yes, did he ever give you a a delivery date or time frame, like 2-4 weeks for delivery. if so and it has been past that timeframe you have like 60 or 90 days from the promised delivery date, to start a dispute. call your credit card company and tell them you need to dispute the charge from him. tell them he told you it would be delivered by ( insert date), even if he didn't give an exact date your credit card company will want a date so figure out when the order was placed and add the shipping time. tell them you have already tried to settle the problem with the merchant but you are being told that he won't ship the items because he doesn't have an account setup with the supplier, so basically he sold you merchandise that he had no access to, but he refuses to give a refund eventhough he doesn't know when he can get the items.

your credit card company may want you to write a letter to them explaining what has happened, if so pm me and i can let you know what info you should make sure is included. once the dispute is started they will contact the merchant and he will have to show proof that the merchandise was delivered to you, he can't, so you would end up winning the dispute because he failed to deliver the merchandise by the promised delivery date. make sure you tell the credit card company that he does not know when he will be able to ship out the items and you can't wait, since it is car parts.
