a few 200s with quicker starting as a result, it is most likely adjusting slightly will help, if it doesnt turn the opposite direction be sure not to adjust it too much and do it with the car running so you dont have no starting at all, www.audicd.pwp.blueyonder.co.uk

Courtney, Check out the troubleshooting info at Scott Mockry's web site: www.sjmautotechnik.com Try pulling the fault codes and see if anything turns up there. If the car sits unused for a couple days, does the hard starting go away? (fuel pressure leakdown likely) On a different tack ;-) how did Mutiny fare during Frances? Cheers!

Steve,
Thanks for asking. Mutiny's fine, being on the hard in coastal NC, including tarped & strapped down.
As for the Audi, sitting up for a few days doesn't affect it's current malady. The mechanic says that since it intermittently emits white smoke on startup it may be a head gasket or crack between cylinder walls, since the smoke is possibly anti-freeze.
Thanks again for your response.
Cordially, Courtney

Courtney, Good to hear about Mutiny - the news coverages of damages from those storms seemed to always include footage of piles of boats. To see if the smoke is antifreeze, a simple test is to get a glass jar, and hold the open mouth of the jar behind the tailpipe until you get a good quantity of condensation in the jar. Put the jar in the freezer. If the liquid in the jar has not frozen by the next day, it's antifreeze. A compression/leakdown test will show you if there's any leakage in the cylinders - also, if you hold an inspection mirror over the spark plug holes of a warm engine, if there's an a/f leak into a cylinder apparently it will show up as fogging on the mirror.
