JA: Sometimes things that you think will be really complicated end up being easy to fix with Mercedes. The Mercedes Mechanic I'm going to connect you with knows all the tricks and shortcuts. Tell me a bit more about what's going on so he can help you best.
Customer: Low voltage at the fuel pump relay. about 8 volts. not enough to trip the relay to energize the pump. Any ideas?
JA: There are so many things that can cause battery
issues. Some simple, some complicated. The mechanics have tons of experience in that area. Will the car start?
JA: Glad to hear that. How old is the battery?
Customer: I don't know. It has 12.5 volts when the car is not running and high 13 when running
JA: Are you hoping to fix this yourself?
JA: Great! What have you tried so far?
Customer: nothing other than trying to figure why the fuel pump wont start by measuring voltages
JA: Anything else I can tell the Mercedes Mechanic before I connect you two?
Customer: low voltage at the fuel pump relay. around 8 volts.
JA: I'm sending you to a secure page on JustAnswer so you can place the $5 fully refundable deposit now. While you're filling out that form, I'll tell the Mercedes Mechanic about your situation and connect you two.
