: audi 80 b3 89 1.9 wont run more than 30 sec

got an audi B3 1.9 that starts then stops after about 30 seconds. also when you open the throttle it basically stalls.

there is a metal device attached to the air duct that buzzes 3 seconds, 1 sec off then 3 sec again. ?
also, i noticed the air filter is damp with fuel.

any ideas.

are plugs wet with fuel ? if so, bad inj ? stuck in cold start mode ? stuck pressure regulator ?

i picked this car up a week or 2 ago, 2nd hand.

ok some more info, their was a fuse on the top of the fuel pump relay, took that out (found out its a test mode)

It can now run for a longer period of time at least 5 minutes so far, but is rough, if throttle is held around 1.5 krpm it will stay running, but quick revving or holding the throttle flat the engine stops . let it ldle its sounds bit camy then stops. ?
