Hi ~ 

My hubby says he has more info to add:   He checked distributor and hall sender.   He can see spark when he turned the engine over ... but he didn't check every cylinder yet.

Checked all hoses around air sensor and replaced the ones that looked warn.

Tried cranking car to read codes and it will not transmit the codes, except to say that there is no codes stores in memory.   :-(    .... So I supppose that is the same thing that a mechanic would get, right?

More background:

The car was running poorly while he couldn't get O2 sensor out, like rough idle whether warm or cold, and it idled too fast also     He drove a couple hundred yeards from the house, and then no power, it wouldn't go higher than an idle.  It felt to him like "the throttle linkeage has disappeared."   Then it died and was hard to start.    After he got it in the garage it wouldn't start at all.

It sounds to me like a fuel related problem--are there any electrical parts/sensors which would cut off the fuel.  He said he had checked the fuel well past the filters and such and said there it was pumping.

But after all of the work he did changing all those thing he didn't actually *look* to see whether the timing belt had broken, so he is down there right now doing that.  

Any other suggestions?   thanks ~  Cat

>My hubby has been trying to get the 02 sensor out of the 87 Audi 5000 Automatic, Non-Q, Non-Turbo.
>It finally just started to die on Friday.   He could drive it home with almost no power and it now won't run at all.
>Tough to do the diagnostics without the engine running eh?
>He says it has spark and says it has fuel.   He says it turns over (he did put the 02 sensor in), and he even tried moving the entire air flow sensor and fuel distributor from the 88 Audi 5000.
>He missed two days of work working on it, and we hate to tow it somewhere, (like the stealership) if we have no clue at all what might be wrong.    We had started to strip the 88 before to junk it so that won't run now.....
>He checked the coil, he didn't find any vacuum leaks, but I don't know one could find them without the car running.
>He replaced some hoses just to be sure.  
>He swapped the electronic control and the ignition control units.   
>He checked fuel potentiameter.
>Poor guy has been laying on the cold cement for three days and it still won't start.    It took a huge amount of time to drill and tap the exhaust manifold because the bolts broke off and found broken motor mounts in the rear and had to replace those.      We are down to one car apiece with little funds, so this is getting serious.
>Any suggestions would be much appreciated.  Thanks !!!!!!!!!!!
