I connected a scanner and pulled two codes.
1) p0401
2) p0277

I cleaned the EGR valve about a month ago but the truck has 230,00 miles on it.

This forum helped me isolate the no start problem last month .... It was low voltage on the FICM. I had it repaired and it was running great. I checked the batteries:battery voltage and it is 12.5 volts.

The truck isn't running right at all, seems like a misfire.

Hoping for your help again.

 

p0277 #6 injector circuit high. FICM detected a short to ground or a defective coil
p0401 Egr insufficient flow EGR valve position does not match desired limits based on engine speed and load.

EGR sticking egr sensor biased [bad] Ep sensor biased

re-clean egr valve check wires to #6 injector or change injector if no wire problem found

 

Thank you for your reply
