2007 Bf150 issue. No start with a twist

Hi all. Been several years with out a boat. New to me Bf150. Squeeze bulb
Till hard. 2 beeps when I turn key. Crank good but no start. Small squirt of start fluid and she fires immediately. Runs perfect for a few seconds then dies. I hear no hum like from a fuel pump. Fuse? Circuit breaker? Or worse? I did a search but nothing exactly like mine popped up. Thanks for any ideas. Ed
 
Hi,
I don't have any experience with that particular outboard nor do I have any service information for it.
You don't say if it is an A model or a D model and I don't know the difference between the two. It might be useful to someone else trying to help you though if you could post that info.

Just wanted to say that, since it starts and runs on artificial fuel (I caution about using ether) it would definitely seem to be a fuel starvation problem if it has been in storage with old fuel in the VST tank and the fuel lines, that might be at least partially of the issue.

I agree with you about checking fuses and there is also a fuel pump relay. See item 5 in link below


You might be able to remove the fuse box cover and touch the relay when cycling the key to ON to feet it click as the points inside close. The computer should power it for about 3 seconds or so at key on to prime the electric pump. It should then turn off but then energize again as the engine begins turning during cranking. If the relay clicks as expected, the fuel pump is likely being supplied with power and you will then need to investigate why it may not be providing fuel to the engine.

Wish I had more info to give you but maybe a little digging will get you going. If it sat with fuel in the lines and VST then you may need to do some clean up in those areas. A chore for sure but doable.

Good luck.
 
Thanks for the reply. Very helpful. I’m sure it is a 150A serial#. Banj -1301235 so newer than 06. I think I will check relays and fuses first. Quite a few years since I fooled around with VST. I’ll try the easy stuff first. Thanks again. Ed
 
Yes, you're right. The D models for 2007 serial starts with BBUJ 1000101 and up.

The example parts page I sent was for a 2007 A model with the serial in the BANJ 1300001 to 1300999 range. A match for your outboard.
 
Reading some more on here I went back and pulled the 10am fuse. It looked fine but switched it with the spare anyway. No difference. No hum or any sound coming out of the pump area. 2 beeps 2 red lights then one red goes off after a second or 2. I tried releasing the gear lever and tried 1/4 way. 1/2 way and 3/4 way. No bueno. Next move is to loosen lower cowling and check the hi pressure pump direct. Got the block # beanj- 1014907. Thanks for any ideas. Ed
 
Not knowing how long it sat before you bought it is definitely a disadvantage unless you can call the previous owner and maybe get some history there.

If it was "put up wet" and there was fuel deterioration or, maybe worse, there was some water in the fuel, the pump could be frozen.

Your plan for checking voltage at the pump is a good one IMO.
If there's voltage there at key on, then it's likely that the pump is locked up.

If no voltage, then checking at the pump relay might be the next move.
I don't know what operates the pump relay but I think that it might be the MAIN RELAY, item 18 in the link below:


You would then be in an area where the shop manual and wiring diagram would be a great help in figuring this out.

Good luck.
 
Thank you. Assume (🙃) if the main relay was faulty more than just the pump wouldn’t work. I’ll be back when I know more. Ed
 
Get the Honda shop manual if you decide you need a manual, the generics like Seloc are too generic for the Hondas.
 
Back in 1987, I stayed a night in Needles, California, the hotel turned out to be a dump. We should have booked Laughlin.

Drove from Phoenix, Grand Canyon, Palm Springs, San Diego, LA, pacific coast highway to SAN Francisco, then flew home to Halifax. $35 a night in a new hotel near Disneyland, $20 a day, unlimited mileage, for a new full size Cadillac.

Laughlin is still a nice place. We actually stay in Topock Az for the winters (30 miles south of Laughlin) then return to silver springs Nv in the summer. Not sure how many years we will be able to do it but for now. it’s a bit different life style. Ed
 
Ha ha.
The crappy Needles (got heat stroke there in 1990) hotel wouldn't let you eat a PB&J sandwich in the parking lot for $35 today!

One of the strangest things I noticed. 5-8 stations in needles Ca $7. Gallon diesel. Cross the bridge into ft Mohave Az and diesel 3.50. We are over $5 on diesel now so needles must be $9-10
 
back with ? I tested the 10amp mini fuse and got 12.3 volts. Then pulled apart the connection plug to the high pressure pump. Tested the hot lead and got only 3.1 volts. I’m starting to think maybe relay? Thank for any ideas. Ed
 
Just make sure that you select a GOOD ground when checking volts or it can fool you.

If it IS low voltage, then yes, it could be the relay. Is the relay right next to it in that box the same? If so, maybe you can substitute that one to see if the volts come up. That doesn't always work but sometimes it's a quick shortcut for troubleshooting.
 
Those two relays are different part numbers. So, don't try to run the pump with the other one. But you might still be able to just see if the voltage comes up. If not, it could be wiring or....again....the main relay.

A wiring diagram would really help.

NSDON is right, stay away from Seloc, Haynes, Clymer etc...

Hi all,, again. I took a fully charged 12volt battery and wired up test leads. Took the connector apart right at the HP pump and connected directly to the pump plug. Aggressive spark but no pump noise. Swapped +- and same thing. Then I loosened the test plug. Was wet but no pressure. Hooked wires up again and same thing. Next move will be to research VST removal to put in new hp pump. I’m still not sure why I only had 3 volts at the wire coming from the fuse box.
 
Well, it's clear that you've identified a bad pump.

Again I would re-check the voltage from the fuse box making absolutely sure of your meter connections and that you're using a good ground. A jumper wire connected directly to the battery negative post is often good for doing that.
I've been burned more than once due to poor meter connections when doing voltage checks. That would also include less than excellent conditon test leads.

Sounds like you're on the trail to getting her back out on the water. 🔧 :cool:🍻

Valid point on the ground. I’m going to concentrate on the pump replacement which might fix everything and if not I’ll address the 3 volt issue. Thanks again. Ed
 
I don't envy the $365 (boats.net)+ shipping and tax outlay for that little DC motor!

But, in case you don't already know, lots of people trying to substitute aftermarket pumps instead of genuine Honda pumps have not had great success.

Many stories here and on other sites about it failing to work and I don't recall ever seeing a story from someone that's had good luck trying that and making recommendations about what to buy or how to go about doing it.

Never tried it myself either.

had a similar problem on 2004 bf150. Pumped the bulb it got rock hard but no start. Opened the drain line on VST no gas. The float needle was stuck closed. changed. the needle valve problem solved.
 
Blackeyes02,

Thank you for posting your FIX. I tend to think that running the pump with no fuel might damage it pretty quickly. Was your pump ok after you discovered the stuck float valve?
Definitely something to keep in mind when working this problem.

I’ll for sure will reply once I get to the bottom of it. But I won’t know till I take it apart. Maybe next week tho. Ed
 
Hi again. I located a complete working used vst Assy. It bolted up perfectly and all the hose connections were the same except 1. She fires right up and purrs like a kitten. Question I have is does the different hose location make a difference? Parts catalauge says it is regulator relief hose. I’ll attach the pics. The first would be the one I took off and the second the one I put on. Ed

Sorry. Forgot to attach the one I put on. I’m computer challenged. The one I put on. The smaller nipple I am referring to comes out tight near the bigger one on top. I hooked the hose there. Not sure what the long term effects will be but seems fine right now. Ed
