[gabel@acmepower.com (Glen Abel)]

     Ok, I have been tearing my hair out over this, but Im sure you are all 
     familiar with the hot start problem I have been having through 
     previous posts... If you dont then read the next paragraph if you are 
     skip it and goto the results:
     
     PROBLEM;
     
          Would NOT start hot... not a peep just keep crankin' the car 
     didn't want anything to do with starting. Went to the AUDI Dealership 
     and was buying a temp sensor and asked the parts manager "Who is your 
     best Audi Mech.?" and he pointed to a guy and I talked to him. Told 
     him my problem and before I could get the words out of my mouth he 
     told me EXACTLY what my symptoms were.. "Let me guess he said, you go 
     into a store to get a cup of coffee and come out and it wont start or 
     starts crappy?" YUP That was it, "You needs injectors" he said.  He 
     seemed SO confident by this that I ordered new ones, and after I put 
     them in if anything It made it worse. Now it wont even sputter when 
     cranked...  I called this YO YO at the garage and said, "Dude I just 
     spent $180.00 (good price though, thanks to a fellow lister) and It 
     still wont start. all he had to say was "You have a vacuum leak" I 
     told him no way of the vast assortment of Snap-On and MAC Tools I have 
     I did have a vacuum Gauge. He had no other alternatives to look at. 
     
     
     
     SOLUTION; 
     
           I wrote a few e-mails, planned my trips carefully so that when I 
     needed my car it would be stone-cold, carried a screwdriver and a can 
     of either with me (just in case, I could force start it this way) and 
     Purchased the Bosch fuel injection handbook. BTW This book is good I 
     would recommend it, even if you don't have a problem its good to know 
     how things work. An e-mail came from a fellow lister Brett Augsburger, 
     and he went into alot of theory about fuel, and vapor lock. His 
     thinking was that the check valve was bad and the fuel next to the 
     injectors was turning to vapor. At first I was skeptical I must say 
     but the more and more I thought about it it made sense, I was in my 
     barn and took an old injector and threaded it into my blow gun, It 
     opened fine? What was wrong the thinking there was that the air 
     trapped behind the injectors was NOT compressed yet and when the fuel 
     pump turns on there is enough un-compressed air there to hold back 
     fuel.... (I should have known with A fine German name like Augsburger 
     he knew what he was talking about)  Anyway, went to the dealer last 
     night saw my mechanic buddy told him I was buying a check valve, he 
     still insisted that it wasn't. I told him "There's the car, go start 
     it then smart guy... Of course it would not start... after a few min 
     of poking around he said "Let me know if that fixes it"  Well I got 
     the car in the barn and changed the check valve, adjusted a ABS 
     sensor, (I put a spring in and a wheel bearing this weekend) and was 
     on my way, warmed the car up ... waited about 4min and BAM!!! IT 
     STARTED!!!!!!!     PROBLEM SOLVED ..CHECK VALVE>>>> CHECK 
     VALVE......CHECK VALVE........ IM GONNA MOUNT THIS P.O.S. ON THE WALL. 
     IT KICKED MY BUTT FOR 2 WEEKS.......
