A friend has a Kohler SV600S motor that starts and dies after about 5 seconds. He has cleaned out fuel tank, changed gas lines, fuel pump, coil, spark plug wire, spark plug and carburetor with no good results. Anyone have any ideas I’d really appreciate it.
Kohler SV600S starts and runs for 5 seconds and dies
I’m not sure. I’ll have to check.
As in like a new one, clean?
From the tank outlet to the carb inlet, all the way?
Was this tested? Does it work and actually pump fuel?
These items tested? Can this ignition system jump a 1/4" gap in free air?
I'm with kbowley, carb after fire solenoid working?
Will it fire with starting fluid sprayed into the carb throat, choke and throttle wide open?
You need 4 items to make it run. Air, fuel, spark (at the right time) and compression. Deduce what you are lacking.
I have searched everywhere but cannot find a low oil pressure switch. I have found that the new fuel pump isn’t pumping. It’s vacuum operated fuel pump so gonna check vacuum where it comes out of the motor.

Are you sure you have the lines hooked up to the pump correctly?

Check for battery voltage to the solenoid on the carb with the key turned to the on/run position. Not all of the Courage single cylinder engines had oil pressure switches so that could be why you're not finding one. It sounds to me like you might be getting voltage to the fuel solenoid with the key in the start/crank position but not in the on/run position.
You could try unplugging the fuel solenoid and run a fused jump wire from the short wire coming off the solenoid to positive terminal of the battery. If the solenoid isn't getting power from its designed source this will bypass that and should run.
