I had the same issue on my mercury 115hp. Thanks for the video 👍

Glad it could be of help to you

Thanks for video, useful for df90(2001year) too.

[@jerrycox1512]

Outstanding video! Thanks a heap!

Just fixed my issue today, thanks for video

[@efarmer46]

Glad I could help.

Great video, I have a similar issue. However, a friend suggested running the engine under power with the cover off, as he had the same problem and found that his spark plug coil was bad, causing arching when the cover was on and the bogging down problem went away when it was off. My mechanic said that could be an issue, but also suggested cleaning the IAC valve might work too. Before I try your fix, did you ever look at those two issues. BTW, I did run my engine with the cover off and it ran fine! Now I just need to figure out why that is.

@@fjpace4 you may want to look at the molding plug if runs better with cover off that would be my first inspection , it’s a steel plug on the side of some engines and it corrodes around it and causes those symptoms. Steel and aluminum sometime cause a none dielectric union which causes issues

[@efarmer46]

Then next the iac valve

Nice video thanks for making it. I dont have the issue yet but its good to know if it happens to mine.

[@efarmer46]

You are very welcome thanks for the positive comment.

Bonjour, Sur la pompe il ya une durite (tuyau) jaunâtre en bas , est ce qu'il se raccorde quelque part ou il est comme ça svp? Sur la vidéo il disparaît a 32:31 donc je ne sais pas si il se raccorde quelque part ou pas ! 😁, en vous remerciant

[@efarmer46]

The yellowish tube you mentioned is the drain tube from bottom of vst tank it’s loose and a drain tube not connected to anything it’s just a drain tube for high pressure vst tank.

[@mrmrs8202]

@@efarmer46 d'accord, j'ai refais toute l'installation des câbles et j'ai vue ce tuyau tout seul qui m'a un peu fait peur 😁, merci beaucoup pour votre prompte retour, et bonne continuation 👍😉

Hello!I have a problem on a suzuki df 90 A 2009.. I have no spark and the trim does not work, and when it is connected directly to the wires, then the trim works.. is it the ECM? when starting I have a long beeeep pause of 5 seconds and then a beeeep for about 3 seconds and so on

[@efarmer46]

It sounds like you might have a ground issue check all grounds on motor and battery.

[@efarmer46]

On second thought check your water fuel separator for fuel blockage.

[@trumpet1783]

Thanks for the answer, but it still doesn't work.. there is current all over the engine.. there is a voltage of 12.70 v in the trim switch... but something is not allowing it to pass current.. the voltage regulator is new,,, the trim relay is new ..relays those little white cube ones are new...only I suspect the ECM is gone..anyway thanks for your time..Sasha

[@efarmer46]

I may misunderstood your question if I read it right check your kill switch a bad kill switch will cause no spark.

[@trumpet1783]

kill switch is new, rectifier regulator is new,

[@efarmer46]

I would trace all wires to ground even all the wire plug connections you stated you have power on one side but no ground so that’s what I would do it will be a time consuming task to trace electric gremlins I have had them this past week end and it was ground losing connection sorry I can’t give you a more straight forward answer but I go to all grounds every time I have an electrical issue. I don’t think it’s ecu but…… have you had and severe lighting lately sometimes I’ve seen a close lighting storm strike will fry an ecu. Just guessing at this point I would trace all connection from ground before you buy and expensive ecu. Good luck and any more question I will be gladly to try to help and thanks for reaching out.

I don’t know your exact situation, but you can have 12.70v even with a poor connection, but you wouldn’t be able to pass high current. I would check and double check and clean every connection from the battery to the battery switch and all the way on through. If you still can’t figure it out, replace the battery with a new one and retest. A bad battery can charge to the right voltage, but fall on its face under a load.

@@TheSaltyExplorerthis 👆 The ecu doesn’t regulate current. If you have a current problem, it’s either wiring or the batteries or a charging concern. There’s not enough info provided to make any further suggestions.
