Hi,
I have a couple of issues with Tohatsu (MD90B) which no one in Finland seems to know anything about.
Few weeks ago engine started coughing when trolling. When I quickly gave it more rpm it put out a huge amount of exhaust and I could continue trolling for like a 15-30 mins until same thing happened. I kept going two more trips, but problem got worse and it started coughing after 10mins of trolling. I was told that the engine uses too much oil. Possible uses the oil % that is used when driving 4000rpm or something like that or it has left the running in -mode on.
Also sometimes when trolling engine raised rpm itself.
I read the diagnostics and it gave me codes:
4500rpm - battery-light ON - Oil-light flashing.
And 4000rpm - battery light ON.
And 4000rpm - battery light ON - OIL light flashing.
I found this engines MD90B service manual and it gives nothing on the first one.
And some battery failures on those two other.
So, I bought new battery with 993cca and thicker wires. Thinking that my old battery wasn´t enough for the ECU and caused that "too much oil" -problem. I also erased the fault codes and did the ECU/TPS reset.
But now engine didn´t even start. It tried but didn´t start.
Found out that the cabels were istalled wrong, I adjusted the cabels so the advancer arm now touch the close-stopper and did the TPS/ECU reset again. Now engine starts but it dies everytime i put gear on.
So, I tried to fix a problem but caused another one. Help, what next?
Ps. Found a MD90C service manual and it shows Oil pump malfunction on that first fault code..
