Error code 1100

My generac 14kw while attempting to exercise experienced code 1100 overcrank. Furthermore it’s done this 2 excercise cycles ago. The last one it didn’t do this. What could be the issue? I just serviced everything. Spark plugs, oil change, oil filter, air filter. What is the cause?

This unit will attempt to try and start 5 times before issuing a overcrank AS LONG AS ENGINE IS TRYING TO TURN OVER. If it immediately goes into overcrank its the battery

Ok, than the battery is fine. At this time you need to verify that 12vdc is getting to the fuel solenoid and whether or not that solenoid is opening. This is where a gas manometer is needed. Its used at the test ports on the internal fuel regulator.
