Need some help! Below +30F, the truck needs the block heater to start. This is a recent problem, as years past I have started the truck easily down to -10F. The engine will crank and crank and will not catch. I have experienced longer crank times lately and have had the TSB done to the ECM for long crank times. It still leaves me plugging it in to start. It has thrown a P0480 code, "clutch fan circuit", which has not cleared. Checked the lift pump it is steady at 7psi at start and idle.
Any ideas would be appreciated.
Thanks!
