03 Duramax no start ?'s
Hi, im new here to diesel bombers and am fairly new to the diesel world. I have an 03 Duramax with 78k and for the last month or so I've had problems starting it when it was hot and cold. So I replaced fuel filter and filter housing and didn't have any luck. If I prime the system it would normally start good for about a week and then get harder and harder to start until eventually it won't start at all.. But now priming it does not help, it will crank and crank but won't fire. At first I thought it was the injectors, but I'm not getting any white smoke and there is no diesel in the oil. So today I got curious and sprayed starting fluid in the intake and it fired right up. ( I know starting fluid is bad for diesels I just tried it once) And I took it for a spin and it seemed to run fine, but as soon as I shut it off it wouldn't start back up. So now I'm thinking injection pump? Could this be a possibility? The dealership can't get me in till next week to check balance rates and get the diagnostics ran. Any help would be greatly appreciated, Thank you in advance.
