96 7.3 not running

I have a 96 450. Truck ran fine. Parked and would not start. 140k on miles. Computer check shows everything passed. Changed cam sensor. no change. Will crank but no start. Glows plugs fine. Can hold a rag soaked with fuel in front of air intake. Truck fire right up until fumes burned off. low oil pressure at 25lbs.
Any thoughts?

x2 fuel pump. also load test your batteries. (pull cables for this) if you have one bad battery it can screw with your head.

things to check, injector harness, ipr and ipc connections, etc. without the rag in front of the filter do you get any smoke? i assume you check the fuel filter?

Thanks guys.Just put the pump on. Guess the turbo guys didnt talk to the fuel guys about the banjo bolt. Fuel filter is new. Truck the same. Batteries new but shop wore them down. recharging now. Guess next step is ipr or pull valve covers.

I've got a '96 F350 with a similar issue, only mine won't fill the fuel bowl. I've only got a little above 1/4 tank of fuel, thinking my pickup tube might have come off in the tank or something. I can hear some sucking sounds when cranking. Will put a few more gallons in it and see what happens. Will let you know what it turns out to be.

you can hear a sucking noise over cranking? do you have an electric conversion?

Nah, I was kneeling by the side of the vehicle while the wife cranking it, when she stopped I could here some gurgling in the tank. By the way, sorry to hear about your truck being totalled, hope you get it replaced with another PSD soon! I've only had mine a couple weeks and love it. Would love it even more if it would start - Blaine

Not sure, but haven't seen any leaks. It just seems wierd that it would be running fine, then after sitting for a week not want to start. Will be adding more fuel in the tank tonight to see if that helps. By the way, here's one in NM where I am that looks like a decent deal, not sure where you're at but if you're close might be worth the drive - http://albuquerque.craigslist.org/cto/2385113277.html
