1994 Impreza runs then cuts off

[Tinydancer10]

I have a 1994 impreza that runs great and then it cuts off, it might run 5 mins or an hour and then cuts off. Any ideas

gonna need a bit more info. when it dies does it restart? if it doesnt restart you should see if its no spark or fuel. also is there any codes on your ecu?

yeah some info is needed. two things to start with Fuel and Spark. Fuel pump and Coil pack (I'm not saying go buy new ones and replace) those two contribute to fuel/spark and both of them will get hot and stop functioning when they start to fail.

 

Next time it dies, pull a spark plug wire off the coil pack and position it back a 1/4" from the edge of the terminal and having someone crank the engine over.

 

Fuel side, pull off your fuel inlet line (with the key off and watch out for fuel spraying back at you when you pull the line off) with the line off, hold the hose over a container (I usually use a 20oz pop bottle) and have someone turn the key on. Fuel should run out fairly fast as soon as the key is turned to the on position.

 

 

Thats something to start with
