This vehicle has no ignition coil drive to cylinders 1-4, no related fault codes (just a P0103), flatline at the PCM output. Will it need to go on IDS to program a new Siemens PCM? I have ACR4 and Texa but don't know if either of those is up to the job. Will give ATP a ring in the morning to see if they can do a repair before buying a new one. Any advice is welcomed.
