Q: Car only starts sometimes; problem with PCM computer

Car only starts sometimes; problem with PCM computer.

If the PCM has a problem, just about everything on the vehicle can be affected. I would have your vehicle inspected by a qualified engine technician in order to diagnose your starting issue and your PCM. It may be possible to simply add some updates or reprogram the PCM to fix this issue. If not, the only way to fix the issue would be to replace the PCM. Unfortunately the PCM is a very expensive part on most vehicles. With this in mind, be sure to have it replaced by a technician with good credentials in order to save money in the long run.
