I have a ditch witch SK650 with the Kubota D1105-T engine. The customer states it starts and dies after a few seconds. I have found there is no oil pressure. The oil pressure switch is a 7 psi normally closed switch. I had changed the oil and no change. New oil pressure switch just to make sure. If you leave the wire off the switch, it stays running. Are there any common issues found for losing oil pressure?
