I have a 2003 dodge grand carvan. Last night when I left work(the van was outside)I let it warm up for 10 minutes while I scraped off ice from the windows. It ran fine all the way home (10 miles from work). When I tried to start it the next day all that would happen is the engine would turn but not start. I have left it in my garage and I have added a bottle of Heet to see if I have a gas line freeze problem. Nothing has been done to the engine so no cables or wires are loose that I can see.

Hello,

Just so cover the basics, have you tried to jump start the vehicle?
On cold mornings if the battery does not have enough cranking amp it might crank for a little but wont start the engine.

If you are unable to jump start it, but the engine is cranking over strong. Then you will have to check to see if you are getting fuel. If the fuel pressure is not adequate it will not start the engine.
The fuel pressure regulator could be at fault if you are not getting enough fuel (given that the pump is coming on). Many times cold temperature can impact the regulator performance.
You should have 58 PSI of fuel pressure with the key on and engine off.

Please let me know of any questions.
Thank you.
