Hi everyone
I've got a problem with the N14-435 Celect in my IH 9400 truck. Long story short, it ran out of fuel. I changed the main filter on the pump head as well as the water separator filter on the firewall as I've done before when I ran the thing out of fuel. Filled filters, etc. The engine will start and run on full filters, but usually requires a shot of ether to start. It will generally run for 5-10 minutes and quit. I can shut it down and sometimes it will restart on it's own. Sometimes requires ether. When it quits it will often produce white smoke. Sometimes no smoke which leads me to believe it's not getting fuel. Refilling the filters will generally get it running again.
Thus far I've blown the lines back to the tank and they seem clear. I can pressurize the tank and force fuel through the filters and out the bleeders on the pump. I've replaced the pump. Filters multiple times. I've cleaned the check valve in the ECM cooler plate (and found nothing). I've made jumper lines to eliminate ALL chassis fuel lines and run direct from the tank siphon to the engine filter head. Nothing has made any substantial difference.
It's behaving like a bad crank sensor... will sputter and quit a few times and then start.... but it's not putting the engine light on.
I don't see any obvious defects in the engine harness. I spent a couple minutes twisting and forcing it when the engine was running, all to no effect. The engine ground does look ugly... but nothing else is giving issues and many things ground on that surface...
I'm going to see if I can get some codes from it.... but otherwise, at this point, I'm open to any and all suggestions. Thanks
