I've got a customer's 2004 Dodge Ram 3500 in my shop. He just had a new fuel pump put in yesterday. The vehicle quit yesterday. We couldn't force it start or bang on the fuel pump to make it have a one shot chance at starting. Nothing worked. Does anyone know anything that could be of help. Any & all advice is accepted. The mileage is around 150,000. It has a 5.9 Turbo Diesel in it. More specific, if anyone knows or knows where I can get any wiring info on the fuel pump, I would greatly appreciate it. Thanks in advance.

For right now all I need is a Wiring Diagram or schematic of the fuel pump.

 

alldata would be a good start for diagrams.

 

I am a diesel mechanic and I have messed with those engines a few times and I also own one but it is a 2002. The 2003 and up are a little diff. I would maybe think there is a fuse blown, a check valve possibly stuck or maybe a missed wire. I will jsut say from experience start with the basics. Sorry I cant be of more help. Good Luck.

 

Have you checked the lift pump?
