    EFI Frontier problem (Kohler EFI)

    OK, so I dont get to use my argo very often. It has 99 miles and about 35 hours on it. It will be 3 years old next month. The machine has killed the battery when it sits from day one, never a big deal but it does it. Yesterday I unload the machine (it lives in an enclosed trailer in a barn) and the battery was COMPLETELY dead, no juice AT ALL. I swapped a good battery into it from my generator and put the charger on it for a while. Last time I let is sit for a while it was hard to start due to fuel draining back into the tank. I was going to hit it with starting fluid this time so I wouldnt have to crank so long. I pulled the air filter cover off, and tried the starter--nothing. I assumed it was lack of gas so I bumped it with ether and tried again--NOTHING. checked spark-none. I pulled the fuel lines off the mechanical pump and had plenty of fuel flow, pulled the wires to the fan off so I could hear the HP fuel pump cycle and it runs continuously with the ignition on. I have NO check engine light-not even a bulb check. I tried pulling codes and no light at all. I dont know for sure that its ever came on, do they? Are they wired in? SO, long story short the kohler dealer (good friend) says all things point to a faulty ECU. Anyone else have any ECU issues with an efi kohler? Everyone says they are buletproof but who knows. I have one on a mower that has been GREAT, but its a completely different EFI system. when I get it fixed it will get an optima battery and a manual kill switch-$200 for an ECU is not something I plan to do again. It should be under warranty from kohler but I can see them not warrantying this problem because of the battery issue. FYI I have used my battery charger on the battery before to get it back hot enough to start the machine after trying and not having enough left in it to start it-apparently thats a no no..

    Just finished putting the Argo back together. The ECM WAS FAULTY. Not sure why, not sure if it will be warrantied or not but at least its back running. FYI, Still do NOT have a check engine light on the dash. No bulb check, no code read possible. Not sure why. I was assured by a dealer that the check engine light DOES function on these machines, unsure why mine is not. Bad digital display (bulb etc) or not wired in? Hope to get that figured out soon, but at least I can use the machine.

        MY argo dealer is in Adair Ia, I am in Birmingham AL. There is an argo dealer close, but they only sell the HDI unit (wont even order anything else) and I doubt they are a kohler repair center. Machine is OUT of argo warranty, but has one month left of the Kohler engine warranty. These things are so different to work on, not too many kohler dealers will touch them-its not like working on a lawn mower. I think I am on my own with this one, but I feel like its in good hands this way. I am an accomplished mechanic, with tons of tools and the willingness to repair things correctly. all too often "mechanics" dont really care about what they are working on and leave things a little half assed. Not all, but a lot.

              Well, I have replaced the ECU to get the machine running and now I am going to figure out why I have no check engine light. Thats a fairly necessary thing on an EFI engine.

                Should the check engine light appear on the display when turning the key to “on” ?
                I’ll have to check my display...

                  I spoke to a couple dealers that say yes. Both Adair and another in Nashville TN. I really dont recall ever seeing it on mine, but I never looked! I do know it should flash codes if you cycle the key correctly. Mine does not, not even an all clear code.

                        Plott, is your machine water cooled?

                            OOPS crossed threads, the check engine light should do the flashes if cycled 5-6 times quickly.

                              Book says 3 times, starting off, ending ON.. Maybe it takes more? Still on bulb check but I will try more cycles. Mine is air cooled, they would be completely different engines, but please let me know what you find it may still help.
