05 ford f250 diesel cranks no start

Question

engine will not start has codes p2285 p0672 p0673 p0676 c1233 c1234 fuel pump is working and oil pressure is good. Any ideas that may fix this problem are greatly appreciated

Answer 1

P2285 ICP circuit low

P0672 Glow plug circuit cylinder 2

P0673 Glow plug circuit cylinder 3

P0676 Glow plug circuit cylinder 6

C1233 Input wheel speed sensor LF signal missing

C1234 Input wheel speed sensor RF signal missing

Even with the code P2285 the engine would still start, the ICP code are commonly seen when the engine does not start, If you can use starting fluid after the MAF (mass air flow) clear the code when the engine is at warm temperature do a KOEO (key on engine off) test and with a KOER (key on engine running

​ On this Ford the engine did not start, removing the fuel test shrader valve and bleed out the air trap in the fuel line ( due to owner removing the fuel filter) by cycling the key repeatedly. The code that where set was glow plug code and a ICP code, once started and codes cleared, retest for code showed no codes,

Comments

thank you for your help. Also, would a bad battery cause the no start and these codes. Because I checked them and one of my batteries is week

Yes it would, that I forgot to mention, when its a diesel if there is no sufficient cranking RPM it will not start.
