I have a 03 2500 4x4. about a month ago i went to start my truck and it took about 20 sec to start. So i figured it was the fuel filter changed it and it started fine for about 2 days. I thought maybe the lifter pump was going bad so i changed that to a carter in line pump using a fitting on the back of the filter housing. The truck started fine for a day. I checked to see if the pump was pumping fuel by having some one crank the motor over while i looked in the filterhousing and its getting fuel. The only way i can get it started is by unscrewing the filterhousing cap and sloshing the fuel around until its foamy then it will start around the third try. When i shut it off it will restart about five times then i have to do this again. If i drive it it runs great idles good has power etc but wont start again unless i stir the fuel up. I have not notiiced any leeks in the fuel system. Any help would be great i dont want to have to borrow my budies ford!!!!!!

 

Check fuel pump pressure while running.

 

The source of your problem will be the injectors. Its an 03 thing. I went threw it last fall. Its a great time to get aftermarket ones if you dont have a warranty. The injectors leak off the pressure slightly and it make the lines get air in them and hard start happens.

 

Thanks guys! I talked to a diesel mechanic and he said the same thing about the injectors but that i should check all the injector lines first. Il let ya know what the prob is after i put a new starter in it!!!!! Or if it ever gets fixed

 

It was #5 injector that went bad

 

My brother had the same thing happen, changed a injector, 2 more went bad within a week. He replaced them all with II 3 flows, problem solved for a couple months, now he has a appointment Tuesday, same issue.

 

Thats not good!! Theres a guy that rebuilds them 2 hrs away from me for 175 bucks.im gona drop the injector off tuesday. I would replace them all but im short on cash. Well see what happens.
