I did not charge him for the parts that I tried and failed to fix the problem with. I still have them. The dealer did charge him of course. His bill was 782.00 from the dealer.

The owner got back to me with what was done to fix it at the dealer. They basically started changing parts until they got the correct one. They changed the MAP sensor, Intake air sensor, and the injector. All tested good when I checked them. I'm assuming the injector was the culprit, but you...

Thanks for the reply Lugbolt. I checked the pressure and flow, all looked good. I put a new filter on also. I sent the machine back to the owner.

I checked one last thing before throwing in the towel. I thought maybe the valve timing was off. I checked it and is was correct. It's a goofy way to check the timing on this thing. The crank pulley has an arrow that you line up with a mark on the case and a paint dot on the pulley that you line...

I got the new/used coolant sensor and once again it made no difference. I'm done. I let the owner know that I had failed. He said he'll have to take it to the dealer. He said he would let me know what they do to fix it. I will post what they do as long as he lets me know. To be continued......

Yes, I checked both according to the manual. The thing that I didn't do was take the coolant sensor out and heat it up in water to watch it change. It was at the approximate ohms for the room temp. I sure hope this is it. I'm ready to call it on this thing. It has become that thing to where its...

Ok, I'm back at it after letting it sit for a bit while I got caught up on the other machines in the shop. I thought that since one of the things the ECM relies on, is air pressure readings from sensors, I'd fix the exhaust leak. Well, it turned out that the manifold was broken and had a major...

papajoe Did you test pressure first or just change it? Mine tests good and has good flow. I put a new filter on it but it also made no change.

I'm not sure of anything at this point. The spray pattern looked good when I pulled it and sprayed on a piece of cardboard.

I received the ECM and there is no change. I was afraid that was going to be the case. Back to scratching my head.

Intake air sensor tested good also. I hate to buy the ECM because so many times its not it. I don't know where else to go though. I will post one way or the other. So many posts end without a conclusion and it drives me crazy!

Thanks Clutch, No lights come on, only when I unplug a sensor. I have the manual but missed the section on fuel injection control. I tried unhooking each sensor while it was running and every one made a change in the way it ran. I think I'm down to replacing the ECM. I found a good used one...

That's all for today. Thanks Clutch for giving me some things to try. I try to stay open minded but tunnel vision takes control way too often.
