Fixed FICM Still Cold start Issue! Help, Thanks
Need help, searched threads cant seem to find the answer.
Fixed FICM 2 weeks ago, works now, Been But having issues starting, don't believe FICM related there is absolutely NO stiction now when it starts. Colder weather to -8 it starts fine but colder lately -12 or colder it wont start up! I try to start the truck and it almost starts then re cycle the glow plugs and same, almost but wont stay running. The only success I have in the cold is over cranking the starter. I know it is hard on the starter but it's the only thing that works, keep the starter turning as the truck seems to start and it will. Now I notice the lights on the dash flicker when I turn the starter over, It never did that before. also a slower cranking speed on the second starting attempt. Starts fine when the engine is warm or warmer weather.
New battery's 2 weeks ago, oil change 2 weeks ago 5w-40 synthetic, fuel filters 2 weeks ago
Could it be alternator? fuel pump? or something else? Thanks for any help!
