I have a 1999 Suzuki DF70 4 stroke....Have had a HORRIBLE time getting it fixed. Took it in originally for flashing lights and alarms and occasionally starting hard. Took it to a shop and they went through it (injectors, spark plugs, fuel rail, etc., etc.) cost me $800 and could not figure out why engine was still sending faults and alarms. Took it to a semi local suzuki dealership. They replaced the (spark plugs, fuel lines,etc. etc.) came to the same conclusion as previous shop BUT they say the ECM/ECU is BAD and it is not communicating with the rest of the engine. The engine when new in 1999 had the ECM/ECU replaced. How often and likely is it that this engine needs a THIRD ECM???? At what point is this a manufacturers defect? Mind you a new ECM is $1600 and the dealership cannot tell me if I replace it the engine is fixed and ready to go. Also, the dealership when i orginally brought it to them (3 seasons ago) the service manager at the time told me after they "said they fixed it" told me they were gonna cut the wires shutting off the "alarms" and dont worry about it the engines fine. If anyone could give me some advice.
