Have Truck Repair Questions? Ask an Expert
Thanks for asking your question. I will try and help you out.
Does the yellow check engine light come on when the key is turned to the on position?
Can you get me the engine serial number please?
May I ask why the engine was overhauled? Was there a failure?
Thanks for the information.
So was the crankshaft replaced I assume? Was a short block installed?
The reason I ask is because there are two crankshafts for the C12. The early models had a chopper wheel bolted on the front of the crankshaft. The later models just had a tooth knocked off the gear. That's what you should have. If they gave you the early crank with a chopper wheel the engine will not start. It takes different software. Do you know what crank was in the short block?
I see. Thanks for the information.
Unfortunately a 9NS will not work with 2KS electronics. The 2KS needs to have the crank sensor on the crank gear. The sensor you see in the flywheel is a rpm sensor. Not a tdc crank sensor. I am sorry. I wish I had better news.
The cam sensor is also different than a 2ks.
The best way to repair would be to install 9NS electronics. To keep the 2ks electronics. The cam and crank will need to be replaced. I am sorry.
Please reply back if you need more help or have more questions. I am happy to assist.
You would need all of them. The ECM, all the sensors, and the engine harness.
The electronics of a 9NS and a 2KS are completely different.
Yes the ECM connector will need to be changes.
The injectors should be fine
