The car in question is a 2003 BA Turbo Auto. These were minor at first, however it is now turning into rough idle and loss of power and then the engine stalls. When I attempt to restart I turn the key to start and the car does not turn over. Battery voltage while car is running is 14.4V. No Fault codes on a scanner and I have traced the wiring from fuel relay to starter with no issues. That's the history anyways. What are my options in regards to trying not spend a huge amount of cash on this? Buying the car a year ago I spent a considerable sum on performance mods on the car after purchase and really don't want to through another huge amount of cash into it. Also trying to sell a car that has computer issues and not really running would also cause a hefty loss. My only real thought at this point of time is get a remanufactured PCM for just under 3k and purchase a PCM license and reader to pull the tunes off of my PCM and put onto the new PCM. If anyone has better ideas, please do tell. Cheers All Link to comment Share on other sites More sharing options...

For the problem you are having, I think you need to work out exactly where the problem lies, so you know that what you do will help. $3k for a PCM without being 100% sure it will fix the issue is a lot! The "rough idle/loss of power/stall" sounds like it might be a different issue to "I turn the key to start and the car does not turn over". "I turn the key to start and the car does not turn over" sounds like it might be a starter motor, or battery failing? If you think heat causes the problem, does cooling the PCM make any difference? What happens if you start the car with the bonnet open and let the engine get to operating temperature - I think the PCM should not get too hot then? Does the problem still occur? Have you ruled out problems with spark plug coils or fuel pressure? Where are you located? Link to comment Share on other sites More sharing options...
