Cummins ISC hard to start, dies after 2 seconds
Like the title says, I'm working on an ISC with issues. Its in a Case fertilizer spreader machine. The machine has done this several times before but this is the first time I've been the one called to work on it. I replaced the ICV modulator and the transient suppressor as per Cummins troubleshooting steps and what the dealer told me to do, and it fixed it for about 2 hours, then it went right back to hard starting then dying. I installed new batteries and cleaned all connections, Fuel pressure is right where it should be while cranking and picks up immediately once the machine fires. Lift pump is running and pressure is good.
Anybody have any ideas? Cummins says put an injection pump on it ($4k), customer says try everything else first. lol
