ECU Not grounding fuel pump relay
Well I'm back at it again with the first bike/project bike questions :P
Spent most of today trying to figure out why the fuel pump won't prime. After going through all of our testing we narrowed it down to the ECU not grounding out the relay so the pump isn't priming. All of the other relays work just fine, and using a jumper wire on the fuel cut relay will get the pump to run.
So here's my question for all you veteran two wheeler folk. Is there anything else I should check before assuming its just my ECU, like the ground box by the battery, or something I just haven't thought of? If not, do most dealers have a way of testing an ECU before I go dump money into replacing it? (Seeing as I have to save up for that frame rip). Sorry for all the questions after just starting my account, but I got to learn some how :D
