03 3500 6 speed no start issue
 

Alright I have searched and searched for a week and can't resolve this issue. Driving on highway and truck shuts off. Checked codes and replaced crank position sensor and fca, the only code left is p0480 fan clutch low speed circuit open. Can this code shut down the truck? I can't find a relay for it anywhere , but the truck never gets hot and was running great before this happened now it won't start. Someone please help , any info is appreciated

No I don't think it can cause the motor to shut down.
Are you getting any check engine lights?

I also got this for the p0480 code. (P0480 Cooling Fan 1 Control Circuit Malfunction)

I read it could shut down the ECM I'm baffled on this issue and yes I have check engine light but have resolved all codes except this one

Can you tell if your electric fuel pump is running?

Yes it's pumping I have a raptor 150 pump
