You could ship yours up here and I could do a quick test.? PM me if you want to do this route...........

P.S. I'm changing the subject line to reflect Timing & ECU

   Hey Steve:

Thanks for taking the time to send me the email.? Actually, the car suddenly died on me 90 miles from home and had to be towed, which was the beginning of the discovery/learning process.

It appears that the only way to check the ECU is to plug it into another 91 Audi 200 20v to see if it starts.? I found a used ECU for sale at Shokan for $800 and another one at Force5 for $350.? Being laid-off and tight on cash, I can't just throw money at something to HOPE that is the problem.

That is why I am hoping I can plug my ECU into a functioning 20v to see if it works or not.? Any thoughts?

I really appreciate everyone's help with this.

Thanks,
Stan

 Stan-

One of the best pieces of advice I ever got was from a very experienced Alfa mechanic. I'd basically done the same relatively simple and supposedly low-impact changes you did, and suddenly the car wouldn't start.

I called him in a panic to try to get some debug steps, and the first thing he said was:

?"What did you do? The car used to run, so the most likely thing is something you did broke it. Go back and double/triple check everything you did, then call me back"

It turned out that the new distributor cap had the #1 cylinder marked in the wrong spot for no readily available reason, and I'd used that rather than the old cap & wires when I installed all the new stuff. Reorder the plug wires, varooom!

So, every time I mess up something, the first thing I always ask myself is "what did I do?"

I suspect your timing is out enough (combination of the T-belt and distributor work) that the engine isn't seeing a good signal from the hall sender in the distributor, and the ECU isn't triggering any spark.

Good luck, and don't get discouraged. The 200 20Vs are great cars, and relatively easy to work on.

 ?Is your ignition switch known to be good?

 Go to this site:
 audifans.com and sign up on the "quattro" & "200 20V" mail list.

 They know a bit more than I do.?
 I have an ECU in Gloucester MA, but some chipped yours and probably wrote their name/company on it to ID the ECU chip upgrade.

 Keep us informed.? 310:? LA?

  ? Hi:

 My name is Stan Evans and I have a 91 Audi 200 20v that I picked up last year.? This is my sixth Audi (3 different '90 200 Qs, 90 Coupe Q, 93 Audi CS Wagon) and now finally a 200 20v.

 First of all, THANK YOU so much for the valuable info on your site.? I was able to change the timing belts (it was off TDC), double check the distributor, replaced the original fuel pump, replaced the starter, and learning about the ECU.

 Here is the situation...the Audi is not producing any spark from the Ignition Coil.? I have ran the codes, ran the other basic checks from the combination of your site, Bentley's Manuals, and http://www.sjmautotechnik.com/ .? At one point I did get spark from the ignition.? A couple days went by and I tried again and then no spark.? UGH!? I ran some of the tests on the ignition and supposedly according to Bentley's the ignition coil was bad.? Simple replace and nothing.? !@$%^

 Anyway, I thought that before I spend money to see if it is the ECU, I could see if there are any local owners of 91 Audi 200 20v Q that I could quickly have us either plug my ECU into their car to see if it starts, or plug their's into my car.? The ECU in my car appears to have been accessed at some point.? There is no plastic baggy around it, and someone wrote a name on the underneath the ECU.

 So do you know of anyone local I could perform this quick and simple test with?? If not, could I send my ECU up to you and the other guys at Quattro123 to see if you can plug my ECU into one of your cars?

 I have been driving around in my clunker Jeep and I think the tranny is about to go in it.? I really appreciate your help with this.
