vp44 failure?

I'll try and keep it as brief as possible. The last month or so I've been losing power. My RAM is a 98 24v with 160K on it. It seemed like a possble lift pump problem and I was planning on replacing it when I replaced the fuel filter. Last Fri. eve. (before the pump and filter replacement) my truck would die at a stoplite and I could restart it and I managed to limp it home. I replaced the pump and filter, purged all the lines up to the vp44. I tried starting it and got nothing, it would crank good but no fire. I cracked 3,4,5 injectors and cranked it several times for 15 to 20 sec. and no fuel at the injectors. I tried locating the bleed valve on the pump and couldn't find it.

What about checking the pump relay, ECM (Idon't have a scanner), etc.

My local dealer is a joke and is always trying to get in your pockets. My Cummins shop is about 85 miles away.

Any suggestions?

Thanks,
Vern
