Wow! I'm no mechanic by any stretch of the imagination, but I do see a common cause with all these coded issues, and that is open ground!!! I've checked the relays by replacing them with the horn relay that I could verify works. When the problem started, there was a great amount of corrosion on the batt terminals. Also, one batt was completely dead and wouldn't take a charge. I've replaced the dead batt, cleaned the terminals, and put a slow charge on the batts.

Just got the codes pulled up, again: PCU P1388, P1693; ECU P1693, P0380, P0215, P0237, P1689. Thanks!!

Thanks for the replys to my posts! When I get home from work I'll start working on it again! I know the lift pump is working as it should, I crack lines and fuel sprays everywhere! The VP was replaced several years ago by a dealer when the truck had 98,000 miles on it. It now has 136000. It has shown two sets of engine codes, one being the P 1698 you mentioned above.there were several others that I can't recall not having them in front of me. Just a thought, could I have a bad ground somewhere? I had a lot of corrosion on my cables when I started this!!

OK, guys, I cracked the fuel lines at the head, no fuel!! I have good pressure to the pump, but nothing out!! What turns the fuel on and off in the pump???

Don't have a FP gauge.I'll try loosening the lines. Thanks!!

No, I didn't, I made sure the filter was full and there was pressure going to the injection pump.

Thanks for the tip!! Tried this, no luck!!

I have a 2002 Dodge 2500 w/ approx 135000 mi. the injection pump was replaced by a dealer when the truck had 98000 mi. The truck sat idle for about three weeks and when I went to start it the batts were very weak, turned over twice and went dead. I charged the batts, cleaned the terminals, but the engine would just spin. The lift pump is working, and there is fuel in the tank. I also changed the fuel filter and drained the water separator. Still, no start! Help!!!
