im having a problem with my 03 cummins with starting the engine refuses to start when cold unless given a tiny shot of either. it seems as though the fuel is being deadheaded when cold because once it cranks over on the either the fuel is then let in. but when the temp gauge reads over 140 it will start up withing 3-4 seconds. please help no mechanic has been able to fix this or figure out what is wrong, thanks

yea could be weak batteries but if not. your return flow on your injectors is to high. went through this on my father in laws 03. had to replace all six injectors. exact same symptoms. your lights diming is prob caused by your intake air heater being on.
