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
you also want to check your injectors. the number 1 injecter is what fires the truck off to start it. i had an issue like this about a yr ago and ended up replacing all six injectors. because the only way my truck would start was with either.
