Hoping somebody can help with my BF130 that will turnover but will not start?
I was about to take my boat to the marina last week so decided to start theengine before the road trip just in case, lucky I did as it wouldn't start, itjust turns over.
I checked the plugs for a spark and they were fine so thought it must be afuel problem. I started with the low pressure pump and this had fuel soI moved onto the vapor separator which also had fuel. I then loosened thefuel pressure check nut half expecting to get covered in fuelbut nothing more than a dribble came out.
I managed to find some tests to do from a service manual which involved testingthe main relay however this seemed to be ok so I then moved on to test thevoltage supply from the relay to the pump and this was showing only 0.04 voltswhen I turned the ignition on.
I then went on to the supply the pump directly with 12V from a battery and itworked fine, it even gave me a nice wash in petrol where I hadn't tightened upthe fuel check nut properly...
Assuming the main relay was actually faulty I ordered a replacement which cametoday. (PN# 38580-WZ5-004 ordered. Received PN# 38580-WZ5-014) however afterfitting it the engine still only turns over and doesn't start.
Looking online and in the manual it looks like the next test is to swap the ECUbut my marina doesn't have 1 to test with and I am reluctant to order onestraight away as its going to cost just under £800
Does anybody have any suggestions or further tests I can do? I really don'twant to have to find £800 to throw at this only to find I didn't need to.
Thanks.
