I have a 2001 Chevy Tahoe, 5.3l. Lately I have had a problem with it not wanting to start. I will shut it off and then go to start it again and all it will do is crank. I replaced my fuel pump less than a year ago with a Delphi from the dealer. Sometimes if you let the truck sit for a few hours, it would fire right up no problems and would run fine. Today, it just will not fire up. What problems have these had with the Passlock security system?
