My 04.5 2500 is very hard starting. It starts when it is plugged in but still cranks over longer than it should. I have checked the relays to the grid heater, and also the amperage from the relays to the grid heater. Most people I talk to about it say that it is probably the injectors but when it's not plugged in and doesn't start there is absolutly no smoke at all coming out of the tail pipe. This makes me think that it is not getting the fuel it needs to start. When it is running it runs good with no hickups or loss of power. If anyone has any ideas I'm open for sugestions before I go and spend 2 grand on injectors.

It does sound like an injector issue, the return too much fuel to let the rail pressure properly build. I would pull them and have them tested. DDP, II, and several others can do this for you. Its about 30-35 ea, which goes towards the repair bill if anything is wrong.

Try changing the fuel filter first, @ $14 it's a lot cheaper then $200 to have the injectors cleaned and tested.:smart:Might want to run a few tank fulls of Lucas injector cleaner through the truck first also. I like try the cheaper things first, cause I be poor

Thats a good point, you never know. I sometime forget not everyone filters their fuel quite like I do, or uses additives every tank.

Thanks for the input fellas. But i run Stanadyne every tank and change my fuel filter every 6000 miles.

Just ordered injectors today. I hope I'm not wasting my money. The other day the truck hick-uped going down the highway. So I parked it till I can change injectors this weekend. any addvice?

Hi Windy, get your injectors yet? A local shop has this webpage with an installation guide. Thought it might help. https://www.dynomitediesel.com/Products/TechnicalGuides/Default.aspx

Relaced them two weeks ago with ddp 50 horse injectors. It was a little easier than I thought it would be. I actually got by without any special tools.
