Stopped for gas, removed key from ignition and alarm went off. I assumed I accidentally hit the panic button on the remote so used the remote to silence alarm. After filling up car would crank but would not start. Tried turning key to on and could hear the fuel pump running. Opened trunk to see if I had a flashlight. Popped hood, reseated coil wire. Thought about what tow company to call for a few minutes. Tried again and it started right up and ran fine. As it is a 2001 Cabrio, can the immobilizer let it crank but not start? It reminds me of an old problem with an MG called a vapor lock. But I don't think vapor locks are problems any more. I'm glad it started, but without finding the cause means it could happen again without warning. Any ideas? It would almost be better if it did not start so I could find the problem.
