Cummins engine barely starts
Years ago we had an issue with a fuel cut off solonoid for our Cummins engine model 6C 8.3. It would it be difficult to start and I replaced the solonoid and it would start right away. now when we g...

Still not knowing if you mean low cranking rpms or takes longer to fire but appears to crank fast enough, I'll go with low cranking rpms.
The solenoid is basically an externally mounted relay and generally they work or they don't. A "delay" wouldn't cause low cranking rpms (from low voltage or other causes (like worn out starter motor or low cranking capacity of batteries or bad cables/connections).
It an on/off switch that triggers the power to the starter motor. could be a bad connection or burnt contacts in the solenoid though. Although the contacts in the bendix would be the ones carrying the high current from the batteries to the starter motor.
Unless hard to access in your chassis, the solenoid is a cheap part and easily replaced without removing the starter. If you can physically reach it and have even a basic set of hand tools and understand righty tighty lefty loosey, it's a 1/2 a beer job.
