I had this same problem once. Turned out to be the distributor/rotor. The distribtor seal wore out and slowly leaked small amounts of hot oil into the distributor while the engine would run. Eventually, it melted/dissolved some of the softer components inside and actually slightly warped my rotor.
Same type of thing happened. One day it was running great, then the next min, dead as a doornail. Replaced the dist and rotor, problems solved. On the topic of your timing belt, as said, take off the upper timing belt cover. If you dont see a belt wrapped around the pulley, theres a good chance it broke. How many miles do you have on the car? have you ever had the timing belt replaced before? ----- Original Message ----- From: "Jack Simon" <[email protected]> To: <[email protected]> Sent: Friday, August 05, 2005 7:29 AM Subject: Re: [a2-16v-list] Backfire then Dead > Larry, > > Take off the top cover for the timing belt (couple screws or > clips) and have a look.
