Have tried to pull error codes after this occurs, and get a "No Link" error. When vehicle is running, no error codes are detected, and check engine light is off. Shutting the truck off and disconnecting the battery for several minutes does not clear the issue. Truck will start again after random amount of time, but ignition has to be turned off. After the "No Bus" Error appears, starter will spin up, everything moves like it's supposed to, but engine will not fire up.
Have read several threads with similar issues, and most of them point to a bad ECM (read expensive problem), or a bad ground in the system causing the ECM to freak out. (Read hard to find problem).
My question is, how do I go about determining which of the two sources it is? I'm not the most mechanically inclined person, so talk to me like I don't know anything, you'd probably be right.
I know how to use a multimeter, I just have no clue where to start looking on a vehicle.
Help? Please? :D
have the same problem?
