Customer Question

Customer: car crank but no starter some times
JA: Thanks. Can you give me any more details about your issue?
Customer: the car runs somtimes, but other times it just cranks. i put a new crankshaft sensor and two camshaft recently. seems to be doing the same thing, troubleshooting doesn't give me any code. it also has anew fuel pump and filter. computer doesn't take any code. the only code that came up was for the camshaft sensor which is why i replaced them. like said it runs sometimes and other times it just cranks
JA: OK got it. Last thing — JustAnswer charges a fee (generally around $18) to post your type of question to BMW Experts (you only pay if satisfied). There are a couple customers ahead of you. We can help you for less if you're not in a rush. Are you willing to wait a bit?
Customer: yes I can wait
JA: OK. Now I'm going to take you to a page to place a secure deposit with JustAnswer. Don't worry, this chat is saved. After that, we will finish helping you.
