What fuses should I check? I have pulled some already with no luck.I have a Jet performance programmer.Every time I plug it in to the vehicle it says-No communication check key is on.I don't know what the check key pertains too.I want to install the aftermarket performance program from jet but I keep geting the check key.I had a program installed from the same manufacturer after some checks they gave me a new one(programmer) and said to have the dealer return the ecm to the factory settings & then try to install the new program.Now same problem as before.
