Hi! My boss lent me her 2004 Montana. A couple weeks ago the thermostat needed changed and I did that. The other day it was running better than ever and all of a sudden it won't start. It does crank and it sounds like a fuel issue, but the pump was replaced a year ago. Her daughter, a regular driver of it, says it's done this before but after 45 minutes it goes ahead and starts. It did this, just as she said. I drove home and now it's been 2 days of cranking but no sign of starting. Put a code reader on it and nothing about the fuel pump comes up although a fuel pressure sensor warning did come up. Would that be the issue in itself? The fuel filter was changed at the same time and as far as I know it's never ran out of gas. Thanks everyone!
