Thank you! I've had a busy weekend at work and will be working on the tuck this week, I really appreciate all of your help! Trying to find the pigtail for the pickup pump, I've got one at the shop.

I had made a mistake with the FORCE system I actually have the FASS pump system. Is there a fuse link in the wiring to the ECM? Where would the communication issue originate from, and how do you troubleshoot it?

The pick up pump brand name is "Force". Which is located on the side of the block, where the "Carter" pump was. The Carter pump came stock on the engine block. Which is the fuel pump. I have a pump in the tank that gives low pressure, then the pick up pump on the side of the block gives the high pressure. When I started having the problem I only got a reading of low pressure. When you bump the key the block pump should boost to 20 lbs, but now I have no power to the tank pump and no power to the pick up pump. For the codes I've gotten 1694. The injector pump has less than 1000 Miles on it. After changing both fuel pumps (tank and pick up) I had 22 lbs of pressure. Then I lost everything after about 5 Minutes of running. Since then It's been a few weeks and I've been tracing and testing wires, to try to find the source of the problem. The engine hasn't ran or started since then.

Thank you very much dripley, I have another question. So it originally started with not having enough fuel pressure. I was only getting 4 lbs of pressure out of the tank, and the pick up pump wasn't putting out any more pressure. So I've changed the pickup pump to a force pump. Then the truck had ran for a little bit, but the throttle positioning pedal went into safe mode. So now the truck will not run at all. So then I changed out the tank pump and it still will not start. So now I'm not getting power to any of the plugs.

Hi, I'm new to this forum and I'm in search of a Wiring Diagram for a 2001 Dodge Cummings Ram. My current issue is that there is no power to both fuel pumps and the relay keeps clicking on and off. I can't find the power source, and I haven't found a bad fuse. Thank you, Tommy
