I am trying to find out which fuse to pull in the fuse box under the dash to reset the ECU....is it the fuse marked "eng cont" ?,

and also if this it, how long must it be pulled to reset the ecu?

 

Why do you want to "reset" the ECU? You can reset teh ECU manually if you're getting a code by using a flathead screwdriver and following the steps in the FAQ.

 

I was getting pinging and have been using 93 octane all along,,,I wanted to clear the ecu, not just the codes, "there were not any codes", so the ecu would have to relearn,,anyway I pulled the fuse marked eng cont and left it out for 1/2 hour and the car has not pinged for the last 200 miles. want to know if anybody has any input about this?

The car would not crank with this fuse pulled, and I think that this is the right fuse that kills power to the ecu???? anyway its not pinging anymore!

 

Well, were you getting codes? If so which codes were they? What you did was basically just resetting the ECU with teh flathead screwdriver (turning the screw on teh side). It starts out like brand new and relears everything. If you have a problem, it will come back.

 

I pulled the fuse...it stopped pinging
