Long time lurker here......
So this winter has been rough. Basically I have 3 codes on my edge evolution telling me I have 3 bad glow plugs. I have to plug the truck in damn near every day to get it to start in the morning. When looking at the ECT and EOT
, if it is anything less than 35 degrees, I cant get the truck to start for the life of me. If I plug it in, the block heater works great (thank god) and the temp climbs. Once around 40 degrees, the truck fires up no problem. I am running Rotella T6 in the winter with guidance from here. The FICM
was repaired by FICMrepair.com about 1.5 yrs ago. When its really cold, I glow the plugs for 20 seconds, then glow them again for 15 and try to start it. Usually its a no go.
My questions is would 3 bad plugs really cause a no start or could it be the GPCM. Is there a way to test the module? I have read the tips on the glow plug testing but in all honesty I think I'm just gonna replace all 8 if I am in there. I just think something more has to be wrong for this thing to not want to start at all when the motor is 32 degrees. When it warms up to at least 40 it starts flawlessly.
My programmer has the following 3 DTC
No check engine light on. If I try to clear the codes they come right back.
Anyone got any ideas at all?
Any help would be appreciated.
