Default Re: resetting the computer????

Turn the key to "on", but not started. Pull the ECM-A and ECM-I fuses in the underhood fuse box. Put them both back in, at this point you should hear the fuel pump pressurize the fuel rails. Turn truck off - you are done.

Usually I turn my key to the run position, the pull the two fuses that I mentioned, let it sit for 5 minutes, turn the key off, re-insert fuses and start the truck. It seems to work for me that way.
