CH680-3107 New, wont stay running, 2284 tractor
 

New 22.5 engine complete, Fires and runs for one second, Only when accelerator is moved from low to high, then dies. battery hooked up correct, plenty of fuel from pump, tank full, all wiring fit and connected. Oil full to the mark. Any ideas of where to check first?

You state the engine is brand new. I am assuming you have documents that came with the engine, to include Installation Instructions. With that in mind, did it supply you with and Electrical Diagram...??

:bigthink:

The Kohler Command had four Ignition Options:
(A) Standard Fixed
(B) Smart Spark
(C) Smart Spark Advanced
(D) Digital Spark Advance Ignition, DSAI

As best as I can see, your engine is (A)...????

no install papers, No diagrams. But it fit perfect. I checked the wiring from old engine and every wire is the same, best I could tell without pulling engine., I checked low pressure oil wire, it goes to same place in harness.

It seems as if I pump a shot of fuel by working the accelerator

It sounds like you have a Fuel Delivery issue.

SO....you just plugged this new engine connector into the 2284 wiring harness connector...??

:bigthink:

yes, all connectors were the same and same number of wires.I just looked again, red purple, green, blue, and white wires running to the connector from the engine side . On the old engine the purple wire is cut. it runs back to the solid state ign. on lower side of engine

Can you snap a few Pictures of the Engine Connector, both front and back. Also snap a picture of the 2284 Wiring Harness Connector showing the wire colors, and post it here..??

ok, am starting to see a difference. not sure which one i have now
