On the road, truck will not start since the lights were left on.

I'm in a jam. I left the lights on truck will not start. This happened once already.

I'm afraid that if I call my job again to assist with this I will get fired. However, I don't have enough cash to pay for it. What can I do? Is there a possibility that if I let the 18 wheeler just sit it will be able to start 8 hours later.
