No White smoke. The other person said it might be the fuel accumulator but I thought that was for hot starting. If it's for cold starting also after sitting is there a way to check ie: with a vacuum pump, should it hold pressure. Also I had a VW rabbit that was hard to start all the time and it turned out to be low pressure from a bad fuel pump. Could this be the problem or not since mine only happens after sitting for a few days and not all the time. Does anyone know what the line pressure should be when running. Thank You again for Responding Roger
